Fishing draws the most consistent crowds to Mardon Resort, and for good reason. The resort sits directly on Potholes Reservoir, a large body of water about 16 miles southwest of Moses Lake, with a boat launch just steps from many sites. Full hookups accommodate RVs up to 50 feet, and the property includes a marina, a restaurant and bar, a fully stocked store, and golf cart rentals for getting around the grounds. Central Washington runs dry and hot through summer, so the reservoir access matters more than it might elsewhere.
Crowd levels are one of the most frequently mentioned details in reviews. Weekends fill up fast, and the resort has operated in this capacity since the 1970s, which gives it a well-worn, established feel rather than a remote getaway. That said, sites tucked among willow trees along the water provide more separation from neighbors than the open RV sections. Campers have a choice between sandy beach-level spots and higher ground with views over the reservoir.
Anna W. sums up the layout well: "Camp on the water on the beach or up higher." Amenities include drinking water, showers, sewer hookups, a dump station, and WiFi, making this a practical base for anglers who want full services without sacrificing water access. Nearby options like Corral Lake and O'Sullivan Sportsman Resort give anglers additional staging points along the reservoir corridor. Reservations are available and pets are welcome.
