Two of Iceland’s best geothermal experiences outside the Blue Lagoon — one a sleek harbour-side spa a short drive from central Reykjavík, the other a raw volcanic pool in Iceland’s far north. Neither is a replacement for the other; they serve different trip profiles. Here is a direct comparison.

Location and Getting There
Sky Lagoon sits at Kársnes Harbour in Kópavogur, effectively on the southern edge of greater Reykjavík. It is the only major geothermal spa within practical reach of the city without a car. A dedicated shuttle runs from BSÍ bus terminal, and taxis from central Reykjavík take around 15 minutes. For visitors staying in the capital — particularly those on short trips or flying in and out of Keflavík — this is a decisive advantage.
Mývatn Nature Baths (Icelandic: Jarðböðin við Mývatn) are situated in the Mývatn area of North Iceland, roughly 100 km east of Akureyri and approximately 500 km north of Reykjavík along the Ring Road. Getting there requires either a rental car, a self-drive itinerary, or a guided tour departing from Akureyri. For Ring Road travellers, the Nature Baths fall naturally on the route between Akureyri and Egilsstaðir, making them a logical stop rather than a detour. For Reykjavík-only visitors, reaching Mývatn means a significant journey north.
Prices as of 2026
Sky Lagoon offers two packages:
- Skjól — approximately ISK 8,490 per person (around USD 62 / GBP 49). Includes full lagoon access, towel, robe, and the complete 7-step ritual.
- Sér — approximately ISK 11,990 per person (around USD 87 / GBP 69). Everything in Skjól plus a private changing suite.
Neither package is a standalone lagoon ticket — the 7-step ritual is built into the base price and cannot be skipped. Children under 12 are not admitted.
Mývatn Nature Baths charge approximately ISK 6,500 per adult (around USD 47 / GBP 37) for entry, which includes access to the main geothermal pool and the smaller hot pots alongside it. There are no structured ritual packages — the experience is open-format. Children under 6 enter free; ages 6–12 are reduced. A small café is on-site.
Mývatn is the cheaper option by around ISK 2,000 at the base level, with no upsell tiers.
The Experience: Designed Spa vs Natural Setting
These two attractions operate on fundamentally different philosophies.
Sky Lagoon is a purpose-built spa with clear architectural intent. The infinity-edge pool extends toward the Atlantic, and on clear evenings the view west over the ocean is genuinely striking. The surrounding structures use basalt stone cladding and open-air design to connect the facility to Iceland’s volcanic aesthetic. The 7-step ritual — lagoon, cold plunge, sauna, cold mist, steam room, body scrub, and warming area — is carefully sequenced and takes approximately 90 minutes to complete. The overall feel is refined: low lighting, curated playlists, consistent water quality, and a bar and restaurant on-site at Smakk Bar. It is a deliberate experience, designed to be one.
Mývatn Nature Baths are different in kind. The main pool is large and irregularly shaped, sitting amid a lava field with steam rising from the ground and the surrounding geological landscape fully visible. There is no structured ritual; you soak at your own pace in the geothermally heated water, moving between the main pool (approximately 36–40°C) and several smaller hot pots at varying temperatures. The milky-blue tint of the water comes from natural silica and mineral content drawn directly from the volcanic spring below. The sulphur scent is present but not overwhelming. Facilities are functional — changing rooms, showers, a café — without the spa-hotel ambience of Sky Lagoon.
Visitors who want a designed, sequenced experience with premium amenities should choose Sky Lagoon. Visitors who want to soak in geothermally active volcanic landscape with minimal infrastructure should choose Mývatn.
Crowds
Sky Lagoon has a capped capacity and sells timed entry slots online. In practice, this keeps the facility from feeling overwhelmed, and it is substantially less crowded than the Blue Lagoon. Weekend evenings in summer can feel busy; weekday mornings are the calmest. Book at least a week ahead in July and August.
Mývatn Nature Baths see their peak in July and August when Ring Road tourism peaks, but even in high season they remain quieter than any Reykjavík-area facility. Shoulder season — May, June, September — offers a noticeably calmer pool with the volcanic landscape in full autumn colour. Winter visits (November–February) offer the possibility of Northern Lights visible from the water, with visitor numbers at their lowest. Advance booking is still advised in summer but walk-ins are more commonly available than at Sky Lagoon.
Accessibility
Sky Lagoon is wheelchair accessible, with step-free entry to the pool and adapted changing facilities. The shuttle from BSÍ operates year-round and is accessible. Mývatn Nature Baths are also accessible with step-free pool entry, though the remote location and road conditions in winter require more planning for visitors with mobility requirements.
Both facilities require valid entry tickets and do not allow photography in changing areas.
Verdict
Sky Lagoon wins for Reykjavík-based visitors, those without a car, anyone who values a structured spa ritual and modern amenities, and travellers on short trips to Iceland. It is more expensive but more convenient and more polished.
Mývatn Nature Baths wins for Ring Road travellers, visitors already heading to North Iceland, those wanting a quieter and more natural setting, and anyone prioritising lower cost over facilities. The volcanic landscape around Mývatn is unique in Iceland and adds a dimension that no purpose-built spa can replicate.
If you are spending a week or more in Iceland and doing the Ring Road, both are worth visiting — they offer different enough experiences that there is no direct overlap. If you are limited to Reykjavík, Sky Lagoon is the clear choice.
