Nanitch › All spots › Hot springs in Washington
Washington's hot springs are concentrated in the Olympics and the Cascades, and a good share of them need a walk in. The map below is honest about which ones anyone has confirmed recently.
Visiting Washington? Undeveloped springs reward a little homework: read the access notes and the season before you build a day around one, and have a second choice — springs close, wash out, and fill up on weekends.
Washington's statute is RCW 9A.88.010, and the exposure has to be “open and obscene” and made knowing it is likely to cause reasonable affront or alarm: two elements, and nudity on its own supplies neither.
It is not drafted to reach ordinary, non-sexual nudity.
That is not the same as “it's legal here.” Counties and cities legislate separately, and whoever manages the ground, whether that is State Parks, the Forest Service, BLM, a county or a private owner, sets its own rules on top. Check the land manager for the spot you're actually going to.
Nanitch is a map, not a law firm, and none of this is legal advice. Rules change and enforcement is local, so if it matters, check with the agency that manages the land before you go. Statute last read August 2026.
These have a page here because somebody has been to them: curated by Nanitch, confirmed by a member, or written up with real access notes.
Named hot springs imported from OpenStreetMap that nobody has confirmed yet. They are on the map and in the app, and they get a page here the moment someone reports back from one, not before. Listing every one of them:
