Build my planRattler was designed to showcase the stunning trails of Palmer Park, one of Colorado Springs' top city parks. Runners will enjoy panoramic views of the city below and the iconic Pikes Peak in the distance. As they navigate the singletrack, sandstone bluffs and unique rock formations rise around them.
