Best time to visit Potholes State Park

Late spring through early fall is the most comfortable window for RV travel, with May, June, and September typically offering warm days, cooler nights, and fewer crowds than midsummer. July and August bring the hottest temperatures and the busiest weekends, especially for boating and fishing, so reservations are recommended. Shoulder seasons in April and October are good for birdwatching and quieter camping, though nighttime temperatures can drop near freezing. Winter visits are possible but cold, with limited services and occasional snow or ice on park roads.

Things to do at Potholes State Park

  • Fishing on Potholes Reservoir Easy
    RV parking available

    Potholes Reservoir is widely regarded as one of eastern Washington's top fisheries, with walleye, largemouth and smallmouth bass, rainbow trout, crappie, and perch. The park's boat launch provides direct RV-accessible access to the lake, and anglers fish from boats, the shoreline, and the dunes area. A Washington fishing license is required.

  • Boating and Paddling
    RV parking available

    The reservoir offers miles of open water and a maze of dune islands and sloughs popular with motorboats, kayaks, and paddleboards. The park boat ramp is suited to trailered boats, and the launch parking area accommodates vehicles with trailers. Wind can pick up quickly in the afternoon, so plan early launches.

  • Swimming and Day Use Easy

    Designated swimming areas along the park's shoreline draw families in summer. Sandy beaches, shaded picnic tables, and nearby restrooms make it an easy half-day stop for RV campers. Water levels fluctuate with irrigation releases, so check conditions on arrival.

  • Wildlife Viewing at Potholes Wildlife Area Easy
    RV parking available

    The adjacent Washington Department of Fish and Wildlife Potholes Wildlife Area and Columbia National Wildlife Refuge attract large numbers of waterfowl, raptors, and migratory birds. Spring and fall migrations offer the best viewing, with pullouts and trailheads along nearby roads. RV parking is available at several refuge access points.

  • Drumheller Channels Exploration Easy

    The Drumheller Channels National Natural Landmark just south of the park showcases dramatic scablands carved by Ice Age floods. Visitors can drive scenic backroads, pull off at viewpoints, and spot unique basalt buttes and coulees. Most viewpoints have room for RV parking along wide shoulders. nps.gov/iafl/planyourvisit/washington-state.htm

  • Sand Dunes Exploration Moderate

    The dune area along the reservoir's north shore offers a distinctive desert landscape within the park's reach. Visitors can walk the dunes, fish hidden sloughs, or photograph the stark scenery. Access points are accessible by vehicle with ample parking.

  • Picnicking and Shoreline Walking Easy
    RV parking available

    The park's day-use area offers shaded picnic tables, open lawns, and easy shoreline paths for relaxed strolls. It is a low-effort option for rest days between longer drives. Large pull-through and paved spaces near the day-use area accommodate motorhomes and towables.

Great

Christy M. - Aug 2024

Mari communicated well, and was very flexible. My truck didn’t have air shocks, so we decided not to tow. Mari towed the trailer to our destination and set it up as well as picked it back up. Very easy.

How to get to Potholes State Park

The park sits about 15 miles southwest of Moses Lake and roughly 120 miles west of Spokane via Interstate 90 and State Route 262, a drive of about two hours from Spokane International Airport, the closest major fly-and-rent hub. From the Seattle area, expect a drive of about 175 miles, or roughly three hours, over Snoqualmie Pass on I-90, which can require chains or traction tires in winter. The final approach follows paved two-lane highways with gentle grades and no tunnels, making it straightforward for most RV classes. Watch for strong crosswinds on the open basin highways and limited fuel options on the last stretch to the park.
