Hrunalaug is a charming hot spring tucked away near the Golden Circle and one of the most charming spots to soak. The rock-lined pools sit in a beautiful natural setting and feel quiet and peaceful, perfect after a long day of exploring. It’s less than a 5-minute walk from the car park to reach the pools. Visits are limited to 90 minutes to keep things relaxed, and the entrance fee is 3,000 ISK per adult..
