Iceland is famous for its geothermal hot springs, and two of the most iconic are the Blue Lagoon and the Mývatn Nature Baths. While the Blue Lagoon draws international crowds with its milky blue water and luxury spa treatments, the Mývatn Nature Baths offer a quieter, more rustic experience in the volcanic landscape of North Iceland. This article provides an honest, side-by-side comparison to help you decide which one fits your itinerary and budget. We cover location, cost, water quality, facilities, crowds, and practical tips — all based on widely known facts and official pricing as of 2025.
Location and accessibility
The Blue Lagoon is situated on the Reykjanes Peninsula, about a 20-minute drive from Keflavík International Airport and 50 minutes from Reykjavík. Its proximity to the airport makes it a popular stop for travelers arriving or departing. Many visitors book a session on their way from the airport or before a flight. The lagoon is well signposted and has ample parking.
The Mývatn Nature Baths (Jarðböðin við Mývatn) are located in northeast Iceland, roughly 6 km east of the town of Reykjahlíð on Lake Mývatn. They are about a 1-hour drive from Akureyri, the region's main hub. Most visitors come as part of a North Iceland itinerary, combining the baths with other attractions like the Mývatn geothermal area, Dimmuborgir lava formations, and Húsavík for whale watching. The baths are less accessible than the Blue Lagoon but well worth the detour if you are exploring the north.
Cost and pricing (2025)
Pricing is a major factor for budget-conscious travelers. Here are the standard adult admission prices (as of early 2025):
- Blue Lagoon: Comfort package (entry, silica mud mask, first drink, towel) starts at ISK 10,990 (approx. €75 / $80). Premium package adds a second mask, slippers, bathrobe, and sparkling wine at ISK 14,990 (€102 / $109). Retreat Spa packages are significantly higher, from ISK 29,990 (€205 / $220).
- Mývatn Nature Baths: Standard entry is ISK 6,500 (approx. €44 / $47). Towel rental is ISK 600, and bathrobe rental is ISK 1,200. There is no mandatory package system; you pay for what you need. A drink or snack at the café is extra.
The Mývatn Nature Baths are notably cheaper, especially if you bring your own towel and skip extras. For a family or solo traveler on a budget, the savings are significant. However, the Blue Lagoon’s packages include amenities that many find convenient, especially if you are traveling light.
Water quality and composition
Both lagoons are man-made but fed by natural geothermal seawater. The differences lie in mineral content and appearance.
Blue Lagoon
The water is a milky opaque blue due to high concentrations of silica, algae, and minerals. The temperature averages 37–39°C (98–102°F) year-round. The silica forms a white mud on the bottom and is used in the famous in-water masks. The water is sourced from the Svartsengi geothermal power plant, which extracts steam and hot water from deep wells. The lagoon is essentially the plant’s runoff, enriched with geothermal seawater.
Mývatn Nature Baths
The water is clearer with a light turquoise tint, containing less silica and more sulfur. The temperature is typically 36–40°C (97–104°F), with a hotter area near the source. The baths are also fed by water from the nearby geothermal power plant at Bjarnarflag. Because of lower silica, the water does not form the same thick mud, though there is a small silica mud pit available for masks. The sulfur smell is more noticeable than at the Blue Lagoon, which some find off-putting and others consider a sign of authenticity.
Facilities and amenities
Both sites offer changing rooms, showers (mandatory nude shower before entering), and lockers. However, the scale and luxury differ.
Blue Lagoon
- Large, modern complex with multiple changing room areas, including private changing cubicles for Premium guests.
- In-water bar serving smoothies, beer, wine, and cocktails (included in Comfort package for one drink).
- Silica mud mask stations where you can apply the mask while in the water.
- Sauna and steam room (included).
- Retail shop selling skincare products made from lagoon minerals.
- Restaurant Lava and a café offering Icelandic cuisine.
- Accessible for wheelchair users with pool lifts.
Mývatn Nature Baths
- Smaller, more basic facility with one main changing area.
- In-water bar serving a limited selection of drinks (beer, soft drinks, water) — not included in entry.
- Small silica mud pit (self-apply).
- Two steam baths (dry and wet) overlooking the lagoon.
- Café with light meals and snacks.
- No dedicated retail shop, though a small counter sells a few products.
- Wheelchair accessible, but fewer lifts.
If you prioritize luxury and variety, the Blue Lagoon wins. For a no-frills geothermal soak, Mývatn Nature Baths are perfectly adequate.
Crowds and atmosphere
Crowd levels are one of the biggest differences.
Blue Lagoon: Extremely popular, with daily visitor numbers in the thousands. Even with timed entry, the lagoon can feel crowded, especially during peak hours (10:00–15:00). The atmosphere is lively, with groups chatting, selfies, and a resort-like buzz. If you seek solitude, this is not it. Late evening or early morning slots are slightly quieter but still busy.
Mývatn Nature Baths: Quieter, with a more relaxed pace. Even in summer, the baths rarely feel overcrowded. The setting is open with views over the lake and surrounding volcanic terrain. Many visitors describe it as meditative. The lack of a strict time limit (you can stay as long as you like during opening hours) adds to the unhurried feel. In winter, the baths are especially serene, with steam rising into the cold air and possible northern lights.
Surrounding attractions and integration into your trip
Choosing between the two often depends on your overall itinerary.
Blue Lagoon area
The Reykjanes Peninsula has several sights: the Bridge Between Continents, Gunnuhver hot springs, and the volcanic landscapes of Fagradalsfjall (if erupting). However, many visitors go directly to the lagoon and leave. The lagoon is a logical stop on a complete Iceland itinerary if you are arriving or departing from Keflavík. It can also be combined with a day trip from Reykjavík, though that adds travel time.
Mývatn area
The Mývatn region is rich in natural wonders. Within a short drive are the pseudo-craters at Skútustaðir, the lava labyrinth of Dimmuborgir, the geothermal area at Námaskarð (Hverir), the powerful Goðafoss waterfall, and the Krafla volcano with its Víti crater. The baths fit naturally into a North Iceland week, especially after a day of hiking or exploring. Many travelers visit the baths in the late afternoon to soothe tired muscles. The nearby town of Reykjahlíð has accommodation and dining options, though limited compared to the Blue Lagoon area.
Which one is better for you?
There is no universal answer. Here is a quick decision guide:
- Choose the Blue Lagoon if: You have limited time near Keflavík or Reykjavík, want a luxurious spa experience with premium amenities, enjoy a lively social scene, or are willing to pay a premium for convenience and iconic photo opportunities.
- Choose Mývatn Nature Baths if: You are traveling the Ring Road and visiting North Iceland, prefer a quieter and more affordable soak, enjoy raw volcanic scenery, or want to combine the baths with other natural attractions in the Mývatn area.
Many travelers do both, especially on a longer trip. For example, you could visit the Blue Lagoon on arrival day and the Mývatn Nature Baths during your northern leg. However, if you only have time for one, Mývatn offers better value and a more authentic feel, while the Blue Lagoon delivers a polished, world-famous experience.
Practical tips for visiting
Blue Lagoon
- Book weeks or months in advance, especially in summer. Walk-ins are rarely available.
- Arrive 15–30 minutes before your slot to allow for check-in and changing.
- Bring a waterproof phone case or buy one at the shop (overpriced).
- Shower thoroughly without swimsuit before entering (mandatory).
- Apply conditioner after swimming to prevent hair damage from silica and minerals.
Mývatn Nature Baths
- Booking is recommended in summer, but winter often allows walk-ins.
- No time limit, so plan 1.5–2 hours for a relaxed soak.
- Bring your own towel to save rental fee. A bathrobe is optional.
- The changing rooms are smaller; avoid peak times (11:00–14:00) for more space.
- Visit after hiking in the area — the hot water soothes sore legs.
Conclusion
Both the Blue Lagoon and Mývatn Nature Baths offer unforgettable geothermal bathing, but they cater to different travelers. The Blue Lagoon is a bucket-list destination with a high price tag and crowds, while Mývatn Nature Baths provide a more affordable, peaceful alternative in stunning natural surroundings. Consider your itinerary, budget, and preference for solitude vs. luxury. Whichever you choose, you will experience Iceland’s geothermal magic.
