Rocky Mountain National ParkAt the edge of Rocky Mountain National Park, Grand Lake is the deepest natural lake in Colorado, dipping to 265 feet. Fed by high mountain runoff, the lake is clear and pristine. In the summer, you can rent a boat, bring your own or simply enjoy the gentle lapping of the waves from the sandy shore. Grand Lake connects with Shadow Mountain Lake via a canal, and just down the road is Lake Granby, the second largest body of water in Colorado.
Other interesting summer activities include guided tours of Chimney Rock National Monument, hot air balloon adventures and paddling, tubing or rafting along the San Juan River. In winter you can go dog-sledding, cross-country skiing, snow tubing and more at the Wolf Creek Ski Area, enjoy some brewery-hopping or simply relax in the natural Pagosa Hot Springs.
