Sundhöllin, located in the heart of Reykjavík, is a convenient swimming pool accessible on foot from most parts of the city, even for those renting a car for their stay. Iceland visitors with a Reykjavík City Card can enjoy complimentary entry to the pool and free or discounted access to various other attractions and services throughout the city.

Sundhöllin, Reykjavik’s oldest pool, has welcomed visitors since 1937 when it first opened as a public bath. After operating for decades, it finally underwent a major renovation in 2017, adding a range of new features while preserving its historic charm. Opening hours are 08:00 – 22:00 and it’s a very friendly cozy environment for family and friends.

While Sundhöllin holds the title of Reykjavik’s oldest pool, it isn’t Iceland’s oldest. That honor belongs to the Secret Lagoon near the village of Flúðir, which opened in 1891. Unlike Sundhöllin, however, the Secret Lagoon was abandoned for several decades before it was recently restored.

Designed by the renowned architect Guðjón Samúelsson, Sundhöllin shares its architectural heritage with some of Reykjavik’s most iconic landmarks, including the National Theatre, the University of Iceland, and the famous Hallgrímskirkja church, which is even visible from Sundhöllin’s sundeck.

Located on Barónsstígur, just a short walk from the city center and intersecting with the popular shopping street Laugavegur, Sundhöllin is well-placed for visitors. However, it remains a local favorite, frequented by residents more than tourists—though the abundance of nearby hotels and hostels makes it an easy alternative to the more widely known Laugardalslaug pool in eastern Reykjavik.
