Introduction

Beautiful waterfalls that descend from between Middle Peak and Cuyamaca Peak in Rancho Cuyamaca to Boulder Creek.

Approach

From the east-topo shows parking area in Rancho Cuyamaca for hike along dirt road and ascent along dirt path. At around 5400' elevation, leave the dirt path and route find down to the first waterfall. This avoids private in-holding by staying on the right side of barb wire fence which has fallen along the way.

Descent

From the top, the route along the stream is dense with ceanothus, manzanita and large fallen trees that were destroyed in a fire. It may be very difficult to complete (see remarks below). From the west, the route crosses private property and is very difficult to follow. It is also choked with ceanothus, manzanita and acres of poison oak. Climbing the falls from the bottom is also difficult, but rewarding.

Exit

Ascend back up to avoid private property--I will post additional info shortly if another exit can avoid private property.

Red tape

Private property for approach from the west side. Private property if exiting via Boulder creek.

Trip reports and media

Descended lower falls 2/15 by climbing from bottom. Reached upper falls twice with ChristianL, but found it too hard to descend thru ceanothus and downed trees. Upper fall can be rapped w/o descending rest.
