In the US, an outdoor sauna is something you book rather than somewhere you drop in. Almost every venue here is private hire: you get the cabin or the barrel to yourself and whoever you bring along.
That is a real change from the UK and the Nordics, where you share the bench with strangers. These saunas are spread right across the country: the Pacific Northwest, the Great Lakes, the Northeast, and a scattering through the South.
In the United States, 14 of the curated saunas fit this cut. See the full the United States country guide for every venue, or keep scrolling for just the outdoor saunas.
