The Sacramento-San Joaquin River Delta region surrounding Discovery Bay sits at near sea level with a Mediterranean climate marked by hot, dry summers and mild, wet winters. Average summer temperatures reach the mid-90s °F with winter lows rarely dropping below 40 °F. Waterfront RV parks near Discovery Bay offer direct access to over 1,000 miles of Delta waterways, with sites often filling quickly during peak boating season from May through September.
What to do
Fishing excursions: The Delta waterways near SacWest RV Park & Campground provide excellent opportunities for catching striped bass, sturgeon, and catfish year-round. "The camp site is clean. You can order food and they will deliver. Wonderful ada bathroom/showers with a fold down bench. Friendly staff. Near freeway (lots of traffic noise). Quiet morning," notes a camper who stayed for a quick visit.
Wine tasting: Several wineries near Flag City RV Resort offer tastings within a 15-minute drive. "Clean and level facility. Restroom and showers are well kept. Store and check in area very nice. Not a big fan of the lava rock site area, would prefer grass. Otherwise a nice stay with wineries, breweries, golf and other outdoor activities near by," shares a reviewer.
Kayaking: Rent kayaks at the marina adjacent to many Delta RV parks for self-guided exploration of waterways. "Wonderful rv spot, the staff are welcoming and very helpful. The grounds are kept up, every site has a fire ring with picnic tables. The bathrooms are decent and dump Station is clean. This is definitely a favorite spot of ours," notes a visitor to Turtle Beach.
What campers like
Spacious sites: The Delta region offers several RV parks with generously sized camping spots. At Rio Viento RV Park, a camper notes, "Very nice large sites with large grass areas pet friendly, amazing helpful and friendly staff. My only complaint is no Wi-Fi. Other than that I would recommend this park. The road in is very bumpy, so take your time."
Waterfront access: Many campers appreciate direct water access from their sites. "We stayed on large grass site next to the water. Very nice. Few amenities and staff was scarce but more than adequate. Lots of room to roam for people & pets," reports a visitor to Thousand Trails Turtle Beach.
Dog-friendly amenities: Several Delta RV parks feature dedicated pet areas. At SacWest, one reviewer appreciated "a wonderful dog park" while another mentions "Expensive and can be noisy if on the west side near the truck stop." Flag City RV Resort offers "a HUGE fenced area to walk your dog OFF LEASH" according to a satisfied camper.
What you should know
Road conditions: Access roads to several Delta RV parks require slow, cautious driving. A Rio Viento visitor warns, "The only issue I had which has nothing to do with the park is the road leading into the park is extremely [rough]." Another camper agrees: "The road to get into the park is rough but take your time, it's worth the drive."
Seasonal crowding: Summer weekends bring heavy traffic to Discovery Bay area RV parks. "Nice place, great staff. Gets really busy weekends and holidays," notes a visitor to Sugar Barge RV Resort & Marina.
Site variability: Some RV parks have mixed site quality even within the same facility. "We have a nice site right now, but decided to park the truck at a nearby on-site lot due to the size of this space (but we were thankful they worked us in, and our truck did fit, but so close to a family with 3 or 4 kids so they needed a little breathing room!)" explains a Sugar Barge camper.
Tips for camping with families
Swimming options: Many Delta RV parks feature pools during summer months. At SacWest, a family enjoyed "Pool, game room, wifi, SHOWERS!" while another mentioned "lots of things to do for kids: great playgrounds, swimming pool, more than 100 ducks going around!"
Entertainment planning: Bring water toys and games as many parks have limited organized activities. "It was clean, had friendly staff, and a wonderful dog park. We will be back," notes a family at SacWest who extended their planned one-night stay.
Site selection for kids: Request sites away from water if traveling with small children. At Windmill Cove RV Park, a family notes: "The beach to play and swim it a about a 10min walk from your camper. But you will more than likely come across some great people that will have you hop on their golf carts and give you a lift."
Tips from RVers
Hookup challenges: Be prepared with extra hose length at some parks. A Sugar Barge RV camper warns: "My only complaint, the water spigot is really close to the ground and really close to the sewer drain. Scrub with bleach before booking up your water and you'll be fine."
Cell service limitations: Coverage varies significantly between rv parks Discovery Bay, California area. "Wifi and cell reception is really poor, even when you're right outside the office. Check for updates with them if they get a new cell tower nearby," advises a Sugar Barge visitor.
Winter stays: Off-season camping offers quieter experiences with milder temperatures. "We stayed here in January 2024 and got a Passport America discount. Traveling south on US-101, then US-12 east, our RV GPS took us right to this campground. Check-in was quick and easy, and we proceeded unescorted to pull through site 32 with FHUs," reports a winter visitor to Flag City RV Resort.
