Cucamonga Peak topo map
From campus take Foothill or Baseline east to Euclid and turn north (left). Turn right on 19th. At Sapphire turn left and follow it up the hill to a "T". Turn left and immediately turn right again. Follow this road up the hill until the pavement ends. Only 4WD vehicles with high clearance can continue. Park and begin hiking or biking up the dirt road. To reach the stream turn left at the fork and follow the road down to the major stream crossing. The drive is about twenty minutes and the hike is about three miles round trip.
Cucamonga Canyon is a deep, shady canyon among a forest of chaparral. The creek is excellent for creek hiking and serious climbing potential exists after some work. A short ways downstream the first crag appears on the right. A bolted climb (about 5.8) sticks up on the right. Other climbs are possible on this small wall. Just past the crag on a side creek a sixty foot wall looks to have possible routes after some cleaning. Below these small outcrops the creek travels into some narrow rock canyons. The walls pinch together and form picture-perfect swimming holes and very difficult bolted walls. Unfortunately, graffiti has found its way onto the rocks and seriously detracts from what would be an amazing series of waterfalls and pools. Some sketchy ropes have been left for down climbing into lower pools - use them at your own risk (you can hike below the big pool by cutting uphill around the mini finger ridge on a small trail). If climbing is planned, be aware that the rock is very loose. New climbs will take serious cleaning to become solid. The area may be suitable for groups in time, but too few routes are developed as of now and the rock is too loose for official OTL trips. The area could be well served by an OTL trip to clean up the pools which would lead to a great local spot. Back on the dirt road, Mountain Biking in the area is excellent. The dirt road continues past the creek and the right fork can also be explored.
As mentioned, loose rock is a serious hazard to potential climbers and hikers. Poison Oak is very common along the trail and around the first two crags. Leave the canyon in the event of heavy rainfall to avoid flash flood danger.
