River Island State Park offers camping, beach access and boat launches

River Island State Park packs 37 campsites, a protected cove beach and a boat launch into one compact stop in Parker. River Island Market sits a quarter-mile away, so tent campers, RV travelers, anglers, boaters and local families can stock up without forcing every errand back into town. Its use changes with the season: summer brings boating, swimming and jet skiing, while cooler months favor fishing and camping.

Camping built for different rigs

Eight beachfront campsites have 20-amp service and water, while the other 29 sites have 50/30/20-amp service and water. Ten sites are back-in spaces and 19 are pull-throughs, a split that matters to RV drivers who want a simpler arrival and to campers who need reliable hookups close to the river.

Two restroom and shower buildings, dump-station access and a 20-by-20-foot group ramada round out the basics that make a longer stay realistic. The ramada can host 12 to 65 people, which gives families and small groups a shaded meeting point when the sun is high. The park entrance sits in Parker at about 420 feet elevation, with GPS coordinates of 34.253457, -114.138594, just off the Colorado River corridor north of State Highway 95.

Boat access without the guesswork

River Island’s boat ramp is one of the park’s most useful pieces of infrastructure. The three-lane launch ramp sits in a calm cove, which makes loading and unloading easier than at a rough shoreline launch. That same cove is a no-wake zone, so it works best for people who want a controlled launch area rather than open-water speed.

An island reef sits in the center of the cove, and boaters need to hug the cliffs to reach the main channel. The beach itself spans the riverfront and is tucked inside the cove, protected from the river’s current, which is why it works for swimming, pausing on shore and beaching a boat for a break.

Trails, wildlife and family use

Its trail system connects with Buckskin Mountain State Park, and one of the better-known climbs goes up Wedge Hill for views over Colorado River country. That connection gives the park a wider role in the Parker area, since visitors can use it as a starting point for short hikes rather than treating it only as a campground or launch site.

Desert bighorn sheep, desert mule deer, coyotes, bobcats, birds, reptiles and other small mammals can all show up in the park’s landscape. Families with children have another draw in the Junior Ranger program, which gives younger visitors a reason to stay engaged beyond the beach and the campsite.

The OHV staging area adds another layer

A new off-highway vehicle staging area between Buckskin Mountain and River Island state parks adds another use in the region. In June 2025, Arizona State Parks and Trails marked Phase 1 complete and scheduled a ribbon-cutting for June 12, 2025, at 10 a.m. The staging area gives riders a secure place to stage tow vehicles, run pre-ride safety checks and gear up before heading onto desert trails south of State Route 95.

That access ties River Island into OHV Region 4, including the Arizona Peace Trail and the Nellie E. Saloon, also known as the Desert Bar. Improvements are still in progress, so weekday construction noise can be part of the visit.

Why Parker businesses feel the effect

River Island Market sits about a quarter-mile outside the park and offers groceries, deli food, gas, a clothing boutique and storage. Visitors still need ice, fuel, sandwiches, dry clothes and last-minute supplies, and the closest practical stop is right near the entrance.

River Island and Buckskin Mountain State Park sit within a couple of miles of each other, both on the river, both tied to State Highway 95 and both close enough to town to send visitors back for errands. Arizona State Parks and Trails has cited a study showing its system supported $555 million in statewide economic activity.
