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. The day passes require previous experience and do not include harness rental. 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!
