Sky Lagoon — Reykjavík's oceanfront geothermal spa

What Sky Lagoon is

Sky Lagoon opened in 2021 in Kársnes Harbour, Kópavogur — a suburb directly south of Reykjavík, about 7 kilometres from the city centre. It is a purpose-built geothermal bathing facility designed around an infinity-edge pool looking directly out to the North Atlantic Ocean. The location gives it genuinely dramatic views on clear days: the Snæfellsnes glacier is visible to the northwest, Reykjavík’s skyline to the northeast, and open ocean to the south and west.

The facility draws on Iceland’s geothermal infrastructure — the water is heated geothermally and maintained at 38–40°C year-round. Unlike the Blue Lagoon (which uses industrial discharge water), Sky Lagoon uses freshwater from the geothermal system. The water is clear rather than milky-blue; the aesthetic is clean and modern rather than volcanic-industrial.

Sky Lagoon is directly relevant to visitors staying in Reykjavík who want a geothermal bathing experience without the logistics of going to Keflavík or Grindavík. It costs significantly less than the Blue Lagoon, is operationally simpler, and has the practical advantage of being close to the city.

Ticket tiers in 2026

Sky Lagoon offers two main tiers:

Sér Pass (roughly €45–€55): Access to the lagoon and the Sky Lagoon changing rooms (“Sér” means private in Icelandic). This includes a private changing room rather than a shared changing area, a Sky Body Scrub product, and use of all pools and the sauna. The Sér Pass does not include the 7-step ritual.

Saman Pass / Pure Pass (roughly €65–€80): The main selling-point ticket. Includes access to the lagoon, the 7-step ritual spa experience (see below), a shared changing area, and towel. A private changing room version of this is also available at higher cost.

Children’s pricing and off-peak discounts exist — check the official Sky Lagoon website for current rates. As with the Blue Lagoon, advance booking is strongly recommended; slots can fill up, particularly in summer evenings.

Sky Lagoon Pure Pass with 7-step ritual

The 7-step ritual

Sky Lagoon’s main differentiator from other Icelandic pools is the structured 7-step experience offered with the Saman/Pure Pass. The steps move you through different thermal experiences:

1. Lagoon — soak in the infinity-edge geothermal pool (38–40°C)
2. Cold plunge — a cold pool for circulation contrast (~3–6°C)
3. Sauna — a large glass-fronted sauna with ocean views, typically 80–90°C
4. Cold fog mist — a fine cold mist in a dedicated area
5. Steam room — a warm steam room with herbal scent
6. Sky Body Scrub — exfoliating salt scrub applied in a dedicated scrub area
7. Shower and warm shower — rinse cycle with warm water

The sequence is designed to follow Nordic bathing tradition: heat, contrast, heat, contrast. In practice, most guests do the full sequence in 60–90 minutes, then return to the outdoor lagoon for additional soaking time. The full visit including preparation and changing typically runs 2–3 hours.

The sauna at step 3 is consistently cited as the highlight. It is a large space (30–40 people comfortably), the glass wall looking out to the ocean creates a striking visual, and the temperature is genuinely hot rather than the mild saunas common in hotels. The cold plunge pool is cold in the Icelandic tradition — not watered-down cold, but properly uncomfortable for 30 seconds, which is the functional value.

Views and location

The infinity edge of the main lagoon faces southwest over the North Atlantic. On clear days, this is legitimately impressive — the pool appears to extend directly into the ocean, and the horizon stretches unobstructed. In summer, evening visits capture long golden-hour light; in winter, northern lights occasionally appear overhead when conditions allow.

The Kársnes Harbour location is less photogenic from the outside than the volcanic setting of the Blue Lagoon, but the view from within the water is Sky Lagoon’s stronger asset. This is the comparison that favours Sky Lagoon: the volcanic setting of the Blue Lagoon is more dramatic approaching the facility; the actual view from the water is arguably more open at Sky Lagoon.

Sky Lagoon vs Blue Lagoon

For visitors who want one geothermal spa experience, the choice between Sky Lagoon and Blue Lagoon is the most common practical question. Both offer warm geothermal water, good facilities, and a distinctive Icelandic atmosphere. The meaningful differences:

Price: Sky Lagoon is roughly 30–40% cheaper at comparable tiers.

Location: Sky Lagoon is 7 km from central Reykjavík (accessible without a tour bus). Blue Lagoon is 50 km away and requires a dedicated journey (or combining with KEF Airport transit).

Water: Blue Lagoon water is silica-rich and milky-blue with known skin-effect properties. Sky Lagoon water is clear geothermal water.

Setting: Blue Lagoon sits in a black lava field — dramatically volcanic. Sky Lagoon has ocean views but a more modern, designed environment.

Crowds: Both attract significant numbers in peak season. Sky Lagoon’s capacity management is stricter; it feels slightly less crowded in absolute terms.

The 7-step ritual: Sky Lagoon has a structured wellness sequence; Blue Lagoon’s silica and algae masks are the equivalent. Both are optional extras beyond simply soaking.

The blue-lagoon-vs-sky-lagoon guide covers this comparison in more detail. For most visitors staying in Reykjavík, Sky Lagoon is the more practical and cost-effective choice unless you specifically want the Blue Lagoon experience or are transiting through KEF Airport.

Sky Lagoon admission with transfer from Reykjavík

Getting there from Reykjavík

By taxi or ride-share: 15–20 minutes from central Reykjavík; typical cost 2,500–3,500 ISK (€17–€24). The most flexible option if you want to control timing.

By bus: Strætó bus line 35 runs from central Reykjavík to stops near Sky Lagoon (allow 20–30 minutes). An all-day Strætó pass (2,600 ISK / €17.70) covers all bus travel including this connection.

By organised transfer: Several tour operators offer Sky Lagoon tickets bundled with round-trip transfers from Reykjavík hotels. This is convenient if you don’t have a car or want to manage the logistics in one booking.

By car: Free parking at Sky Lagoon. Drive south from central Reykjavík on Route 40 (Kringlan roundabout direction) toward Kársnes Harbour; Sky Lagoon is signposted. 10–15 minutes in normal traffic.

The facility opens daily from 10:00 (or 09:00 in summer peak months). Last entry times vary by season; check the official website.

Combining Sky Lagoon with other activities

Sky Lagoon pairs well with:

• A Reykjavík day trip returning via the lagoon in the late afternoon
• A south coast day trip with an evening at Sky Lagoon on return to Reykjavík
• The reykjavik-48-hours itinerary where it makes a natural second-day activity
• A videy-island ferry trip followed by Sky Lagoon (Videy ferries depart from Skarfabakki, about 2 km from Sky Lagoon)

Practical notes

Hair: Unlike the Blue Lagoon, Sky Lagoon water does not cause the same silica-buildup hair issues. Standard shower facilities with conditioner are provided.

Swimwear: Required; available for rental if you forget to bring one (approximately 1,000 ISK / €7).

Food and drink: Sky Lagoon has a bar (Gelmir Lagoon Bar) accessible from the water and the Smakk Bar cafe serving Icelandic small plates inside. Budget around 2,500–4,500 ISK (€17–€31) for a light meal. The bar in the water is a functional amenity, not a drinking destination — it serves drinks at standard Icelandic bar prices (1,500–2,200 ISK / €10–€15 for beer or cocktails).

Photography: The infinity edge and ocean view make for good photographs. Staff request discretion in changing areas. Waterproof phone cases are helpful for shots from the water.

Dining and food at Sky Lagoon

Smakk Bar inside the facility serves Icelandic small-plate food — plokkfiskur (fish stew), skyr parfait, lamb sliders, and skewer dishes. A meal of 2–3 plates typically costs 4,500–7,000 ISK (€31–€48) per person. The food is competently prepared; it is not a destination restaurant but it is better than generic spa café food.

Gelmir Lagoon Bar is accessible directly from the water and serves drinks in the lagoon. Beer, wine, and cocktails cost approximately 1,500–2,200 ISK (€10–€15). For a proper drink in the water (in the Icelandic outdoor-bathing tradition), this is where to get it. The view from the bar toward the ocean is the same good view from the lagoon — you’re not missing anything by ordering drinks at the bar rather than from the water.

If you plan to eat a proper meal, the restaurants in central Reykjavík are more varied and generally not significantly more expensive. Sky Lagoon is well-suited to a drink in the water followed by dinner in the city.

Photography and social media

Sky Lagoon is structured in a way that makes certain photographs straightforward. The infinity edge facing the ocean produces the classic promotional image — the wide-horizon shot with blue-grey water and the sky. This image is achievable in good light from the lagoon’s western section.

The sauna’s glass wall looking out to sea is a second strong photograph. There are modest queues for this shot at peak times.

Staff request courtesy around other guests in the changing areas and ritual rooms. The facility does not prohibit photography in the main lagoon or sauna, but the shared space means photographing without capturing other guests requires some patience or an early/late visit time.

The surrounding Kársnes area

Sky Lagoon sits in Kársnes Harbour, a developing mixed-use maritime area in Kópavogur. The immediate surroundings include the harbour, a boat yard, and developing residential/commercial buildings. It is not a scenic approach. The visual impact is entirely internal — once you’re at the lagoon’s edge looking southwest, the urban context disappears.

The drive from central Reykjavík takes you through residential Kópavogur suburbs, which are unremarkable but fine. There is no interesting area to walk around before or after the lagoon visit in Kársnes itself; pair it with central Reykjavík activities rather than expecting the surroundings to add to the day.

Accessibility notes

Sky Lagoon has been designed with accessibility considerations. The main lagoon and changing areas are step-free. The cold plunge pool requires stepping down, which may be difficult for some visitors; it can be skipped in the ritual sequence. The sauna benches are accessible at lower levels. Contact Sky Lagoon directly for specific mobility or sensory accommodation requirements before booking.

Children under 12 are not permitted in the Sky Lagoon geothermal pool or ritual areas. This is a firm policy that applies to all ticket tiers. Plan accordingly for family trips.

Sky Lagoon in summer versus winter

The experience differs meaningfully by season. In summer (particularly June and July), the sky doesn’t fully darken — visiting at 20:00 means bathing in long golden-hour light over the ocean, which is a legitimately different atmosphere than a standard spa visit. The midnight sun period (mid-June) creates an extraordinary light quality in the evening hours. On the clearest evenings, the Snæfellsnes glacier is visible to the northwest from the lagoon’s edge.

In winter, the dynamic reverses: arrive after 16:00 on a clear night and you’re bathing under a dark sky with aurora potential. The Sky Lagoon’s oceanfront location has produced northern lights photographs that have circulated widely — the aurora over the open sea viewed from a warm lagoon is an unusual combination. That said, cloud cover is the primary limiting factor, and Reykjavík-area skies are often overcast in winter. Don’t plan a trip specifically around this possibility, but appreciate it as a bonus if conditions allow.

The temperature contrast of the 7-step ritual (hot sauna, cold plunge) is arguably more satisfying in winter when the ambient air is genuinely cold. The cold plunge at −2°C ambient temperature is a more intense experience than the same pool at 15°C.

Frequently asked questions about Sky Lagoon

Is Sky Lagoon better than the Blue Lagoon?

Depends on your priorities. Sky Lagoon is cheaper, closer to Reykjavík, and has excellent ocean views. The Blue Lagoon has a more dramatic volcanic setting, the silica-rich water has distinct skin properties, and it is more convenient for KEF Airport transits. See blue-lagoon-vs-sky-lagoon-compare for the detailed comparison.

Do I need to book in advance?

Advance booking is strongly recommended — Sky Lagoon operates with timed entry slots and popular evening sessions fill up. Book at least 1–2 weeks ahead in summer, and a few days ahead in shoulder season. Same-day booking is occasionally possible but not reliable.

What is included in the Pure Pass?

The Pure Pass (Saman equivalent) includes lagoon access, the 7-step ritual (cold plunge, sauna, steam room, scrub, fog mist, showers), a shared changing area, and a towel. It does not include food, drinks, or a private changing room (those are available as upgrades).

Can I visit Sky Lagoon without the 7-step ritual?

Yes — the Sér Pass offers lagoon access and private changing rooms without the full ritual sequence. However, most visitors find the ritual is the main differentiator from a standard municipal pool, and the price difference is not enormous. Unless you specifically prefer to soak without the structured sequence, the Pure Pass is generally the better value.

What should I do if the lagoon is crowded?

Sky Lagoon can feel crowded in its sauna and ritual areas during peak times (July–August, evening slots). Arriving for the first slot of the day (10:00) or booking a late-afternoon weekday slot reduces congestion. The outdoor lagoon itself has enough space that it rarely feels uncomfortably busy.

Is Sky Lagoon suitable for children?

Children are permitted but Sky Lagoon is primarily designed as an adult wellness experience. The cold plunge and sauna are part of the main circulation path. Children under 12 are not allowed in the Sky Lagoon geothermal pool area. Check the official age policy before booking for family trips.
