Williamson Rock is currently closed to climbing. Details


Sustained 5.8 climbing with no real crux, this route is solid for the grade, and will likely present a significant challenge to the entry-level 5.8 leader. Juggy, but overhanging, the climbing necessitates solid technique to keep the pump at bay. The route rewards climbers who can backstep and keep their center of gravity in close to the wall, but relentlessly punishes those who try and pull themselves up with their arms.


Locate "Shroomin'" on the downstream side of the boulder. "Mushroom" is the first route to its right. Alternatively, locate the waiting line at the base of the boulder and just get in line.


5 bolts to sport anchors. This is a very popular route. Watch for worn anchors.

The fa was done by Sam Owings.

The route saw numerous acsents including a couple of solos. Several years later it was bolted and climbed by a large group of local climbers. Mar 26, 2007

It's often great fun to watch people pump out and scream "TAKE" on this route. Happens again and again Mar 20, 2007

A fun, and fairly steep, warm-up climb that's easily accessible, but four stars seems a little enthusiastic for a thirty foot piece of rock. If this gets four stars then the route "Being There" gets about ten stars! Mar 19, 2007
