Boulder Hot Springs is a large hot springs resort that was built in 1888. Natural hot mineral water is piped into several pools. There is an outdoor pool along with gender-segregated indoor pools. Swimsuits are required in the outdoor pool, but swimsuits are optional in the indoor men's and women's bathhouses. Each bathhouse contains a large hot pool along with a steam room. The women's bathhouse (but not the men's) has a cold pool as well.

The facilities are available on a day-use basis for a small entry fee (bring your own towel). Hours are from 10 am until 9 pm every day from April through October. Hours are much shorter during winter months. Call ahead to verify rates and hours. The resort also offers overnight lodging.
