Thanks for the question! As you can imagine there are a ton of great places to camp and fish in Oregon. The following is a list of my favorites based on region.
Coast: Gold Beach or Loon Lake near Reedsport. There are some really cool coastal campgrounds in both locations. Tugman State Park and Umpqua Lighthouse both offer yurt rentals on site and are close to fishing sites. Lobster Creek Campground is a small site with access to both river fishing on the Rogue and proximity to saltwater fishing.
Southern Oregon: Summer Lake (Ana Reservoir) and Klamath Lake
These are just a few of the places in the state that you can fish and camp, but some of my favorites.
Let me know if I can help with any more questions. Fish on!
