Castle Rock is known for its community feel and year-round community events. It has become a destination spot for many Coloradans with the Outlet Mall, and the new addition of “the MAC” which has trails, zip lines, stair climb, an indoor pool, an amphitheater with concerts, and soon to be added year-round snow tubing and conference center! Castle Pines is located on the north end of Castle Rock, known for its rolling hills, Mature pine trees, and award-winning schools.
