Book the Blue Lagoon online in advance (from ISK 11,990 in 2026), pick a time slot with a buffer around your flight, condition and tie up your hair, keep your wristband safe, and agree on a meeting point before you go in. Here are the 11 things we wish we'd known before our February 2018 visit, updated with 2026 prices, hours and rules.
1. It's 20 Minutes from the Airport
The Blue Lagoon is near Keflavík Airport, so most people visit on their first or last day. It was our first stop, as we landed in the afternoon. Many visitors combine it with an airport transfer.
2. Book Online in Advance
Pre-booking is essential: you choose an entry time slot, and popular slots sell out. Leave a buffer for flight delays and car rental pick-up; it's no fun missing your slot. Book direct on bluelagoon.com, which offers a best-price guarantee and lets you manage your booking online.

3. Prices Change by Time Slot
Prices for each hour change with demand. In 2018, an off-peak basic ticket cost ISK 6,900 instead of ISK 9,900 at peak times. Early-morning and late-evening slots are usually cheaper and quieter, and the busiest hours are around 10am to 2pm. Your slot is only your entry time: once you're in, you can stay as long as you like until closing.
4. Packages in 2026
| Comfort (from ISK 11,990) | Entry, silica mud mask, towel, toiletries, locker, one non-alcoholic drink |
|---|---|
| Premium (from ISK 14,990) | Comfort plus a drink of your choice, two extra masks, a bathrobe and a mask to take home |
| Signature (from ISK 18,490) | Premium plus a second drink and Blue Lagoon skincare products to take home |
| Retreat Spa | Five hours in the separate luxury spa, a private lagoon and changing rooms |
In 2018, packages were Basic (from ISK 6,900 off-peak), Premium (ISK 12,900) and Luxury (ISK 71,000). We bought the basic one, and it was good enough.
5. Towels Are Now Included
In 2018, the basic ticket didn't include a towel or robe, so we told readers to bring their own. Good news: every ticket now includes a towel, and Premium and above add a bathrobe. Shower gel, shampoo and conditioner are provided. Bring flip-flops if you like; the floors are wet and cold.
6. Shower and Use Conditioner Before You Go In
Everyone must shower before entering the lagoon, and staff check at the changing room exit. Use the conditioner generously and leave it in your hair: the silica and minerals dry hair out.
7. Tie Up Your Hair
Unless you want frizzy hair for a week! I left my hair ties in the car and paid the price. Even with conditioner, the lagoon water made my hair stiff. Keep your hair out of the water if you can.
8. Agree on a Meeting Point
The entrance to the lagoon is right after the changing rooms, and men and women change separately. If you're not taking your phone into the water, agree on a meeting spot first. We didn't and ended up waiting for each other in different places. There's now a marked meeting point where the changing rooms open onto the lagoon.
9. Don't Lose Your Wristband
At check-in, you get an electronic wristband that locks your locker and pays for drinks and extras. If you lose it, you'll have to pay, and it's easy to lose: we saw people searching for theirs in the water. Fasten it tightly and check it now and then.
10. The Silica Mud Mask Is Free
Every ticket includes the silica mud mask at the in-water mask bar. Extra masks, like the algae mask, come with Premium or can be bought. We wish we'd known to bring our own sheet mask to use after the silica mask!
11. Stay Hydrated
The water is 37–40°C, and it's easy to get dehydrated. Drink water before you go in, and use the water fountains and the indoor refreshment bar. The in-water bar sells smoothies, juices, beer and wine; your included drink is served there too.
Visiting with Kids (2026)
- Minimum age is 2. Children aged 2–13 enter free with a paying adult.
- Children aged 2–8 must wear armbands, provided free at the lagoon.
- One adult can supervise at most two children unless they're the parent.
- The water is up to about 1.3 m deep, so keep little ones within arm's reach.
