Nick Mierau bouldering in Mill Creek


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.

Although the climbing here is not the best in the area it is still a worthwhile destination if your are comfortable climbing 5.12a+.

Getting There 

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.

Take care crossing the river (a fallen tree can be used in high water conditions).

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

Hey spent sat (3/31) morning there some of the routes are infested with hornets. Letterly they are living inside some of the holds on a few routes. just a heads up. Be Careful.

This is a small but worthy local area with technical climbing on slick rock. As mentioned a great area for those climbing 5.12 and up.

In addition to the roped climbing there is some decent bouldering in the area, but watch out for broken glass!
