Thermen Soesterberg

About

Thermen Soesterberg is a Therme-style wellness complex in the Netherlands offering a broad sauna and bathing experience with Finnish and steam saunas, multiple thermal pools, whirlpools, and daily aufguss ceremonies. The facility includes restaurants, spa treatments, yoga and wellness workshops, and an adjacent hotel for overnight stays. Visitors can book day passes or reserve spa services and retreat programs.

Good to know

• Runs aufguss sessions — a guided löyly ritual where an attendant fans the steam around the room on a schedule.
• Bar on premises — drinks alongside (or after) the session; the venue isn't dry like most outdoor sauna setups.
• Hot tub on site — adds a warm-water option between the sauna and the cold plunge for a longer cycle.
• Pool on site — works alongside the sauna for swim-and-sauna sessions or a longer cool-down between rounds.
• Restaurant on site — long sessions are the design; food is part of the visit rather than a stop on the way home.
• Pairs the sauna with spa services — massage, scrub, or other treatments — so a session can sit inside a wider visit.
• Set up outdoors — weather is part of the experience, so dress for the walk between cabin and water.
