Glen Canyon Mostly Bouldering 47 routes in crag

Many options, but the most straight forward for new visitors is to walk up through the canyon from the rec center end of the park (Elk St at Chenery - you'll walk up Chenery if coming from BART). Follow the gravel road north alongside Islais Creek or take one of the trails up the hillside to the right to get to the 'Hillside Boulders', 'Black Overhang' and 'Choss Buttress'.

The first boulders you'll see are the 'Hillside Boulders' up high on the right. Next are the 'Black Overhang' and 'Choss Buttress', also up to the right. Passing the preschool on the left you'll reach the "kung fu bridge" over the swamp. Legend has it that a famous Bruce Lee scene was filmed here, hence the name. After emerging from the willows, you'll see the 'Main Cliff Band' straight ahead up the hill; 'The Unnatural Act Cave' is partially obscured, directly above the 'Main Cliff Band'.

Please don't cut straight up the hill to the 'Main Cliff Band' - SF Rec & Park has spent a lot of time in recent years track building and stabilising the hillside, and the stairs leading up to the right double back straight to the crag, making shortcutting unnecessary.

'Dead Cat Rocks' is visible from the top of the 'Main Cliff Band', further up the canyon and on the opposite side of the creek. Climbing is prohibited here - please stay away to preserve good relations with SF Rec & Park. This outcrop is also overrun with poison oak, so pleasant climbing opportunities are very limited.
