Blue Lagoon
Iceland's most famous geothermal spa — touristy but worth doing once
About This Experience
The Blue Lagoon is the most visited attraction in Iceland, and that reputation comes with baggage. It's expensive, it requires advance booking, and you'll share the water with a lot of other people during peak hours. We knew all of this going in.
What we didn't expect was how good it actually is when you time it right. We booked the first slot of the day — 8 AM — and arrived to a nearly empty lagoon. The water is a surreal milky blue, heated to around 38-39°C by a nearby geothermal power plant. Steam curls off the surface in the cold morning air, the black lava rock frames everything, and for about an hour it felt genuinely peaceful before the crowds started building.
The silica mud masks are included with entry, and the swim-up bar serves drinks you can sip while floating. It's a manufactured experience, sure, but it's well-executed and the setting is undeniably striking.
What to Expect
The Blue Lagoon sits on the Reykjanes Peninsula between Reykjavik and Keflavik airport, which makes it easy to slot in on arrival or departure day. The facility is modern and well-maintained — changing rooms, showers, lockers, and a café are all included.
You'll shower before entering (without a swimsuit, Icelandic style), then walk out into the lagoon. The water temperature varies across the pool — some spots are warmer, some cooler. The main lagoon is large enough that you can find quieter corners even on busier days. There's a silica mud station, an algae mask station, and a waterfall you can stand under.
The Comfort package includes entry, a silica mud mask, a towel, and a drink. The Premium adds a bathrobe, slippers, and a second mask. We went with Comfort and felt that was plenty.
Practical Tips
- Book weeks in advance — slots sell out, especially morning times
- The 8 AM slot is significantly less crowded than midday; worth the early alarm
- Combine it with your airport transfer — it's only 20 minutes from Keflavik
- Comfort ticket is sufficient; Premium extras aren't essential
- Don't wear your favourite swimsuit — the silica can discolour fabric over time
- Condition your hair heavily before entering; the minerals are harsh on hair
- Lockers use electronic wristbands — the same wristband charges drinks to your tab
- Budget about 2-3 hours for the full experience including changing
- Current prices start around 9,990 ISK (roughly 70 EUR) for Comfort
- The on-site Lava Restaurant is good but pricey; eating in Grindavik is cheaper

Fagradalsfjall Volcano Trail
The Reykjanes Peninsula eruptions reshaped this landscape between 2021 and 2025 — walking across still-warm lava fields with steam rising from cracks is about as close to another planet as you'll get without leaving Earth.

Golden Circle
Iceland's most famous day trip links three heavy-hitters — a geyser that erupts every few minutes, a two-tiered waterfall that shakes the ground, and the rift valley where Vikings founded the world's oldest parliament.

Snæfellsnes Peninsula
They call Snæfellsnes 'Iceland in miniature' and it actually delivers — in a single day trip from Reykjavik, we drove past a glacier-capped volcano, a black church, basalt sea stacks, seal colonies, and a fishing village frozen in time.
