Join REI, Earth Treks, and the Mid-Atlantic Climbers to celebrate climbing in our region! This full day party is for climbers of all ages, abilities, and disciplines. Are you craving to help preserve your local crag at a stewardship event? Longing to learn more about the history of climbing in the area? Ready to take the next step to climbing outdoors? If so, this event is for you! Test your skills in our festival-style climbing challenge. All participants will have the chance to win raffle tickets, courtesy of Earth Treks, for a free 1 month membership! Don't miss out on the REI raffle to win sweet gear! Or maybe you're looking to just chill, meet new people, eat food, and sip some beer? Enjoy free beer from Denizens Brewing (suggested donation benefiting MAC) and dinner from a few of DC's best food trucks (on our tab while supplies last). This event is open to all (not just Earth Treks Members)! A gym day pass is $25, and REI Members will get a free entry into the event! Mention the code REIROCKTHEBLOCK and show proof of your REI Membership to redeem this offer! Not sure if you're an REI member? You can look yourself up online by visiting
