opening in the spring of 2026
New Jarðböðin (Nature Baths) facilities
The new Jarðböðin (Nature Baths) facility at Mývatn is scheduled to open in the spring of 2026. The design of the building—both inside and out, along with the lagoon—has been shaped by the unique nature of the Mývatn area. The connection to the environment and the surrounding natural formations is reflected throughout the design.
The building, which is just under 4,000 square meters, is blended into the landscape, using local stones as roof ballast, roof edging, exterior cladding, interior walls, and terrazzo flooring. It will sit east of the current lagoon and be connected to it by a new lagoon formed around a tuff pillar island, a fissure, and lava-rock walls. Visitors will be able to walk directly into the water from the changing rooms and explore three different sections of the lagoon.
Major changes to the current lagoon
Two new hot tubs, a new and larger bar, expanded seating areas, and improved access to the steam bath. The new lagoon will add experiences such as a rock steam room you can swim into, a waterfall, a new lagoon bar, and a fissure/cave passage where guests will travel through the gap to reach a larger, more open part of the lagoon.
Package 1
The Basic Experience
Changing rooms are divided into sections for comfort and spaciousness. There are private showers, and guests can store towels/phones in a personal locker before entering the lagoon.
Package 2
The Core Experience
Access to the Lava Changing Rooms, where natural lava-rock walls form the exterior, and a lava wall divides the men’s and women’s areas. Guests walk through an impressive lava-walled corridor straight into the lagoon.
Package 3
The Tranquility Experience
A private changing room for two, with the option to order food and wine from the lounge’s menu. Access to a relaxation room and a private lagoon area exclusively for Tranquility guests.
Three different packages
The new building has been designed so that all guest facilities are as high-quality as possible. Visitors will be able to choose between three different access packages, each offering different changing rooms and experiences.
More space & a new bistro
With this new facility, around 580 guests can be accommodated at once—an increase of about 33% from the current capacity. The lagoon itself will also expand by roughly 35% in surface area. A new bistro offering fresh dishes made from local ingredients, along with a light menu, will be one of the new additions.
The dining area will seat 150 people, the same capacity as the current restaurant. The reception and restaurant open to the west with views over the lagoon and Lake Mývatn. An outdoor seating area will be available for bistro guests during the summer.
