Stopping at Glenwood Hot Springs after a snowy day on the Western Slope is part of Coloradans’ DNA. After all, that red sandstone bathhouse and vast pool date back to the late 1880s—right after the town of Glenwood Springs itself was founded. As of this past August, though, the grande dame has a little competition.
About a mile west, also on the bank of the Colorado River, the new Iron Mountain Hot Springs complex (day pass, $20; 281 Centennial St.) divides to conquer, offering 16 pools, all fed by the town’s 122° waters. And the park-style bathhouse, all shingles and slate, adds just the right rustic note.
