What you should know
Road conditions: The access road to Rio Viento RV Park requires careful navigation. "The road to get into the park is rough but take your time, it's worth the drive," advises one camper. Multiple reviews mention this challenge, suggesting drivers slow down considerably.
WiFi limitations: Internet connectivity varies significantly between parks. At Flag City RV Resort, "WiFi is listed as free, they put a disclaimer in if you want to stream videos, you must PAY for more," notes one reviewer who found this policy disappointing.
Tent camping options: Limited tent camping exists in the area. At SacWest RV Park & Campground, a reviewer noted their tent experience: "Camp site is clean. You can order food and they will deliver. Wonderful ada bathroom/showers with a fold down bench."
Tips for camping with families
Pool amenities: Several RV parks offer swimming pools for children. "Pool, game room, wifi, SHOWERS!" exclaimed one happy camper at SacWest RV Park, highlighting features that appeal to families with kids.
Wildlife viewing opportunities: Children often enjoy watching local wildlife. "Having Canandian snow geese in our site upon waking up was a real treat," mentioned a visitor to Sherwood Harbor Marina & RV Park, providing a memorable nature experience.
Avoid breed restrictions: Some parks maintain pet policies that restrict certain dog breeds, particularly for families traveling with pets. "I called to stay one night. I have a German shepherd service dog with medical paperwork to support that. They still said no and didn't care if my dog was a service dog or not," reported one frustrated traveler.
Tips from RVers
Site selection for shade: RVers recommend requesting shaded sites when available, especially during summer months. "We got lucky and parked under one of the only trees in the park which made it feel more welcoming," noted a camper at Cal Expo RV Park.
Extended stay discounts: Weekly and monthly rate options can significantly reduce costs. "We paid $58 for the night, a clean concrete patch, small trees with little or no shade but full hookups," mentioned one overnight visitor who felt prices were high for single-night stays.
Leveling challenges: Some parks feature uneven sites requiring leveling blocks. At Cal Expo RV Park, sites are "nose-down, not necessarily level, and your septic goes uphill to drain," according to one experienced RVer who still found the location convenient for exploring the area.
