Swimming pools
Indoor and outdoor
Thermen Soesterberg has an abundance of water. You can choose from four large swimming pools, two indoors and two in the fresh air.
Our outdoor pools
Make the most of your visit and swim outside! The largest wellness swimming pool in the Netherlands can be found in the heart of our resort. It's the perfect spot for a refreshing swim or a lazy float. Quiet and sheltered, our smaller outdoor swimming pool is located on the edge of the resort, nestled against the treeline.
The water in both swimming pools is kept at a constant temperature of 32 °C, which makes for wonderful swimming in all weather and seasons.
Our heated indoor swimming poo
You can also enjoy two warm indoor swimming pools at the heart of the two sauna squares. A relaxing swim while enjoying stunning views in the newly opened wing is the perfect way to start your sauna circuit.
