Hiking
The Bonelli Park Loop Trail offers a refreshing escape, circling the scenic Puddingstone Reservoir with continuous water views. You'll experience a mix of single track, fire roads, and paved sections, winding through rolling hills that burst with wild mustard in season. Keep an eye out for desert cottontails and various waterfowl, especially during quieter times of day. It's a moderate 6.7-mile (10.8 km) hike with a gentle 271 feet (82 metres) of elevation gain, typically taking around 2 hours and 48 minutes, making it a great option for a relaxed outing.
For easy access, you can begin your journey from multiple points around the park; Brackett Field often provides free parking, while the South Shore Swim Beach offers additional facilities. The trail is dog-friendly, just remember to keep your furry friend on a leash. Consider an early start to avoid crowds, particularly on weekends, and to enjoy the cooler temperatures.
This trail stands out for its accessibility within a metropolitan area, providing a genuine sense of nature without a long drive. It's a popular choice for families and beginners, but also offers more challenging sections in the foothills for those seeking a bit more exertion. The constant views of Puddingstone Reservoir and the distant San Gabriel Mountains make it a visually rewarding experience.
