So I'm going to be in DC for a couple days in July and was wondering a couple things. 1. Is there any places to deep water solo in the area? 2. Any outdoor spots to boulder at? 3. And if there is any decent climbing gyms with an emphasis on bouldering?
2. Yes, some here. Also check MP's database for Caderrock (MD) and Great Falls (VA).
3. Yes. Earth Treks in Rockville. Huge bouldering area with tall walls. If you don't have a car, this place is still accessible by Metro transit.
My advice: see the city and enjoy it for what there is (the history, the architecture, the memorials, the Smithsonian, your tax dollars at work, etc). If you have an itch to climb, go to one of the two gyms that you can access via the Metro: either Earth Treks or Sport Rock. Don't waste your time searching for natural climbing that really isn't here in the first place.
