Tri-Cities area RV campgrounds maintain space for large motorhomes with pull-through access at most facilities. Summer temperatures frequently reach 95-100°F in Kennewick, making shade and air conditioning essential from July through September. Sites along the Columbia and Yakima Rivers offer water access, though swimming conditions vary by location.
What to do
Wine tasting tours: Several campgrounds in Prosser provide strategic access to over 30 local wineries. Wine Country RV Park serves as an ideal base for wine enthusiasts, with "a shuttle van" available for transportation between tasting rooms according to camper Russ H., who notes the park is "amazing" for those exploring local wineries.
River recreation: The Columbia River provides multiple water access points for boating and fishing. Umatilla Marina & RV Park offers "boat-in" access with "a nice park and swimming area for kids," according to reviewer Jill T. The location includes "a large parking lot and spots to clean fish" for anglers.
Golfing excursions: Horn Rapids RV Resort sits "across from a major golf course" as noted by Rachel A., making it convenient for golf enthusiasts. The park's "golf course quality" landscaping extends the golfing atmosphere into the camping experience.
What campers like
Private bathroom facilities: Horn Rapids RV Resort provides exceptional bathroom amenities, with Matthew S. noting that "hot water showers, toilets, water at your site and power for 50/30/20 amp cords" are all available. The facilities are consistently rated highly for cleanliness.
Swimming options: Several parks offer pools for relief from summer heat. Columbia Sun RV Resort includes a "heated pool and hot tub" that Jeff M. describes as part of the "all the amenities and activities you want in a semi-urban RC resort / glamping get away."
Level sites for easy setup: Beach RV Park provides well-maintained sites with minimal setup challenges. Bud S. found the park "quiet and shaded right by the water" with helpful staff who went "way above and beyond" when the office was closed.
What you should know
Long-term resident considerations: Many RV parks in the area have significant numbers of permanent or seasonal residents. At Coyote Run RV Park, Kristen S. observed "several long-term residents due to the skirting around so many of the RVs," though most maintain well-kept sites.
Highway noise impacts: Traffic noise affects several campgrounds near major roadways. At Umatilla Marina & RV Park, reviewer Judy T. noted "the truck traffic over the I-82 bridge was noisy" and Annie B. mentioned "you will see it and hear it" regarding the freeway.
Reservation requirements: Wine Country RV Park maintains strict reservation policies, especially during peak wine tourism seasons. Kristin S. rated the "Reservation Process/Ease of Getting a Site: 5" but noted seasonal capacity varies significantly.
Tips for camping with families
Water play opportunities: Umatilla Marina provides dedicated swimming areas suitable for children. Michelle M. states "It's nice down by the water you can swim or fish," making it appropriate for family water recreation during summer months.
Playground access: Columbia Sun RV Resort offers "a small playground and basketball hoop for kids" according to Kristin S., providing entertainment options when not exploring the region. The facilities complement the pool area for comprehensive family activities.
Pet restrictions: Weight limitations for pets exist at some Kennewick area RV parks. Wine Country RV Park has a "40 POUND LIMIT" for dogs according to Michael C., who noted these restrictions apply even for traveling families with larger pets.
Tips from RVers
Adapter requirements: Electrical hookup compatibility varies between parks. At Beach RV Park, one guest appreciated that staff "loaned a 30 to 50 amp adapter so we could hook up our 30 amp plug" when needed, preventing potential power access issues.
Pull-through navigation: Coyote Run RV Park receives high marks for accessibility, with Jerold H. describing "pull through sites that were easy to navigate" and noting the campground has "one loop with back in sites on the perimeter and pull-through sites on the 'infield'."
Site privacy considerations: While most rv campgrounds near Kennewick, Washington feature standard spacing, some offer better separation. At Umatilla Marina & RV Park, Ray V. noted his "28' class C with a toad" fit comfortably as "the pull their site was able to accommodate both vehicles with a problem."
