Eldorado Springs, CO
Eldorado Springs Pool
The historic 1905 swimming pool at the mouth of Eldorado Canyon, reopened in 2025 after a full renovation, fed by the 6,000-year-old Eldorado artesian spring (heated to ~79-82°F in summer). Sandstone canyon cliffs, a grassy creekside lawn, diving board, snack bar and new beer garden make it a classic summer day trip from Boulder/Denver. In winter it runs limited ticketed 'Hot Spring Series' soaking events at 95-100°F.
