The best saunas in Denver & Boulder
Last reviewed October 2026
On a farm in the foothills above Boulder, people climb out of a wood-fired sauna and into a cold stream. Down in Denver, the plunge might be a tub in a garden off North Ogden Street or a courtyard on Larimer. Either way, it is outdoors.
#1 · Puffin Sauna Club
Farm sauna with a cold stream · Boulder
The wood-fired sauna is parked on Yellow Barn Farm, a regenerative farm in the foothills between Boulder and Lyons. Shared sessions run an hour. Between rounds you pick a Japanese-style cold plunge, an outdoor rain shower or the cold stream itself.
