Frequently asked questions

Which Blue Lagoon package should I choose?+
Three main packages: __Comfort__ (€80-100 depending on slot and season) includes entry, robe, towel, silica mask and 1 drink — the best value. __Premium__ (€130-150) adds a second mask (hydrating), premium robe, sandals, second drink and reserved table at LAVA. __Signature/Retreat__ (€300-500) gives access to the Retreat Spa (private lagoon, 4-hour ritual, hammam, sauna) — recommended for a honeymoon or anniversary moment. The Comfort package is more than enough for the vast majority of visitors.
Do I really need to book the Blue Lagoon in advance?+
Yes, absolutely. The Blue Lagoon operates only on pre-booked time slots online at bluelagoon.com — no walk-up sales. The most convenient slots (morning 8am-10am and late afternoon 5pm-7pm) routinely sell out 2 to 4 weeks ahead in high season (June-August), 1 week in low season. Book as soon as your travel dates are confirmed.
How do you get to the Blue Lagoon?+
Three options. __Hire car__: 20 min from Keflavík, 45 min from Reykjavik, free parking. __FlyBus shuttle__ (Reykjavik Excursions): from Reykjavik €30 return, from Keflavík €25 return, several daily departures — practical to combine airport-lagoon-Reykjavik with a single booking. __Organised tour__ (Gray Line, Iceland Excursions): Blue Lagoon + Golden Circle or Reykjanes combination day, €120-180/person with transport and entry.
Should I bring my own towel?+
No, the towel is included in all packages. The robe is included from Comfort onwards, sandals from Premium onwards. However, bring a swimsuit (mandatory, otherwise rental €8). Changing rooms are separated men/women, with individual lockers (electronic chip bracelet). __Mandatory naked shower before entry__ — strict Icelandic tradition to preserve water quality (individual cabins available if modest).
Is the Blue Lagoon water really beneficial for skin?+
Yes, clinical studies confirm positive effects on dry skin and psoriasis. The water is rich in __silica__ (which forms the white mask), in __blue-green algae__ (Cyanophyta, anti-inflammatory) and in __sulphurous minerals__. A specialised dermatology clinic (Blue Lagoon Clinic) offers 5-10 day treatments for severe psoriasis patients, with documented results. For an ordinary visitor, the effect is more cosmetic than medical, but the skin does emerge very soft after 2 h of bathing.
Is the Blue Lagoon worth its high price?+
Yes for the iconic experience, but no if you compare value with other Icelandic lagoons. The __Sky Lagoon__ in Reykjavik (€60-100) offers a more immersive 7-step ritual circuit. The __Mývatn Nature Baths__ in the north (€50-60) have an equally impressive setting and far fewer people. The __Secret Lagoon__ at Flúðir (€30) is more authentic. The __public pools (sundlaugar)__ of every Icelandic village (€8-12) offer the most local experience. For a first trip: do the Blue Lagoon for the icon, but also explore the alternatives.

Our verdict

The Blue Lagoon is a must-do experience at least once — for the iconic photo, for the dermatological virtues, for the wellness moment before or after a long flight. But it is not the most authentic geothermal experience in Iceland: if you want a more intimate and far cheaper setting, head instead to Sky Lagoon (Reykjavik, €60-100), Mývatn Nature Baths (north, €50-60), Secret Lagoon at Flúðir (€30) or the sundlaugar (public pools) of every Icelandic village (€8-12). Our tip for Blue Lagoon: book the slot just after your Keflavík arrival or just before your return flight, choose the Comfort package (the optimal price-quality ratio), arrive early (8am-10am slot less crowded) and plan 2-3 hours on site.
