Dispersed camping near Cougar, Washington provides an economical base for exploring Mount St. Helens National Volcanic Monument. The area sits at approximately 700 feet elevation but climbs rapidly into forested mountainous terrain with temperatures typically ranging 50-80°F in summer and 30-50°F in winter. While established campgrounds offer amenities like showers and picnic tables, numerous free dispersed sites require self-sufficient preparation but reward with greater solitude.
What to do
Volcanic exploration: 45 minutes from town. The south side of Mount St. Helens offers unique volcanic features accessible from camping areas. Cougar Park & Campground provides convenient access to volcanic attractions. "Up the road is Lava Canyon, where there are toilets if you need," notes camper Danielle S., who used the area as a staging point for exploring the mountain.
Fly fishing: Technical challenge. Merrill Lake restricts fishing to fly fishing only, creating a peaceful angling experience without motorized boats. "Boats and boat ramps are right there... View is gorgeous of the lake and fishing is great. Fly fish only," reports Shannon B. about the technical fishing opportunities.
Night sky viewing: Far from light pollution. The remote location offers excellent stargazing opportunities. "Very peaceful. Far enough out of town to be peaceful, and see the stars," says Jessie S. about camping in the area. Bring warm layers as temperatures drop significantly after sunset even in summer.

What you should know
Limited cell service: Plan ahead. Most campgrounds around Cougar have minimal or no cell reception. Come prepared with offline maps and information. "No cell service," notes Brooke S. about camping in the area, making advance planning essential.
Weather variability: Pack layers. Mountain weather changes rapidly throughout the day. "The weather does change very fast in the park so bring extra layers," advises Kevin T. from his experience at Cougar Park. Morning temperatures can be 40°F colder than afternoon highs.
Fire restrictions: Check before arrival. Seasonal fire restrictions vary. "At this time. There isnt any camp fires allowed," reports S. Renae M. about Sunset Falls Campground. Contact local ranger stations for current fire regulations, particularly during late summer.
Tips for camping with families
Swimming areas: Kid-friendly spots. Several campgrounds offer designated swimming areas for families. Battle Ground Lake State Park Campground features "a swim area roped off, and a small sand area for the kids to play," according to Wendy C. The lake water warms enough for comfortable swimming by mid-summer.
Playground access: Energy outlets. Some campgrounds provide playground equipment for children. "There's fishing, swimming, a playground, showers and great camp sites!" shares DawnMarie T. about Beaver Bay Campground. These facilities help keep children engaged between hiking adventures.
Camp store conveniences: Last-minute supplies. Certain campgrounds maintain stores with essential items. "They have a camp store open for snacks and they have flushable bathrooms!" mentions Tiffany M. about Battle Ground Lake State Park, saving families from long supply runs when necessities run low.
Tips from RVers
Limited hookups: Plan for self-sufficiency. Many campgrounds offer partial hookups only. Lone Fir Resort provides more complete services. "We camped in an rv spot with our trailer. They are very strict about quiet hours. There is a pool, gameroom, restaurant and store," reports Michael K. These amenities make it suitable for less self-contained RVs.
Dump station locations: Know before you go. Not all campgrounds provide dump stations. "This campground is an amazing dry campground, extremely clean, great clean bathrooms, easy access to the reservoir to swim. With an RV dump and potable water," explains Cherie C. about Swift Forest Camp. Plan your waste management accordingly.
Site size considerations: Length restrictions apply. Many forested campgrounds have limited turning radius and overhead clearance. "There are several awesome trails you can take right from the campground and there is a campground trail that guides you around the whole campground area," notes Kelcie T. about Kalama Horse Camp, which accommodates smaller RVs despite its primary purpose for equestrian camping.
