Mill Creek offers steep, fingery and powerful climbing on well protected sport routes. All the routes are located on one large boulder composed of a polished conglomerate rock. Although short the climbs will test your finger strength. The climbs can be dusty depending on the time of year.
Drive Highway 38 from Redlands heading East. Drive through Mentone, and follow the 38 past the Ranger Station (pick up an Adventure Pass here if you don't have one). Continue along the 38 for 3 miles until you see a sign for Thurman Flats Picnic Area on the right. Park here and follow the trail down to the river where the large boulder can be clearly seen on the other side of the river.

The easiest, by far, route here. The climbing starts easy enough up the obvious corner at the left side of the East Face.After a couple of ledges the climb gets surprisingly steep. Using an obvious undercling it is possible to gain a large hold. Make a couple more moves up to the anchors....[more] Browse More Classics in CA
