Biking is one of the best things to do in the summer. Telluride has a countless number of trails with a variety of levels, from a flat ride on the Valley Floor, to the thigh burning climb up Bear Creek Trail, or you could just ride around town on a townie cruiser. They have multiple options with different suspensions, and their fat tire bike is always a favorite. See if one would fit your needs, and rent one today.
Many different guided tours are available as well, for beginners and advanced riders alike. Explore old mining roads and single-track roads that climb to around 9,500 feet. Bootdoctors (800.592.6883) offers great mountain bike tours ranging from beginner to full day adventures. Their guides are well trained and every trip can be tweaked for your satisfaction.
