The St. Leon Hot Springs, just North of Nakusp, are contained within a beautiful little stone pool in the forest (they require some hiking to reach).
Sadly, these hot springs are on private property and the current owners have made them inaccessible. However, the BC Hot Springs Preservation Society has a campaign underway to purchase the property so that these lovely hot springs will again be open to the public.
To learn more about this campaign or make a donation, see SavetheHotSprings.org.
