We actually didn't get to stay here, but we've stayed here numerous times in the past. This is the second time we tried to stay here but they were "full". While this is an "RV Park", it's become like so many these days, a relatively inexpensive permanent home for people. There are now very few sites available for travelers, so if you want to stay here make sure you make a reservation far in advance. The low score is due to lack of available "visitor" sites, and the attitude of the manager/owner? The office person used to be very nice, but this is the second time we've encountered this office person and he has no business in the front office. We won't stay here again. With no help from the "manager", we found a space at the Yakima Washington Sportsman's State Park, very nice.
This park has seen better days, but it appears that the current operators are working at restoring it. There are new restrooms and a small laundry as evidence of this. The biggest attribute this park has is its proximity to the Bay Area. It's about 20 minutes to the Pittsburg/Bay Point BART station where you can be in downtown SF in less than an hour. The driveway entry is very steep, but also quite short. The worst thing about this park is the road leading to it. The road turnoff is about 3 miles from the park. The road is built on old dikes and the pavement condition is terrible and you can't really travel it faster than about 10 MPH.
We stayed 6 weeks at the monthly rate. The management, owner, and help were very helpful and friendly. This is the old Montrose KOA so there are also a few camping cabins available. Ideal location, off the highway/streets, minutes to the center of town, great medical services, and pretty much any other kinds of services and shopping you might want. Great pull-throughs for short stays. Only negative experience was a problem with sprinklers watering the RV and car with irrigation water (very bad water spotting), but the owner was working that problem. We'd do both long term and short term stays here again.
We stayed here on the Passport America rate on a Sunday in a 35' motorhome. Although many sites were available, the site (149) we finally chose as the least of all evils wasn't level (our hydraulic jacks couldn't level our coach), although the setting was beautiful with the lake, the park looked very trashy. Their "best site" offered to us turned out to be behind the store/bar, next to the road, and next to the boat ramp, not our kind of site at all. Most sites are very small and pushed together. We wouldn't stay here again.
This is a Passport park but the charge the full rate on Friday & Saturday. Access to the sites is poor, very narrow over drainage pipes, and the soil is very sandy. The sites have a very narrow gravel pad and a picnic table. Access to the pads is over ungraveled soil and a heavy rig can get stuck (we did). No dumpster is provided for garbage, only a large garbage can which was overflowing for several days. Wi-Fi was good at times and not at others, and when the manager left one day it was totally unavailable. We would not stay here again.
$18 rate was Passport America. They limit the number of PA customers depending on availability. They warn you of watering schedules because the irrigation water leaves lots of spots on your rig. Great pool for the kids but not for swimming.
Sites are over 50' deep but not wide enough to put slideouts out without encroaching on adjacent sites. Recent management directive is that if you encroach on adjacent sites you will be charged for 2 sites. There are no facilities, only a site to park in. Rate is $20 for drive-in's. $16 rate requires prepayment at Fair office or by credit card.
Back of park (Bayview section) has a large population of transient workers (oil refinery) that make this more of a "Trailer Park" than an RV Park as a function of the early morning noise and general park appearance (lots of old trailers). Not an attractive place to stay but the proximity to the local bayfront and Thompson Trail (walking and biking) is nice.
