Highland Baths At Kerlingarfjöll: What To Know Before You Drive

The Highland Baths sit at Highland Base in the Ásgarður valley at Kerlingarfjöll, three linked pools and a cold plunge on the bank of a highland river, and they are only open from 15 June to 30 September. Everything else about visiting them flows from that fact.

Short answer

The Highland Baths at Kerlingarfjöll are open 15 June to 30 September only, with general admission from 11:00 to 23:00 and last booking at 21:00. Adults pay ISK 5,500 and children aged 0 to 11 pay ISK 900, and admission is included for overnight guests at Highland Base. The drive up the Kjölur route is a mountain road that opens depending on snowpack.

The Highland Baths at Kerlingarfjöll are the most remote ticketed soak on this site's map, and they behave differently from every lagoon on the Ring Road. They run on a hard seasonal window, they sit at the end of a mountain road rather than a paved highway, and their public rating currently rests on a very small base of reviews, which matters if you are the kind of traveller who checks scores before booking. This guide sets out what is verified: the season, the access, the prices, the rating basis, and the roadside alternatives that stay open when the Highlands are shut.

What Are The Highland Baths At Kerlingarfjöll?

The Highland Baths are a geothermal bathing facility at Highland Base in the Ásgarður valley at Kerlingarfjöll, in the central Highlands between the Golden Circle and the north. The venue publishes three linked pools, a cold plunge, a steam room and a swim-up bar, all fed by mineral-rich geothermal water drawn from local fields, and it sells day admission to non-residents alongside its overnight guest packages.

Kerlingarfjöll is a rhyolite mountain range, and the colour of those hills, orange and ochre rather than the black basalt most of Iceland shows off, is a large part of why people make the trip. The baths themselves sit at the Highland Base operation in Ásgarður, which functions as the service point for the whole area. The water is geothermal and mineral-rich, and the facility layout is deliberately rustic compared with the purpose-built spas near Reykjavík: pools, a cold plunge, a steam room, a swim-up bar, and changing facilities, without the restaurant and retail layer of the capital-area lagoons.

The experience is closer to a backcountry hot spring with a ticket office than to a spa. That is the appeal and also the constraint. You are bathing at altitude, in a valley that is snowed in for most of the year, in water that the operator draws from the local geothermal field. The trade for that setting is a season measured in weeks and a drive that requires more planning than anything on the South Coast circuit.

For context on how the other end of the spectrum works, the big commercial lagoons near the capital are described in the guide to lagoons near Reykjavík, and the full price landscape across the country is laid out in Iceland lagoon ticket prices compared.

How Do You Reach The Highland Baths From The Golden Circle?

The standard route is north from the Golden Circle area onto the Kjölur highland route, F35, which runs between Gullfoss and Blönduós through the interior. Kerlingarfjöll sits off this route in the Ásgarður valley, and Highland Base is the endpoint. The Kjölur route is a mountain road, classed as an F-road, so it only opens once the Road Administration clears it each summer, and opening depends entirely on weather and snowpack.

The Kjölur route is one of the two classic highland crossings, and it is the one that connects most naturally to a Golden Circle itinerary: you drive to Gullfoss, the end of the paved Golden Circle road, and continue north into the interior. The Road Administration, Vegagerðin, publishes a seasonal map showing where mountain roads are open, updated as conditions change, along with an information page showing the estimated opening dates of the main mountain roads. That page is the only authoritative source for when F35 becomes passable in a given year, and it is where you should check before committing to the drive. The administration states plainly that the opening of mountain roads depends on weather conditions in spring or early summer, with snowpack having the greatest influence on opening times, and that wet roads can also cause roads to open late.

Because the drive is the hardest part of the visit, it deserves its own planning pass. A rental agreement matters here: many Icelandic hire companies prohibit F-road driving entirely, and others require a specific vehicle class. The Road Administration's own guidance on mountain roads and their seasonal opening is the reference to have open on your phone. For live conditions and alerts during the trip, the safetravel.is service run by the Icelandic Association for Search and Rescue publishes constantly updated travel conditions, and the emergency number in Iceland is 112.

If all of this sounds like more car than you bargained for, that is a reasonable reaction, and the rest of this guide gives you the comparison points: what the drive actually requires, and which open-all-year soaks sit on the paved side of the line.

When Are The Highland Baths Actually Open?

The Highland Baths are open to the public from 15 June to 30 September only. Within that window, general admission runs 11:00 to 23:00 with the last booking at 21:00. For roughly eight months of the year, the honest answer to whether you can visit is simply no: the facility closes and the mountain road that reaches it is shut by snow.

That season is not a soft guideline. It is the operator's published operating window, and it aligns with the practical reality of highland access, since the F-road network that includes Kjölur opens in early summer and closes again in autumn. A visit in, say, October or May is not a matter of driving up and hoping; the baths are closed and the road is very likely impassable. If your trip falls outside the window, skip ahead to the alternatives section, because there are now good ones.

The comparison table below sets the highland option against the three roadside South Iceland tickets this site tracks, on price, access and season. It is the fastest way to see the trade you are making.

Venue Adult ticket Access Season
Highland Baths, Kerlingarfjöll ISK 5,500 on site F-road (Kjölur route), mountain-road vehicle needed 15 June to 30 September only
Secret Lagoon, Flúðir from $35 via the live listing Paved road off the Golden Circle Year round, daily
Laugarás Lagoon from $73 via the live listing Paved road on the Golden Circle route Year round, daily 10:00-21:00
Reykjaböð, Hveragerði from $64 via the live listing Paved road, 35 minutes from Reykjavík Year round, opened 5 September 2026

Note what the table shows. The Highland Baths are the cheapest soak of the four at the gate, and they are the only one you cannot reach for most of the year. Price is not the constraint here; the calendar and the road are.

What Does An F-Road Drive Require That A Paved Drive Does Not?

An F-road drive requires a vehicle your rental agreement permits on mountain roads, usually a four-wheel-drive with adequate clearance, plus fuel planning for long stretches without services, and a check of the Road Administration's live map on the day. A paved Golden Circle drive requires none of those things: any car, any agreement, and services at regular intervals along the way.

The distinction is legal as well as practical. The F prefix marks an official mountain road, and driving one in a vehicle your contract does not cover can void your insurance, a risk that matters more on loose gravel and river-adjacent sections than on asphalt. The Kjölur route is regarded as one of the more forgiving F-road crossings, but "more forgiving" is a relative term inside the Highlands, and conditions change with weather. The Road Administration publishes road conditions and weather through its traffic service at 1777 and its online map, and the administration's own seasonal pages are the source of truth on openings, as covered in the access section above.

Requirement Paved Golden Circle drive F-road drive to Kerlingarfjöll
Vehicle type Any rental class Four-wheel-drive with clearance, per rental terms
Rental agreement Standard Must explicitly permit F-roads
Road status check Not needed Essential on the day, via the Road Administration map
Fuel planning Services along the route Carry margin; long stretches without stations
Weather dependency Low High; conditions change fast in the interior
Driving time Short hops between stops A long interior leg each way

Build buffer into any Kjölur day. The crossing itself plus the detour into Ásgarður is a serious commitment of hours, and the point of the baths is to arrive with time to soak rather than to race the daylight. In late September, the tail of the season, the days are already short and the weather window narrows further.

What Does Admission Cost, And What Is Included?

On-site admission at the Highland Baths is ISK 5,500 for adults and ISK 900 for children aged 0 to 11, and admission is included for overnight guests at Highland Base. The baths also appear on a bookable listing at from $44 for a two-hour admission, rated 3.5 from four reviews, a rating base this page states plainly wherever it appears.

The on-site figures come from the operator's own published price page, and the bookable listing price comes from the live listing rather than the gate. The two are not the same product channel, and the listing price moves with the operator's own pricing, so treat both as planning figures and confirm on the day you book. What admission buys is the facility described earlier: the pools, the cold plunge, the steam room, and the swim-up bar, with food and drink sold separately at the bar. Everything else covered here is indexed on Lagoons in Iceland.

For a price comparison across the whole country, including the capital-area lagoons and the north, the ticket price comparison guide carries the full table. The short version for the South Iceland set: Secret Lagoon is the cheapest bookable ticket on this site's roster at from $35, Laugarás Lagoon runs from $73 with a two-course meal tier, and Reykjaböð runs from $64 with a 2 to 3 hour entry window. The Highland Baths' ISK 5,500 gate price is competitive with all of them, which is worth knowing, because the cost of the soak is rarely what stops people. The drive is.

If the price point appeals and the season or the road does not, the Secret Lagoon at Flúðir is the natural fallback: the same geothermal-water tradition, a paved road, and a year-round calendar. See the Secret Lagoon guide for the full picture, or go straight to the Secret Lagoon ticket page and Check availability for your dates.

How Does The Rating Compare Across The South Iceland Soaks?

The Highland Baths listing carries a rating of 3.5 from four reviews, the smallest review base of any soak this site tracks, so the score carries very little statistical weight. By contrast, Secret Lagoon holds 4.7 from 2,124 reviews, Laugarás Lagoon 4.8 from 74, and Reykjaböð has no reviews yet at all, having opened on 5 September 2026. Treat the highland score as a data point, not a verdict.

A four-review average can swing a full point on a single new review, and that is exactly why this page repeats the basis every time the rating appears. The highland score is not evidence that the baths disappoint; it is evidence that almost nobody has reviewed the bookable listing yet, which is what you would expect from a facility that opens for fifteen weeks a year at the end of a mountain road. The roadside venues, open all year on paved highways, accumulate reviews at a completely different rate.

Venue Rating Review count Basis note
Highland Baths, Kerlingarfjöll 3.5 4 reviews Very small base; a single review moves the average
Secret Lagoon, Flúðir 4.7 2,124 reviews Large, stable base
Laugarás Lagoon 4.8 74 reviews New venue, opened 2025, growing base
Reykjaböð, Hveragerði no reviews yet zero Opened 5 September 2026
Bar chart comparing review counts and ratings across four South Iceland lagoon tickets
The Highland Baths' 3.5 rating rests on four reviews, while Secret Lagoon's 4.7 rests on 2,124, so the two scores are not directly comparable.

What Can You Soak In When The Highlands Are Closed?

When the Highland Baths are shut, roughly October through mid-June, the open alternatives are the roadside South Iceland venues: Secret Lagoon at Flúðir, Laugarás Lagoon on the Golden Circle route, Laugarvatn Fontana on the lake shore, and the newly opened Reykjaböð in Hveragerði. All are reached on paved roads and all run year round, so an off-season trip loses the highland soak without losing the geothermal bathing.

The strongest of these for a Golden Circle itinerary is Laugarás Lagoon, which opened in 2025 beside the Hvítá river and sells three dynamic ticket tiers, with the two-course meal tier bookable from $73. It is the nearest thing on this site's roster to a destination soak on the paved side of the line: a new facility, a strong early rating of 4.8 from 74 reviews, and a location that slots directly into the standard Golden Circle driving day. The Laugarás Lagoon guide covers the tiers and the restaurant in detail, and the ticket page shows live dates.

Reykjaböð deserves its own mention because it is the newest option in the country. It opened on 5 September 2026 at the mouth of Reykjadalur in Hveragerði, 35 minutes from Reykjavík, and its base ticket includes entry, the outdoor ritual area with an event sauna, a cold plunge and a Kneipp pool, a wristband for lockers and payments, changing facilities and a towel. It has no reviews yet, which this site states plainly rather than hiding, and it is covered in full in the Reykjaböð guide.

Are There Other Remote Soaks That Compare?

Yes, though the honest comparison set is small. Húsafell Canyon Baths in west Iceland is the closest analogue: a guided soak reached with a short highlands hike, bookable from $76, rated 4.8 from 68 reviews, and open year round. Unlike Kerlingarfjöll, it needs no F-road, and unlike a roadside lagoon, the booked slot is the only access, since no walk-up gate exists.

The Canyon Baths experience is built around a 1 hour 45 minute guided tour from Hotel Húsafell that includes transport, a hike past Langifoss waterfall, and access to two geothermal pools plus a cold spring, with a maximum of 16 participants per outing. The pools are built with flagstone from the canyon floor and the bathhouse from salvaged timbers, and the whole thing is deliberately small-scale. It delivers the "soak somewhere genuinely remote" feeling that draws people to Kerlingarfjöll, without the mountain-road requirement, which is why it earns a place in the comparison even though it sits in a different part of the country.

The trade between the two is clean. Kerlingarfjöll gives you the rhyolite mountains, the interior crossing and the fifteen-week season; Húsafell gives you a canyon, a waterfall on the walk in, and a calendar that runs all year. If your heart is set on the Highlands themselves, no substitute will do, and the earlier sections of this guide tell you how to time it. If what you actually want is a soak that feels earned, the Canyon Baths deliver it with far less logistical risk.

Is The Highland Baths Trip Worth It?

For most travellers, the trip is worth it only if the season, the vehicle and the schedule all align: a visit between 15 June and 30 September, a rental that permits F-roads, and a spare half day for the interior drive. When those line up, the baths offer a high-altitude geothermal soak in a mountain landscape none of the roadside venues can match. When they do not, the paved alternatives deliver a better day for less effort.

The decision really does reduce to that alignment. Travellers who arrive in winter, or in a small two-wheel-drive, or on a tight Ring Road schedule, are not failing to reach the Highlands through poor planning; the facility is simply closed or impractical, and the honest move is the alternative. Travellers with a summer window and a suitable vehicle get something genuinely scarce: a hot soak at the foot of a rhyolite range, in a valley most visitors to Iceland never see. The rating basis, four reviews, tells you almost nothing either way, so decide on the landscape and the drive, not the score.

One last practical note, and it applies to every plan in this guide: conditions in the Icelandic interior change, and the sources that track them are live. Check the Road Administration's map for the road, safetravel.is for conditions and alerts, and the operator's own page for the baths on the day you go. A trip planned around those three checks is a trip that rarely goes wrong, whether it ends in the Highlands or beside the Hvítá river at Laugarás.

Common Questions About The Highland Baths At Kerlingarfjöll

When are the Highland Baths at Kerlingarfjöll open?

The Highland Baths are open to the public from 15 June to 30 September only, with general admission from 11:00 to 23:00 and last booking at 21:00. Outside that window the facility is closed and the mountain road that reaches it is generally shut by snow.

How much do the Highland Baths cost?

On-site admission is ISK 5,500 for adults and ISK 900 for children aged 0 to 11, and it is included for overnight guests at Highland Base. A bookable two-hour admission is listed from $44, rated 3.5 from four reviews.

Do you need a four-wheel-drive to reach Kerlingarfjöll?

The standard route is the Kjölur highland route, F35, which is a mountain road. You need a vehicle your rental agreement permits on F-roads, typically a four-wheel-drive, and you should check the Road Administration's live mountain-road map on the day of travel, since openings depend on weather and snowpack.

Why does the Highland Baths rating look low?

The bookable listing carries 3.5 from four reviews, a very small base in which a single new review can move the average by a wide margin. The score reflects limited review volume at a facility open only fifteen weeks a year, not a settled verdict from thousands of bathers.

What can you visit instead when the Highlands are closed?

Secret Lagoon at Flúðir, Laugarás Lagoon on the Golden Circle route, Laugarvatn Fontana on the lake shore, and Reykjaböð in Hveragerði all stay open year round on paved roads. Laugarás and Reykjaböð are the newest of the set, opened in 2025 and September 2026 respectively.

Is there a remote soak that does not need an F-road?

Yes. Húsafell Canyon Baths in west Iceland pairs a short guided highlands hike with two geothermal pools and a cold spring, runs year round, and is bookable from $76. The booked slot is the only access, as there is no walk-up gate.

Want A Golden Circle Soak You Can Book Any Month?

Laugarás Lagoon sits on the Golden Circle route and stays open year round, with three ticket tiers and a two-course meal option. Checking the live listing takes a minute and shows current dates and prices for your travel window.
