With three great locations (Rockville, Columbia, Timonium), Earth Treks is your premier indoor rock-climbing destination. This pass is good for either two day passes or two open climb passes at any Earth Treks location. 

The Open Climb is the a great way to come in and try climbing. No reservations needed and no experience necessary! Open Climb Passes include up to 3 climbs and a free harness rental and are only available on weekends.
