Thanks for asking! There are a few campgrounds close to Highway 204 as you travel across the Blue Mountains. On the western side there is Camp Meadowwood Springs and as you move progressively east there is Woodward Campground near the summit and then further west Woodland Campground. A little further off the highway are two campgrounds, Target Meadows and Jubilee Lake Campground, with Jubilee being a local favorite that can be busy over summer weekends. You can find details about these campgrounds over at the US Forest Service here. Check out details about Elgin over at Travel Oregon here. Have a fun trip and stay!
