Tent campsites near Mossyrock, Washington range from basic primitive spots to walk-in sites situated at elevations between 800 and 4,000 feet. The region falls within the transition zone between temperate rainforest and drier eastern slopes, creating unique camping microclimates. Winter access to many campsites becomes difficult after November due to snow accumulation, particularly at sites closest to Mount St. Helens.
What to do
Fly fishing at Merrill Lake: The lake permits only fly fishing with special regulations in place to protect fish populations. Merrill Lake Campground offers tent-only camping with direct lake access. "Great for paddle boarding or kayaking. There's a boat launch. Best of all, it's free!" notes camper Kathy B.
Wildlife viewing at dawn: Early mornings provide opportunities to see deer and other wildlife at campgrounds throughout the Mossyrock area. "The wildlife (deer) that wandered through every morning was delightful," reports Kyle G. who camped at Paradise Pines.
Short nature hikes: Many camping areas include short trails suitable for morning or evening walks. "Very nice 1 mile hike is adjacent to the day use area," mentions Brooke S. about the trail at Merrill Lake, while another camper notes being "close to popular day hikes" in the region.
What campers like
Private tent sites: Campers frequently mention privacy as a key benefit at several locations. "This campground is best suited for tent camping, as there is only one RV site," writes a Merrill Lake visitor. At The Healing Farm, a camper shares that "The campsite itself was private, peaceful, and perfectly set up—complete with a fire pit and a hammock."
Early and late season availability: Many sites remain accessible when others have closed. "My friend and I were hiking a bunch of places in the Mt. Margaret Backcountry area... Really short drive from a bunch of nearby trails," notes Nastacia V. about Green River Horse Camp in late season.
River access points: Several camping areas provide private river access. "There is also a cool entrance to the river. Which was so peaceful and private! It was wonderful!" shares Kyle G. about their Mossyrock area camping experience.
What you should know
Vault toilet conditions: Toilet facilities vary widely between campgrounds, and many lack regular maintenance. "Bathrooms, bring your own toilet paper they are always out, but there are two port-a-potties," advises Shannon B. about Merrill Lake facilities. Another camper confirms: "Make sure to bring toilet paper, the bathroom seems to never be stocked."
Road conditions to dispersed sites: Forest roads leading to tent sites often deteriorate in wet conditions. "The road coming in the last 10 miles is rough in many spots. It's hard to see the bumps and dips in the road in the early evening," warns Chris about Mount St. Helens Dispersed Camping.
Weekend congestion: Popular camping areas fill quickly on summer weekends. "There are a lot of places for dispersed camping along FS-83, but they do get pretty full on nice weekends. Overall enjoyable camping, just expect neighbors," advises Karen about the Mount St. Helens area.
Tips for camping with families
Animal encounters: Some campgrounds offer unique animal experiences for children. "It is hard to find a place to be fun for younger children, but the healing farm was awesome. The kids was in Awh with all the animals and how they would let you walk up to them and interact with them," shares Rebecca A.
Cell service limitations: Most tent sites lack reliable phone coverage. "No cell service," notes Brooke S. about camping at Merrill Lake, which requires planning ahead for family communication needs.
Flat tent areas: Campsites with level ground make family setup easier. "The site was clean, and all sights are leveled out in a crushed rock space so be sure to bring a tarp for under your tent," recommends Shannon B. at Base Camp Mt St Helen's, where "You can camp at a beautiful campsite in Mt St Helen's close to the science learning center."
Tips from RVers
Limited RV access: Most tent campsites near Mossyrock cater primarily to tent campers with limited RV options. "This is a tents only campground," confirms Shannon B. about Merrill Lake. Another camper reports, "There are many spots to choose from for cars, trucks, and vans. It doesn't seem like it's designed for RV's and trailers."
Overnight parking alternatives: Some visitors find creative solutions when traditional sites are full. "I met up with some folks who were in tents and occupied the tent spots and spent the night in the parking lot in my van. Several other folks did this as well," shares Kathy B. about adapting to Merrill Lake's limited vehicle camping options.
Site approach challenges: Narrow forest roads can be difficult for larger vehicles. "The drive in is just off the highway and up a little hill, but my car had no problems with it," notes Danielle S., suggesting that smaller vehicles have better access to many camping locations in the region.
