Green Mountain (8,144') stands prominently over Boulder's iconic Flatiron formations and historic Chautauqua Park. The Mesa, Bear Canyon, Green-Bear, Ranger and Baseline trails form a challenging but exciting route up and around this sprawling mountain complex. Visitors will enjoy open space along the eastern foothills, miles of deep woods travel, and magnificent views from highpoints leading up to the Green Mountain summit.
