The period around Iceland’s solar eclipse on 12 August sent bookings for both the Blue Lagoon and Sky Lagoon to their highest levels of the summer season, with many date slots selling out within hours of becoming available. The rush has eased, but availability for August remains tight and the booking picture for September is uneven.
Here is what the current situation looks like and how to approach planning a visit.
Blue Lagoon availability
The Blue Lagoon operates a strict time-slot system with entry distributed across multiple windows throughout the day. As of late August, the 9:00–11:00 entry slots are the most likely to show availability for immediate dates; afternoon and evening slots sell out faster because they combine with sunset and lava field photography. The Blue Lagoon’s website allows bookings up to three months ahead, and weekday slots (Monday to Thursday) consistently offer more options than weekends.
If you are in Iceland now and hoping to visit within the next few days, check the booking portal each morning between 08:00 and 09:00 Reykjavik time — this is when cancelled reservations are most likely to be re-released.
Lava Restaurant within the Blue Lagoon complex books independently of the spa entry and follows a separate release schedule. Table availability is generally easier to find than spa slots in the two weeks following peak demand periods like the eclipse.
Sky Lagoon availability
Sky Lagoon in Reykjavik operates on a similar advance-booking system but has a smaller total capacity, which makes sold-out periods more common. The good news is that late August and September weekday afternoon slots have been opening up as eclipse-era bookings from visitors who have now left Iceland begin to lapse.
The Sky Lagoon’s Skjól all-access package — which includes the seven-step ritual — sells out faster than the Sér tier. Both packages use the same pool; the difference is the changing room experience and access to the ritual area.
For travellers based in Reykjavik, Sky Lagoon is the more convenient option: it sits on the Kársnes peninsula roughly 15 minutes by taxi or Strætó bus from the city centre. Our things to do in Reykjavik guide covers how to get there without a car.
September is a realistic window
The second half of September is shaping up to be one of the more accessible periods for both facilities. The eclipse-driven visitor spike has passed, the main August school-holiday cohort has departed, and the northern lights season is beginning — which draws a different type of visitor who is not always prioritising spa time.
For travellers with date flexibility, targeting arrivals after 10 September gives the best combination of slot availability and reasonable weather. The geothermal experience is arguably better in cooler temperatures: the contrast between the warm water and the autumn air is more pronounced, and the steam hangs above the lagoon longer.
