Imagine a real tropical oasis hidden deep inside a massive mountain. This is exactly what Grottebadet looks like—a unique water park in the city of Harstad, considered one of the most spectacular water complexes that northern Norway is proud of. Instead of the usual concrete walls, you are surrounded by rugged rocks transformed into cozy caves with waterfalls and warm pools.

This is a place where summer reigns year-round, regardless of the weather outside the underground complex. The facility is carved directly into the bedrock, creating an incredible "underworld" atmosphere. Visitors can find everything here: from swimming lanes for serious training to secluded jacuzzi areas for deep relaxation.
Thanks to its location right in the city center, Grottebadet has become a favorite vacation spot for both locals and tourists. It is not just a pool, but an architectural wonder offering guests a unique experience of immersion in warm water under ancient stone vaults, complemented by the modern Actic Training Gym.
