High bidder will receive two certificates. Each certificate is valid for either two day-passes or two open-climb passes. An open climb pass includes three climbs, a harness rental, and an Earth Treks instructor to lead your climbing experience. This will give you a great taste of climbing - no experience is necessary! Standard Open Climb hours are Saturday and Sunday from 9 am - 5 pm. Visit the Columbia, Rockville, or Timonium location for this fun and energetic activity. If you're traveling out of town, visit Earth Treks in Golden, Colorado; better yet, visit the newest location at The Union Collective in Hampden-Medfield!
