Veteran hikers might not get too excited about a paved path that parallels a concrete channel, but the popular Thompson Creek Trail is worth a visit if you’re in the area. Inland Empire and San Gabriel hikers might want to keep it in mind during the hot summer months; area residents who want to get out into nature but are a little intimidated by the tall San Gabriels might well also find the Thompson Creek Trail a worthwhile destination. The trail is popular with bikers, joggers and dog walkers, so expect a lot of company.

From the parking area at the end of Towne Avenue, turn right at the gate and begin your walk. The trail passes Mountain Avenue at 0.5 miles, and soon afterward comes to Higginbotham Park, where there are restrooms. Across the channel from the park, the Sycamore Canyon area is currently being refurbished, and will hopefully soon become accessible.

At just over a mile, the trail bends slightly and starts heading northwest. Your view is livened up by bright red toyon berry bushes, and you’ll get glimpses of the Ontario/Cucamonga Ridge between the tall eucalyptus trees lining the path. At 1.6 miles, you cross Pomello Drive and enter a flood plain, with the mountains prominently off to the left and straight ahead.

The trail ends at Mills Avenue (2.1 miles). If you have time, you can head north on Mills and explore the Claremont Hills Wilderness Area.
