The Toroweap (or Toroweep) overlook is the most exciting place I've visited on the Grand Canyon north rim thus far. It is in the western part of the canyon and can only be reached via 60 miles of dirt road. The first 50-odd miles were very well maintained when we visited but once one enters the national park the road becomes almost unmaintained and a vehicle with good clearance is required.
This pano was taken just before getting to the overlook proper. One can just start to make out where the Colorado river gorge is located.
