""Having no trails for most of the route, the wardens require you to take an orienteering test before issuing permits and make you take along a transmitter. They also have you trace out a recommended route. Most people follow the Long Range Traverse which has campsites at 5 places and few follow the North Rim which has thick tuck and path-finding is challenging.""
Wow no trails And a test. You da-man. That's some rugged wilderness.
