  • See the driving instructions for Little San Gorgonio Peak. This route assumes that you are hiking each peak along this section of Yucaipa Ridge (5 peaks).


  • From Little San Gorgonio Peak, hike west along the ridge to a radio tower shown on the USGS topo map.
  • Continue west on a dirt road down into a saddle.
  • Continue west on the road until the road makes a sharp turn to the left.
  • Leave the road to the right and hike north up to the peak. This is a wide wooded area. The peak is not named on the topo but is shown as 8832'.


The route continues west down Yucaipa Ridge past Birch Mountain to the Allen-Birch saddle. This route crosses private property. You must obtain permission several days in advance to use this exit route.

The USGS topo shows a trail starting at Pilgrim Pines Camp in Oak Glen and going up to a point near Cedar Mountain. This trail crosses private property and must be used only with permission. We no longer (2010) have information on how to obtain this permission. Please contact the HPS Mountains Records Chair if you have those details, thanks!


This peak and the four nearby peaks are normally done together as a car shuttle trip. It is possible to descend the ridge from the saddle just east of Birch Mountain to the town of Forest Falls. See the Birch Mountain guide for additional information.
