Both are silica-rich geothermal pools in volcanic settings, both require advance booking in summer, and both sit among the best geothermal experiences in Iceland. The difference is largely geographic — the Blue Lagoon anchors the south, the Mývatn Nature Baths the north — and one is considerably more commercial than the other.

Location
Blue Lagoon: On the Reykjanes Peninsula, 48 km southwest of Reykjavík and 23 km from Keflavík International Airport. This makes it a natural stop at the beginning or end of most Iceland trips. The surrounding landscape is entirely black lava — no vegetation, extreme volcanic terrain — which forms a major part of the aesthetic.
Mývatn Nature Baths (Jarðböðin): In the Mývatn area of North Iceland, approximately 100 km southeast of Akureyri. Getting here from Reykjavík is a full day’s drive (around 450–500 km via Route 1, the Ring Road). Most visitors come through as part of a Ring Road itinerary, a North Iceland loop from Akureyri, or a fly-drive using Akureyri Airport. The Mývatn region has extensive volcanic activity — pseudocraters, lava fields, mud pots, and active geothermal vents — making the bathing experience part of a much wider volcanic landscape.
Price Comparison (as of 2026)
| Package | Blue Lagoon | Mývatn Nature Baths |
|---|---|---|
| Standard adult entry | ~ISK 9,990 | ~ISK 6,500 |
| Includes | Lagoon, towel, robe, silica mud mask, 1 drink | Lagoon and hot pots; towel rental separate |
The Mývatn Nature Baths are approximately ISK 3,500 cheaper per person at the base level. For a couple, that’s roughly ISK 7,000 (around £40) in savings. The Blue Lagoon base package includes more (robe, mask, drink), so the net difference narrows slightly if you value those inclusions.
Neither has a premium tier equivalent to the Blue Lagoon’s Retreat Spa (~ISK 44,990) — that level of spa experience only exists at the Blue Lagoon.
The Water
Blue Lagoon: The water’s distinctive milky-blue colour comes from its high silica content — a byproduct of the Svartsengi geothermal power plant. The silica forms a fine paste on the pool floor. Visitors apply the silica mud as a face mask directly from troughs in the pool. Water temperature holds at 37–39°C year-round across the main lagoon.
Mývatn Nature Baths: Also silica-rich, but the water here comes directly from a natural geothermal borehole at approximately 130°C, cooled before entering the pool. The colour is an opaque blue-green rather than the electric white-blue of the Blue Lagoon. Temperature is 36–40°C across the main pool and the two smaller hot pots, which tend to run slightly warmer. No mud masks — this is a soak, not a spa treatment.
Atmosphere and Crowds
Blue Lagoon: Iceland’s most visited single attraction. Capacity is managed through timed entry, but busy mid-session slots (10am–3pm) in July and August have a theme-park quality to them. The experience is polished and the facilities excellent — it’s just not quiet.
Mývatn Nature Baths: Significantly less crowded. The remote location naturally limits visitor numbers, and the pool capacity is smaller. On a summer weekday it’s possible to have large sections of the pool to yourself. The setting is more dramatic in some respects: the Mývatn lava landscape is actively volcanic, steam rises from the surrounding terrain, and you may hear (and smell) geothermal vents nearby.
What’s Around Each
Blue Lagoon area: The Reykjanes Peninsula is geologically active — Fagradalsfjall and Sundhnúkagígar have erupted repeatedly since 2021. The Bridge Between Continents (where you can stand on the rift between the North American and Eurasian tectonic plates) is 30 km away. Grindavík fishing town is 5 km east. This is the Reykjanes Geopark.
Mývatn area: One of Iceland’s most rewarding geologically active regions. The pseudocraters at Skútustaðagígar, the Dimmuborgir lava formations, the Hverir geothermal mud pots, and the Krafla caldera are all within 15 km of the baths. Combining the Mývatn Nature Baths with a half-day circuit of the Mývatn area is an easy and highly worthwhile combination.
Facilities
Blue Lagoon: Extensive. Full spa, LAVA Restaurant and Moss Restaurant, café, a spa retail shop, luggage storage, complimentary conditioner stations (essential — the silica dries hair), and the Retreat Lagoon for premium package holders.
Mývatn Nature Baths: A main pool, two smaller hot pots, changing rooms with lockers, a café serving snacks and drinks, and a gift shop. Comfortable but not luxurious. Towels are available for hire if you don’t bring your own.
Who Each is Best For
| Visitor type | Recommendation |
|---|---|
| First-time Iceland visitor | Blue Lagoon (iconic, widely referenced) |
| Arriving/departing Keflavík | Blue Lagoon (23 km from airport) |
| Ring Road traveller | Both — natural stops at each end |
| North Iceland base (Akureyri) | Mývatn Nature Baths (100 km away) |
| Budget traveller | Mývatn Nature Baths (~ISK 3,500 cheaper) |
| Seeking fewer crowds | Mývatn Nature Baths |
| Full spa day with food | Blue Lagoon (restaurant, premium packages) |
| Volcanic landscape experience | Mývatn Nature Baths (active volcanic surrounds) |
| Visiting with young children | Blue Lagoon (under-12 restriction at Sky Lagoon doesn’t apply here — both allow children) |
Recommendation
Choose Blue Lagoon if: You’re starting or ending your trip in Reykjavík or Keflavík, you want a full spa experience with food and premium options, or the Blue Lagoon has been a specific goal for your Iceland trip.
Choose Mývatn Nature Baths if: You’re driving the Ring Road and passing through North Iceland, you want fewer crowds, you prefer a wilder and more dramatic volcanic setting, or you’re using Akureyri as your North Iceland base.
Do both if: You’re spending a week or more in Iceland on a Ring Road loop. The experiences are different enough that doing both on the same trip makes sense — Blue Lagoon at the start (near the airport), Mývatn Nature Baths in the middle (Ring Road north).
Booking Details
Blue Lagoon: Book at bluelagoon.com. In summer, book 4–8 weeks ahead — the lagoon sells out. Walk-in entry is not available. First slot (around 8am) and evening slots (after 4pm) are quieter.
Mývatn Nature Baths: Book at jardbodin.is. Summer (July–August) advance booking is recommended. Walk-ins are more likely to succeed here than at the Blue Lagoon, but don’t rely on it during peak season.
