Nearby springs
Glenwood Hot Springs Resort
A large downtown resort built around the Grand Pool, which stretches more than two city blocks, plus a 104°F therapy pool. The newer Yampah Mineral Baths add three hot pools between roughly 95 and 104°F and two cold-contrast baths, and that area turns adults-only after 5 pm. Day passes are sold without reservations, and the resort runs two hotels on site.
Yampah Spa & Vapor Caves
A spa built over natural underground steam caves heated by a 125°F geothermal spring, with three rock chambers that run around 110-113°F. Cave time is bundled with spa treatments and must be reserved ahead. Swimsuits are required and visitors must be at least 13.
Avalanche Ranch Cabins & Hot Springs
A cabin ranch in the Crystal River Valley south of Carbondale with three tiered natural pools, the largest fed by a small waterfall in front of a rock grotto. Day visitors book 4-hour slots in advance, while cabin and wagon guests have round-the-clock access. Pools are drained and cleaned every Wednesday.
