Hrunalaug Hot Spring is a geothermal bathing site near Flúðir in South Iceland. Three tubs stand outdoors: two larger ones and a small one for two people, holding about 30 bathers between them. The water runs at roughly 36–39°C and nothing is added to it. A rebuilt changing house beside the pools has heated rooms, code lockers, warm showers and toilets. Towels are rented on site, and coffee, drinks and snacks are sold at the hut where you pay.

What makes it special
Three geothermal tubs stand outdoors near Flúðir. Two are larger; the third takes two people. The water runs between roughly 36°C and 39°C, and the tubs differ, so you move until one suits you. Anyone used to a 42°C bath will find Hrunalaug cool. Nothing is added to the water, which is why everyone rinses off before getting in. The changing house beside the pools has been rebuilt: heated rooms, separate men's and women's sides, and lockers you close with a code of your own. Between them the tubs hold about 30 people, so the place has a ceiling on how crowded it can get.
Good to know
- Shower before you get in. No chemicals are used in the water, and the rule is taken seriously here.
- There are no stalls. The three showers are open and you change in the open locker room; men's and women's areas are separate.
- Bring sandals. You walk outdoors from the showers to the tubs.
- Not step-free. The entrance and the car park are not adapted for wheelchairs; the toilet is.
- Towels are rented, not included. Snacks, coffee and drinks are sold on site.
Getting there
No bus runs to the spring, so almost everyone arrives by car. The car park is about 150 metres from the pools. You pay at the hut by the entrance, then walk roughly 50 metres to the tubs. The changing house with the lockers and showers stands right beside the water, and the last stretch to the tubs is outdoors.
Best time to visit
Better: early in the day, or the last hours before closing.
Avoid: the middle of the day.
The three tubs take about 30 people in all, so it does not need a crowd to feel full. One visitor arrived at 11:40 on a weekday and had the pools to himself for an hour before others trickled in. Evenings thin out again — at 9 pm in July there were two other families in the water.
