The is a small campground (3 sites) located along Eightmile Creek.
If you’re on the Eastside of Mt Hood this is a good campground to head too, if you like primitive and remote. The campground is a lot bigger than I thought it would be, I think there’s 21 sites. Not a lot happening. I was shocked it’s $21 to camp, thought it would be cheaper. There’s several day use spots in the campground too, for $5 (or free if the NW Forest Pass). Hiking trails nearby, that’s why I was there.
We were staying at Eightmile Crossing Campground, so I came down the half-mile trail to walk around Lower Eightmile for a bit. I think it might reach 4-star status if there wasn't a lot of traffic down the dirt road the 2-3 campsites are along, or you didn't get the airplane noise like you do at Eightmile Crossing, but I didn't stay overnight to find out. No traffic or traffic noise during the 30 minutes I was there, though. Fantastic trees/greenery and a healthy stream, plus wide-open spaces and a wide road make for great star-gazing opportunities. Don't forget about the nearby Bald Butte hike, a tougher but relatively off-the-map route ending with humongous views.
