๐ฒ๐ Ready for a volcanic RV adventure? ๐๐ฒ
If you haven't taken your rig to the shadow of Mount St. Helens, you are missing out on one of the most awe-inspiring landscapes in Washington State! From dense, ancient forests to the striking, recovering blast zone, the camping around this iconic volcano is truly next-level.
Because the roads do not connect the North and South sides of the mountain, picking the right basecamp for your itinerary is key! Here are a few top-tier RV spots to check out for your 2026 camping season:
๐ **Seaquest State Park (West/North Side Approach)**
Nestled in lush woodland, this state park is a classic PNW destination. It features spacious loops (including full hookups) and a pedestrian tunnel that takes you right to the Mount St. Helens Visitor Center at Silver Lake. It's the perfect launchpad for a scenic drive up the Spirit Lake Highway (SR-504).
๐ **Eco Park Resort (North Side Approach)**
Looking to get closer to the blast zone? This rugged, eco-friendly private resort at Mile Marker 24 on SR-504 offers RV sites, cabins, and beautiful views. Itโs an incredible basecamp for exploring the nearby Science and Learning Center at Coldwater Lake and hiking the Hummocks Trail.
๐ **Cougar RV Park & Campground (South Side Approach)**
If you want to explore the famous Ape Cave (the third-longest lava tube in North America) or hit the waters of the Yale and Merwin reservoirs, this is your spot! Located in the small town of Cougar, it offers upgraded RV sites with electricity and easy access to the mountain's lush, unblasted southern wilderness.
๐ **Lone Fir Resort (South Side Approach)**
Another fantastic South Side option boasting spacious 45-foot full-hookup sites. It's incredibly close to the Mount St. Helens climbing bivouac and the Lewis River recreation areas.
**A Quick Pro-Tip Before You Go:** > *Always check WSDOT and Forest Service road conditions before you head up! The South Side is heavily forested and great for caving and reservoir boating, while the North Side (SR-504) is where you want to go to see the dramatic crater, the landslide debris, and the Spirit Lake area.
