Locally Owned Since 1987: The Portland Rock Gym has been turning Portlanders into climbers for 30 years. Our mission is to teach and train rock climbing indoors and out at the crags, as well as celebrate and preserve our local cliffs and boulders through community involvement. Our indoor climbing facility is located at 21 NE 12th Ave in Portland, Oregon, and our guide service can take individuals or groups out to the local cliffs that we played a key role in pioneering.
