The Best Camping Near Los Banos, California

We pulled up here on a Saturday night in May after striking out all along the coast, with the campgrounds there either being completely booked or crazy expensive.  This place was such a refreshing change, at only $20/night and plenty of wide open spots available. There were some other campers here but the vibe was so quiet and peaceful and nice. 

The sites each have a little shade structure, a fire pit, a grill, a trash can, and a picnic table. There are porta potties throughout and a handicap accessible pit toilet near the entrance. There are dumpsters but no recycling bins (weird for a California state facility).

Some of the sites have a water view and some have vegetation growing that blocks the reservoir. Sites are scattered all over with no division between them, and some are grouped together and would be good for a group camping together.  I'd drive around for a bit before making my choice of sites. The registration process was very easy: you just pay at the ranger station and drive in and pick your site, all very casual. 

Watch for mosquitoes at night, and watch for ticks! 

Great campground if you just need to stop for the night. It's right off 152, easily accessible, but far enough away so the road noise is muffled and distant. 

Good service with Verizon and Att. 

Bare bones and great

We were able to pull right into a stop right up on the reservoir. Super spacious for any type of trailer or motorhome. There were bathrooms and giant trash bins. Each spot had its own fire pit, grill and table under a shelter. 

Wide open spacious place

Good quiet stop for a one night stay and cheap but not much to do. However camping is super limited off interstate 5 this is probably the best camping directly in this area. Staff is super nice. The town 5 minutes away has an in and out, panda,and various taco trucks. There is also a gas station where you can take a shower. Really good pitstop camp to refuel and get supplies if need be.

Good one night stop off intertate 5

This is a nice place to stay a couple of nights. It’s close to the road yet quiet. The only problem are the mosquitoes and other insects. Carry repellent all the time. 

Nice place for a couple of nights

Loud music playing at this hour clearly says quite time is at 10 pm and it’s so loud

Loud people

This place always comes through for us when we need a quiet place to stay when traveling in the area. It's $20/night, there seems to always be room, and it's always been nice and quiet when we stay here. 

Sites are hit or miss, so drive around until you find one that suits you. One of these days we'll nab one of the sites to the right of the fork when you enter the campground, but they always seem to be taken.

Good cell reception, pit toilets, trash dumpster (no recycling).
