At the east end of Los Angeles County, at the junction of Pomona, San Dimas and La Verne, lies Puddingstone Reservoir, a flood control and groundwater recharge facility that for decades has been a draw for its fishing, boating and swimming. It is surrounded by Frank Bonelli Regional Park and the huge Raging Waters water park, while the LA Fairgrounds (Fairplex), and Bracket Field small plane airport are adjacent.
East Shore RV Park (some tent sites too) has some 500 sites, although 300 of those are long term. Built in the hills above the lake, many sites have panoramic views of the lake and the San Gabriel Mountains.
At the lower, or “Unit F” Loop, two trailheads lead to our main attraction, a fairly easy bike route around the reservoir, with only a handful of manageable hills. It is a combination of paved lakefront promenades along the north and south sections of Bonelli Park, a scenic novice mountain bike trail, and a long easy scenic cruise across Puddingstone Dam. It is a 5-mile loop, or 8-9 miles if you opt to cycle on Class I/III roadways around the airport, perhaps stopping at Norms Hanger cafe for breakfast or lunch, a popular thing to do with cycling groups.
Bonelli Park has a lot of trails throughout, and much of it is more challenging mountain bike singletrack. For those who like to stick to roadways, there are both easy and difficult hilly options around the lake. East Shore RV Park is expensive, and is full well in advance most weekends. We take advantage of the 3-for-2 weekday special.
