Gray Butte, Coleand Warner Loops
The fun trail combinations of the Gray Butte, Cole and Warner Loops are on BLM land east of the park. When you come out at the Burma Road Trail summit off the Summit Trail, you take the Gray Butte Trail to connect to them.
Here's one 10.3 mile option starting from the Welcome Center, doing the Summit Trail to the Skull Hollow Campground. At that point you can run back the way you came or via the 8-mile road to the park.
