2 Best Sights in Aspen and the Roaring Fork Valley, Colorado

Newer and more relaxing than its famed sibling across town, Iron Mountain Hot Springs is geared to adults looking for a peaceful retreat. Seventeen mineral pools with views of the Colorado River and Mt. Sopris are scattered across the hilltop; temperatures vary from 98°F to 108°F. A large family pool, heated to 94°F, encourages young children to stay out of the soaking spas, and soothing music drowns out much of the noise from the nearby kids' area. On-site bars offer a variety of beer and wine for sipping at the pools, and the contemporary locker rooms maintain the property's spa–like atmosphere. In summer 2023, a new adults–only area complete with two large pools with waterfalls and eight riverside pools lined with relaxation pebbles opened to visitors over 21. Reservations are required and visits are limited to three hours.

The majestic Maroon Bells, twin peaks more than 14,000 feet high, are so colorful, thanks to mineral streaking, that you'd swear they were blanketed with primrose and Indian paintbrush. It's one of the most photographed spots in the country, which is why reservations are required to ensure the view. Before 8 am and after 5 pm in the summer, cars can drive all the way up to Maroon Lake (though vehicles with children in car seats or people with disabilities are allowed to do so at any time). Otherwise, parking is available at the Aspen Highlands garage, where guided bus tours and shuttles leave regularly in summer months.
