The Moses Lake region around Othello sits in Washington's Columbia Basin at approximately 1,050 feet elevation. This semi-arid area receives just 7-9 inches of annual rainfall, creating a desert landscape with dramatic temperature variations between seasons. Winter camping temperatures often drop below freezing while summer brings 90°F+ days with minimal shade at many lakeside sites.
What to do
Fishing for walleye and bass: O'Sullivan Reservoir near Potholes State Park Campground offers excellent angling options. "Great fishing if you have a boat, but with no easily accessible shore, it's not great for shore fishing," notes Stephanie S., who recommends bringing a boat for better access.
Wildlife viewing: The wetlands surrounding Long Lake support diverse bird populations. "I was one of only 3 campers in and around long lake. Lots of privacy," reports Luther R. Campers frequently spot "pelicans and weasels" according to Trenton G., particularly during morning hours.
Off-road recreation: Moses Lake Mud Flats and Sand Dunes provide terrain for ATV enthusiasts. "If you want a place to bring all of your motor toys for a fun long weekend in October? Get over to Moses Lake, WA where you will find Mud Flats and Sand Dunes!" writes Dani H., who recommends visiting during off-season for smaller crowds.
What campers like
Spacious sites: Sage Hills Golf Club & RV Resort features oversized camping areas. "Never been to an RV Park where all the sights r 50' plus and pull-thrus," mentions Tom A. The sites include "Lots of grass b/n sights" making them particularly comfortable for longer stays.
Water access: Mardon Resort offers direct lake frontage with beach camping. "I love camping in the sand, we always stayed among the willow trees. Wake up hot and jump in the reservoir," says Anna W., highlighting the convenience of lakeside sites during hot summer months.
Quiet atmosphere: Warden Lake RV Resort provides a peaceful environment with controlled access. "The gated entry provided extra sense of security and it was a very relaxing stay," notes Steve B., who appreciated the resort's tranquil setting near Moses Lake.
What you should know
Road conditions: Access to some dispersed sites requires preparation. "The road is washboarded out. Your teeth will rattle out of your head. It is passable by car, though," warns Beamus R. about Long Lake, recommending higher clearance vehicles during early season visits.
Weather preparation: Central Washington experiences extreme temperature fluctuations. "The climate is arid desert so expect hot days, cool nights, and occasional gusty winds," explains a visitor to Potholes State Park, suggesting packing layers for comfort.
Wildlife awareness: Desert wildlife includes snakes. "We did see two snakes. One swimming towards us while we were fishing on the boat, the other in our camp site. This was a baby rattlesnake," reports a camper at Potholes State Park, recommending vigilance especially with children or pets.
Tips for camping with families
Playground access: Coyote Run RV Park provides family-friendly amenities despite its highway-adjacent location. "This is a nice, clean park. Has tent sites, back ins, pull thrus, and has bathrooms and a laundry room onsite," mentions Schuy K., noting the park serves as a good overnight stop.
Swimming options: Moses Lake offers swimming beaches during summer months. "I love this place because it's so spacious and they have a playground for children to play," writes Nikki R., though cautioning that "the lake was a bit muddy and had lots of grown seaweed."
Pet management: Most dog friendly campgrounds near Othello enforce standard leash rules. "The sites are big and well spaced along the reservoir shoreline," notes a visitor to the area, making it easier to maintain space between pets and other campers.
Tips from RVers
Full hookup availability: O'Sullivan Sportsman Resort provides complete RV services in a manicured setting. "This has to be the largest, fanciest site we've ever stopped at to date. It's right next to a golf course, it's absolutely gigantic and incredibly well manicured," shares Rachel A., noting the amenities justify the higher price point.
Seasonal considerations: The Legacy Resort at Frenchman Hills offers shade crucial during hot months. "Very quite and well shaded," reports Michael, making it preferable to more exposed sites during peak summer heat when temperatures regularly exceed 90°F.
Overnight logistics: For travelers passing through, Coyote Run provides convenient highway access. "Not much around here but if you are driving by this place is clean and reasonable. They have a very wide road through the park which is nice and long pull-through sites," explains Dave S., highlighting its usefulness for single-night stays.
