Eldorado Springs Pool & Artesian Spring

A genuine 1905 canyon resort fed by 6,000-year-old artesian water that runs a bracingly cool 76°F year-round, where daredevil Ivy Baldwin walked a tightrope 582 feet above the canyon floor 86 times between 1906 and 1948. The pool opens each Memorial Day and runs through Labor Day plus September weekends, still drawing crowds into a setting of red-rock cliffs.

The move: Drive the scenic road into Eldorado Canyon, spend the afternoon swimming laps in the cold artesian pool while the canyon walls tower overhead, then hike the short trail to see the anchors from Ivy Baldwin's tightrope wire before grabbing snacks at the on-site snack bar — arrive on a weekday to beat weekend crowds, or take the free Eldo Shuttle from Boulder for a car-free outing.
