Camping opportunities around Usk, Washington concentrate in the Colville National Forest region with many sites situated between 2,100-2,400 feet elevation. Summer daytime temperatures typically range from 75-90°F, while evenings can drop to 45-55°F even during warmer months. Many campsites in this region remain accessible from late May through mid-October, with some primitive options available year-round depending on snow conditions.
What to do
Fishing at Thousand Trails Little Diamond: The lake is stocked regularly for fishing enthusiasts, creating opportunities for anglers of all experience levels. "The lake is perfect and a nice walk from the campsites. Fishing was so so," reports Dan P., who visited despite the campground being short-staffed during a busy Father's Day weekend.
Trail exploration beyond the lake loops: Several campgrounds connect to longer forest trails that extend beyond the water features. At Pend Oreille County Park, "There are miles of hiking/biking trails in this dense forest. The day use is free and has plenty of parking," notes Douglas S., highlighting the extensive trail system that's often uncrowded despite being accessible from Highway 2.
Bird watching and wildlife spotting: The forest and lake environments support diverse wildlife viewing opportunities throughout the seasons. One camper at Albeni Cove remarked, "Hearing the birds was really cool," while camping in the area, demonstrating the natural soundscape that enhances the outdoor experience.
What campers like
Privacy between sites: Campers consistently mention the spacing and natural divisions between camping areas. At Thousand Trails Little Diamond, Rich S. notes it's "One of the nicest KOA's we have stayed at. Peaceful at night, nice pines surrounding sites, friendly and attentive staff, and a ton of activities."
Clean facilities: Many dog friendly campgrounds near Usk maintain their facilities well despite remote locations. "Pit toilets were the cleanest I've ever seen. There is a nice trail that goes around the lake where you will see a variety of wildlife," reports Scott B. about his experience at South Skookum Lake.
Cooling shade during summer months: The dense tree cover provides relief during hot days. Douglas S. observed at Pend Oreille County Park that "The best thing about this place is how dense the trees overhead are, the whole area is well shaded for those hot summer days."
What you should know
Limited cell service: Connectivity varies significantly between locations, with some offering surprising coverage. At Browns Lake Campground, be prepared for minimal service. However, at South Skookum Lake, Marcus K. notes, "The beauty of being so close to it there is cell service so if you need to get in contact with anyone, it's about a two minute walk."
Road conditions to remote sites: Access roads to some of the most secluded pet-friendly camping spots require careful navigation. Jennifer R. describes reaching Cooks Lake: "The road to get there was approx six miles of gravel winding single lane road. But so worth the drive for the beautiful shaded sites and the open Lakeview sites."
Seasonal availability: Operating seasons vary by campground, with many closing after Labor Day. Douglas S. mentions that Pend Oreille County Park runs "May to September," while Buck L. notes at Thousand Trails Little Diamond: "Very few of the KOA campsites have sewer hook ups. There are dump sites available. There is also a mobile pumpout service available if you want to pay for it."
Tips for camping with families
Playground proximity: For families with children, certain sites offer better access to play equipment. Dan P. advises about Newport Little Diamond Lake KOA: "If you are camping with kids the spots closer to the playground equipment are perfect."
Lake temperature considerations: Most lakes in the area become comfortable for swimming by mid-summer. "The lake was great for a swim and to play fetch with our dog," reports Taylor T., who found the water conditions ideal during their visit to South Skookum Lake.
Weekend popularity: Family-focused campgrounds fill quickly on weekends and holidays. Garry S. warns about Thousand Trails Little Diamond: "Thousand Trails Member, this is a first come, first served, so get here early, they fill up fast!"
Tips from RVers
Site positioning challenges: At many campgrounds, hookup placement requires careful parking. As Gary K. explains about Little Diamond Lake: "The sites share electric and water, no sewer and are positioned oddly they are on the off side and in front by the road. Some 30 and 50 amp just check the box. The sites are gravel, somewhat level and size/length varies, a few pull throughs, our 37ft 5ver had no problem."
Dump station availability: While hookups are limited, most established campgrounds offer dump facilities. Buck L. explains, "There are dump sites available. There is also a mobile pumpout service available if you want to pay for it. Shower and toilet facilities were very nice and always clean."
Limited big rig access: Many pet-friendly camping options near Usk have size restrictions. Jennifer R. notes about Cooks Lake: "At least 2 of them are good for my trailer although I wouldn't try if you're not experienced with towing. The road to get there was approx six miles of gravel winding single lane road."
