RV parks near Prosser, Washington serve as convenient basements for exploring the Yakima Valley wine region, located at the eastern edge of the Columbia Basin. Average summer temperatures reach 90°F with less than 8 inches of annual rainfall, creating a desert climate ideal for vineyards. Most campgrounds in this area remain open year-round, though winter campers should confirm water hookup availability as temperatures can drop below freezing from November through February.

What campers like
Clean facilities: Many RV parks prioritize cleanliness, with bathroom facilities regularly maintained. At Columbia Sun RV Resort, campers appreciate the "beautiful golf course quality" grounds.

It's accessible about 1/2 mile from the park," notes a Wine Country RV Park visitor.
What you should know
Seasonal considerations: Summer temperatures frequently exceed 90°F, while winters can drop below freezing. "Winter travelers should confirm water hookup availability, as some parks winterize certain systems during colder months," advises a local camper.
Weight restrictions for pets: Some parks limit the size of dogs allowed. At Wine Country RV Park, one camper warns about "40 POUND LIMIT. We travel with our fur kids (over 40 pounds). Shallow minded management."
Reservation requirements: Umatilla Marina & RV Park across the Oregon border, approximately 40 miles from Prosser, requires advance booking during peak season. "Picked campground for an overnight stay. Right on the River! Little bit of freeway noise, but otherwise very quiet and peaceful. Level gravel sites with grassy area between sites," notes Roger M.

Tips from RVers
Site selection: Choose premium sites with concrete pads for easier leveling. At Wine Country RV Park, "Premium sites have concrete pads while the lower cost sites are just gravel. The pads are mostly level, but slope upwards in some spots so unhitching can be just a little tricky," explains one RVer.
Bridge noise considerations: Parks near the Columbia River bridges may experience traffic noise. "It is noisy with the bridge and Hwy right there beside the park," notes cindy about Umatilla Marina & RV Park, while adding that "Bathrooms and showers were excellent."
Pull-through availability: Many parks offer pull-through sites for larger rigs with towed vehicles. "Driftwood RV Park is small and very green Campground with just what you need as you're passing through. The caretakers of the property are available for questions and take great care of the place. Tables at each spot make it easy to cook and bathrooms are clean," says Alicia F.
