Williamson Rock is currently closed to climbing. MORE INFO >>>


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.

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!

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

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.

Ah, come on Chris, lighten up. "Mushroom" is a great little climb. Lots of interesting movement, where you need to focus on good technique and keep the hips in. The pump clock begins with the initial move. If "Mushroom" was as long as "Being There" it would get twenty-five stars.
