Geothermal bathing at the foot of Reykjadalur
Reykjaböð combines an outdoor lagoon with a separate indoor Bathhouse on the edge of Hveragerði. It is in South Iceland, east of Reykjavík.
The dedicated opening-hours page confirms an opening date of September 5, 2026. Older FAQ sections still contain pre-opening language. Use current visitor information when planning a date, and contact the operator if the pages disagree about a facility you need.
The outdoor area includes warm water, sauna and cold-water facilities. The Bathhouse adds indoor rooms and pools with different heat and cooling experiences. Choose the setting you prefer and take the bathing sequence at your own pace.
The main difference between the two admission options is access to the indoor Bathhouse.

The entrance is at Árhólmar 5 in Hveragerði. Check the address separately from a general valley map point.
Travelers coming from Reykjavík use the Route 1 corridor toward Hveragerði. Traffic and conditions over Hellisheiði affect travel time. Leave room for the final approach through town and follow the facility’s entrance signs.
The operator provides on-site parking and asks guests to reserve designated accessible spaces. A private changing room with eight lockers also requires advance booking. A wheelchair is available for access toward the lagoon; confirm the route and assistance you need before arrival.
For public transport, use Strætó’s current journey planner and allow for the final journey from the Hveragerði stop to the entrance. A bus serving the town does not necessarily stop at the lagoon.

Allow about two to three hours for arrival, changing, showering, bathing and getting ready afterward. Allow extra time for a meal; check any time limit with your admission.
Visitor hours vary by season and holidays. The operator asks guests to leave the water before closing; check the current schedule before planning a late visit. Add time if you want a meal or additional facilities.
Shower thoroughly with soap and without swimwear before entering. Swimwear is required in the bathing areas. Follow the rules for each pool and sauna and take breaks from the heat when needed.
If a particular entry time matters, arrange it ahead of time; admission at reception depends on capacity. Keep weather and road conditions in mind for the return journey, especially during darker months.

Reykjaböð and the separate hot-river hike
Reykjadalur is a walking trip into the valley to a natural hot river. Reykjaböð is the managed bathing complex near town.
Choose Reykjaböð for changing rooms and a lagoon visit with limited walking. Choose the river when the hike and open valley are what you want from the day. Allow separate time for each if you intend to do both.
On a Golden Circle trip, Laugarás Lagoon, Laugarvatn Fontana and Secret Lagoon offer other bathing settings. Pick the one that best fits where you are staying and the rest of the route.
The Geothermal Energy Exhibition explains the area’s energy use, while Kerið adds a crater stop. Leave enough time to enjoy the soak before adding either. Read winter driving guidance before a late return and use Geysir as a separate Golden Circle stop.
