Onalaska camping areas sit at an elevation between 500-800 feet above sea level in the Cascade foothills. The region experiences mild summer temperatures averaging 75-85°F during peak camping season with evening lows in the 50s. Most campgrounds remain open year-round, though winter camping requires preparation for temperatures that can drop below freezing with occasional snow between November and March.
What to do
Kayaking at lakefront spots: Waterfront sites at Mayfield Lake Park give direct boat access right from your campsite. "We were able to reserve a lakefront spot. We were able to beach our boat right in front of our spot," notes Russ H. The park features a dedicated swim area and boat launch with ample trailer parking.
Old-growth forest hiking: The Lewis & Clark State Park Campground offers beautiful walking trails through ancient cedar forests. One camper shared, "This is a lovely park with beautiful trails that wind through very large, old growth cedar forests." The trails are well-marked and suitable for all hiking ability levels, with interpretive signs explaining the forest ecology.
Fishing at stocked ponds: Thousand Trails Paradise offers fishing in stocked ponds that children particularly enjoy. "My grandson loves coming here with us the two ponds they stock with fish," mentions John O. Fishing licenses aren't required for children under 15, but adults need Washington state fishing permits.
What campers like
Private, wooded sites: Ike Kinswa State Park Campground offers campsites with good separation between neighbors. "Large sites that are pretty private. Lots of shade and trees," reports Caitlyn R. Many campsites feature water views and have designated tent pads with level, prepared surfaces.
Clean facilities: Campgrounds around Onalaska maintain well-kept restrooms and shower facilities. At Elkamp Eastcreek, "The bathrooms were always clean. There's designated dish washing station and potable water station," according to Sarah Claire B. Most campgrounds charge $0.50-$1.00 for 3-5 minute showers.
Family activities: Recreation options range from swimming areas to game facilities. "This campground has an awesome swimming area with three pools, one 8ft deep, one 6ft, and one wading pool. Also has a large spa," mentions Pamela H. about Thousand Trails Paradise RV Campground. Many sites also feature playgrounds, basketball courts, and organized activities during summer months.
What you should know
Reservation requirements: Summer weekends fill quickly at campgrounds near Onalaska. "My favorite Washington State Park... the biggest downfall is that this place books up so fast. Make reservations early," advises Rick S. about Ike Kinswa. Most sites open reservations 9 months in advance with booking fees around $8-10.
Water conditions: Water quality and access varies seasonally. At Alder Lake, a camper noted, "The dam in Tacoma was partially drained causing a 'low tide' which exposed the dirt and poor beach area... usually when water is at normal level the beach is all sand and water is clean and clear." Call ahead to check current conditions, especially in late summer.
Cell reception: Winston Creek Campground and other remote sites have limited connectivity. "There was pretty much no cell service there from Verizon. I would occasionally get an alert of a new email, but was never able to refresh," reports Doug. Download offline maps before arrival as GPS signals can be unreliable.
Tips for camping with families
Playground access: Multiple campgrounds feature play equipment. At Seaquest State Park Campground, "My kids loved the addition of a playground. Many parks don't have this and it kept them entertained for hours," mentions Mary C. The playgrounds typically accommodate children ages 5-12 with nearby restroom facilities.
Junior Ranger programs: Educational activities run during summer months. "At night the campground had a great Junior Ranger program with a very enthusiastic park ranger that kept the almost 50 people/kids entertained," shares Ashley B. about Seaquest. Programs typically run Friday and Saturday evenings at 7:00pm during peak season.
Kid-friendly swimming: Several lakefront campgrounds offer protected swim areas. One visitor at Ike Kinswa State Park mentioned, "This is a beautiful camp ground on Mayfield lake there is something for everyone here. It has a large swimming area, hiking trails, playgrounds." Most swimming areas lack lifeguards, so parental supervision is required.
Tips from RVers
Site levelness varies: Check campground maps carefully when booking. "Some sites are beautiful with woods separating the sites and level spaces. Others are in the open with very slanted spaces," notes Ella T. about Thousand Trails Chehalis. Many campgrounds provide site-specific details online including length, width, and slope information.
Power reliability: Electrical service can fluctuate at certain campgrounds. "The power was really variable. Sometimes it would spike to 130 volts and then drop suddenly to 110," warns Marnie G. RVers should bring surge protectors and consider running on battery power if fluctuations occur.
Campsite access challenges: Navigate carefully when arriving at forested campgrounds. At Winston Creek, one RVer noted, "It was a bit tight to get our Jayco 174BH backed in due to the angle of the site and the path around the campground is very narrow. I would not want to come in here with anything much bigger than our little 20 footer." Call ahead to confirm turning radius measurements for larger rigs.
