Need to Know
The trail up Icehouse Canyon follows the stream at a steady climb past several private cabins. If you are running early, respect the residents and keep your voices down. Also keep a look out for deer and Nelson's Sheep farther up the canyon. At about 2.4 miles, listen for Columbine Spring, which is just below the trail. This spring typically has water year round. From here, the trail continues its climb for approximately 1.0 mile to Icehouse Saddle. Along the way, you'll cross the intersection of the Chapman Trail #7W07, which you'll use on your return trek. Take a break at Icehouse Saddle and grab a snack, but be aware that this saddle is often windy.
Icehouse saddle is a junction of several trails which can take you to the Three T's Trail #7W06, Middle Fork Trail #6W01, Ontario Peak Trail #7W08, Kelly's Camp and Bighorn Peak Trail #7W08A. You want to take the Cucamonga Peak Trail #7W04 to the southeast. This trail offers views of the I-15 far below and the Lytle Creek watershed as it slowly traverses the contour lines at the base of Bighorn Peak to the west.
The run to the Cucamonga Peak Spur trail is approximately 2.1 miles from the Icehouse Canyon Saddle. It has a few steep, challenging scree and rock areas, but nothing too difficult. Once you reach the spur trail to the peak, stay right and climb to the top. This spur trail is heavily used and easy to follow. Take a break at the top as you are rewarded with great views of the Inland Empire. Make sure you look north for great views of Mt. Baldy!
After enjoying Cucamonga Peak you'll take a use trail off the peak to the northeast. It is hard to get lost here. If you go too far to the right (east/south), the steep drop from the ridge will turn you back. If you go too far left (north) you'll run back into the main Cucamonga Peak Trail #7W04. Follow the trail just off the ridgeline until you intersect with the Cucamonga Peak Trail #7W04.
After intersecting the main trail, continue east. You are now only 1.0 mile from Etiwanda Peak! Near GPS 34.2289, -117.5737 there is an obvious spur trail to the right that will take you to Etiwanda Peak. The spur trail is steep, but it is also short! Once on top enjoy the scenery. Not many people bother running up to Etiwanda Peak, but the views are not to be missed! (Dare I say perhaps better views than Cucamonga Peak?)
Once you have enjoyed the view and solitude (no people) at Etiwanda Peak, return via the spur trail and begin running west on the Cucamonga Peak Trail #7W04 back to Icehouse Saddle. Along the way you'll pass the Cucamonga Peak Spur trail. From Icehouse Saddle take the Icehouse Canyon Trail #7W07A until the intersection with the Chapman Trail #7W07. Follow the Chapman Trail #7W07 through Cedar Glenn campground until it intersects back with the Icehouse Canyon Trail #7W07A. You are now about 1.0 mile from the parking lot!
