This is a point-to-point route starting at FR18, going up and over "The Dome," and ending at East Lake Campground. Along the way, you drive on the rim of a volcanic dome and go through the Newberry Wildlife Refuge. The views and scenery are amazing, and this is a great drive whether you have a destination in mind or not! There are also some pretty epic primitive camping options in addition to all of the camping areas around East and Paulina Lakes.
There are rocky areas with steep inclines. High clearance and all or 4WD may be necessary, depending on your vehicle.
