About
Little Dipper Sauna Co. parks two wood-fired trailer saunas on a working farm in the Driftless, outside Spring Grove. Community sessions run around a bonfire, a bucket shower and a cold plunge. One sauna has a clear roof panel for watching the stars.
Good to know
- Cold plunge available on site: use it between rounds for the classic contrast cycle.
- Mobile operator: the sauna travels, so the location is part of the booking. Check the current site before you arrive.
- Set in nature, away from the city, so bring a car or plan the transfer in advance.
- Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
- Swimwear sauna: some or all sessions are taken in swimwear, so pack it.
- Wood-fired heat: softer, heavier löyly than electric, and the smell of the stove is part of the room.
Hours
- Hours not listed
Community sessions are announced through the newsletter. Private farm parties by arrangement.
