Public hot springs in California are not bathing facilities and do not have ‘plumbing’ like that of commercial, improved hot springs.
Soap and shampoo, including bio soap and shampoo, do not break down naturally and pollute our fragile ecosystems.
FYI, this is also illegal in most wilderness and public lands areas. Please report suspicious activity to public lands officials (take pics).
It is important to remember when visiting hot springs in California or any state to leave them in better shape than when you arrived.
Please leave no trace, bring no glass and embrace the experience.
We recommend cleaning up the area and hot springs before soaking as it makes for a more natural experience and reward for your stewardship efforts.
