Best Camping Spots for Solo Travelers in the Pacific Northwest?

I've been thinking about camping a lot lately, and I'd love to share some of my favorite camping spots with the community, but first I want to hear from you guys 😊. I'm planning a solo trip to the Pacific Northwest and I'm looking for some recommendations on the best spots to pitch a tent. I've heard great things about the Olympic National Park, but I've also been considering the Columbia River Gorge. Maybe someone has some experience with camping in these areas? I'm looking for spots that are relatively secluded, but still have access to basic amenities like restrooms and potable water. I've got a pretty versatile tent, so I'm not too worried about the terrain, but it's always nice to have some flat ground 😊. I've been camping in these areas for years, and I've got some favorite spots that I like to return to, but I'm always looking to try out new ones. So, what are your go-to camping spots in the Pacific Northwest? Do you have any favorite campsites or tips for solo travelers? I'd love to hear about your experiences and get some new ideas for my next trip 🏕️💚
