Dos Reis County Park

6 ReviewsAdd Review

Fishing enthusiasts will find direct access to the San Joaquin River at Dos Reis County Park, a county-managed campground located half a mile off Interstate 5 in Lathrop. The facility sits behind a protective dike that helps reduce highway noise while maintaining easy access for travelers. This small loop contains over 20 sites, all equipped with full hookups accommodating RVs up to 60 feet.

The campground operates year-round with spacious back-in sites featuring covered picnic tables and fire pits. Several reviewers mention the sites provide adequate privacy, though site 14 is noted as a pull-through with closer proximity to neighboring campers. Donald T. notes "Trails to hike and bike" are available on the property. Shower facilities operate on limited schedules with designated morning and evening hours.

Campers report mixed experiences with maintenance and camp host responsiveness, with some noting inconsistent upkeep of common areas and restroom facilities. The presence of feral cats around the campground requires securing outdoor items. A few sites appear to house long-term residents alongside overnight campers.

For those wanting additional amenities, French Camp RV Park and Golf Course provides a more resort-style experience just over four miles northeast.

A small county park campground offering spacious sites with full hookups and basic amenities like fire pits. Some visitors reported noise issues from other campers and tight site spacing, though others found it peaceful.

So much lost potential

The campground is in a good location, nice view, spacious sites at a fair price. Unfortunately, this campground could be an easy 5 stars if the camp hosts were more invested but I'm sure they are living there for free and not having to do much at all except drive around on their golf cart every couple of days. If they were invested in their responsibilities as a camphost, they wouldn't take up three spots for their extra vehicles because they'd be full. They also don't walk the park or the grassy areas(trash throughout), no clean up of sites or fire pits(dog waste bags and plastic trash bags in fire pit and broken glass at site), and they don't unlock the showers at the posted times(you get 2 hrs in the morning and 2 hrs in the evening to use showers if they're not locked up), nor do they clean the bathroom which was pretty gross the whole week I was there. The sign says to let the camp host know if the showers are locked during scheduled use times but good luck getting past their GS who lets you know not to bother them. On top of those issues, the feral cats will urinate/spray on anything left outside your rig. This park could easily get full and stay that way if issues were addressed but it's obvious that someone knows someone. If you get my drift. It's disappointing and I won't be back.

Great Option for an Overnight Stop

A half-mile off of I-5, far enough to dampen the interstate roar, and separated by a dike from the San Joaquin River.  Not a lot to do in the surrounding area, no obvious hiking trails, for example, although some fishing seems to have been possible. A small loop of 20+ sites, all (it appeared) with full-hookups.  We had a back-in site with no trouble for a 17' trailer. Small oddities (a site or two with what looked like permanent residents, showers with limited hours in the morning and evening, unclear signage on how and where to register), but a classic municipal/county park campground, that was a quiet and welcome alternative to commercial camps.

Ok for basic medium size RVs

This campground will not work for people wanting a one night stay because there are no pull through sites and each campsite would require disconnecting the trailer or tow car to fit in the site.

Camp site as a waypoint to the destination.

A couple of campers didn't respect the quiet time rules and it ruined my whole experience at the site. It wasn't our final destination so my basic expectation was fulfilled. 

#14 is a pull-through lot and we were very close to surrounding sites, so we felt we didn't have enough privacy.
