Mill Creek offers steep fingery 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).
