Description 

Great quality granite. Plethora of bouldering and top rope problems. A few lead routes as well. Certain spots can get crowded with groups, but the area usually affords plenty of route areas to avoid people if you wish.


Getting There 

Take Hwy 60 or Hwy 91 and go to Rubidoux. The mountain is the obvious granite boulder strewn one with a white cross on top of it. If approaching from the east, take 14th st. to Glenwood. Park just south on Glenwood, by the gate entrance and trail head (don't block the gate). If approaching from the west (Hwy 60), take the Mission Blvd. exit and head east. You'll see Mount Rubidoux on your right up ahead. You can then take Redwood (right) to 14th (right) to Glenwood (left) and park a block or two up it. Once you see the hill with the cross you can also park anywhere legal closer to the spot you wish to head.

Trapeze. photo by Chris Miller

Trapeze V0 4  CA : Inland Empire : ... : Half Dome Boulder
On the southwest side of the larger Half Dome boulder, climb up the vertical face on excellent rock. Use sidebulls, an undercling, and incut flakes near the top. Fairly OTD with a not-so-great landing, many might opt to set a toprope utilizing the same anchors that are used for the north face cracks. Warning: lizards live under the deep undercling and might startle you, although I've never had one bite me in what I imagine are probably more than a hundred ascents....[more]   Browse More Classics in CA
