This is one of only 2 big RV parks in the San Gabriel Valley of Los Angeles County. I would choose the other one over this KOA for any stay longer than a weekend. Although the sites are all paved and pull-through, they are too close together. We had barely enough of a grass strip to put out slides, let alone set up a chair. The laundry room is in desperate need of an overhaul; many dryer doors actually have cracks in them. The pool is kept clean; the showers are not.
We enjoy this RV park and have stayed as monthly residents in the past. It is best not to stay in section "F" down near the lakefront on weekends or holidays. The parties can get noisy and out of control. There are skunks everywhere so keep pets leashed. Choose sections B or C for the best view of the lake.
Beware! The sites in this park are very small; small enough to be a fire hazard. We have 18 inches between our slide and the rig next to us. The advertisement of a hot tub is incorrect - it is the owners' personal jacuzzi on their patio. Very disappointing. We will not stay here again.
