Just west of Riverside/San Bernardino is Ontario, a city anchored by the area’s regional airport, Route 66, and Cucamonga-Guasti Regional Park. The best places to run in Ontario are several multi-use trails, some small parks, and trail running in the San Gabriel Mountains
Pacific Electric Trail. This ‘Rails to Trails’ path trail runs for 20 miles between Claremont and Rialto. A good spot to catch the trail in central Ontario is the parking lot at the Route 66 Trailhead off Foothills Blvd. Some nice views of the San Gabriel Mountains. Part dirt, part gravel. Note: open and exposed. There are some drinking fountains along the way. ROUTE MAP
Cucamonga Creek Trail. This is a centrally located multi-use path in Ontario. It’s a good bet for those staying in the Airport/Convention Center area. The paved trail goes from E 4th St. at Cucamonga-Guasti Regional Park (just north of the Airport) north for 6.2 miles to E 24th St., just below the mountains. Good add-ons are trails in Cucamonga Regional Park & Red Hill Park (where it intersects w/the Pacific Electric Trail. ROUTE MAP
- Add-Ons: Upland Trails. ~1.5 mile loop on trails off E 19th St., just below Foothills Fwy; Red Hill Park, ~1.3 miles out and back.
