The San Dimas Canyon Park Trail is a charming and accessible escape into nature, perfect for a quick refresh. This easy 1.2-mile (2.0 km) loop takes you through diverse terrain, from chaparral-covered hillsides to peaceful oak woodlands and even a new pine grove.

Planning your visit is simple, with convenient access points like the San Dimas Avenue parking lot or the flatter Valley Center Staging Area. While the trail is generally easy, covering 191 feet (58 metres) of elevation gain in about 34 minutes, it's wise to wear appropriate footwear, especially after heavy rains when stream crossings can be deeper. This trail is a fantastic option for families and beginners looking for a rewarding outdoor experience without a strenuous commitment.
Beyond the trail itself, San Dimas Canyon Park is notable for hosting the first nature center in the Los Angeles County Park system, offering a self-guided plant identification trail.

The Alosta Canyon and South Hills Backbone Loop offers a delightful mix of shaded canyon paths and open ridge views, making it a popular choice for a quick nature fix in Glendora. You'll traverse varied terrain, from dirt paths under the canopy of live oaks and sycamores to a wide dirt road along the backbone, where panoramic 360-degree vistas of the city unfold. Keep an eye out for glistening hilltops adorned with cacti and, in spring, a scattering of wildflowers.
This easy 2.1-mile (3.3 km) hike, with a manageable 245 feet (75 metres) of elevation gain, typically takes around 56 minutes to complete. It's a multi-use trail, so you might share the path with bicyclists and equestrians. For the best experience, visit during the cooler months of winter or early spring when the hills are vibrant green and the air is clear, or tackle it at daybreak during summer to beat the heat.
Nestled within the South Hills Wilderness Park, this loop is a true "island" of nature within the urban sprawl, easily accessible directly from the street. It's a fantastic option for a beginner hike or a family outing, offering a chance to reach "Summit 1212" for decent views, marked by a cairn and survey benchmarks. The trail system provides a great network of paths for exercise and a refreshing dose of the outdoors.
