Cave Sauna Spa

This underground smoke sauna, heated pool and cold water pool are located near the sea.

Santalahti’s Cave Sauna Spa has a smoke sauna in a cave, a heated pool, cold water pool, changing room with a fireplace and a terrace. The arched caves open out towards the open sea to the south; therefore, the beautiful sea view can be admired from the heated pool while still under the arched ceiling.

The smoke sauna’s steam room, heated pool and fireplace room can each hold about 10 people. The recommended group size is no more than 20 people. For larger groups, it is a good idea to reserve the nearby Santa Glass Sauna and  2 VIP saunas, which can fit up to 60 people at one time.

The Cave Sauna Spa is the perfect place for a small company event. It is located at the Santalahti Resort, only 5 kilometres from Kotka in Southern Finland. We can also provide catering services for your group, and you can bring your own alcoholic drinks.

The large Lappish Shelter, the Fireplace Cabinet, the meeting Cabinet Luppi and the (2- to 18-person) holiday cottages (228 beds in all) are located close to the Underground Sauna Spa.

Soft steam is guaranteed!
