Sightseeing around Mt. Saint Helens volcano in Washington State. Starting off at Centralia (not the fiery one) Chehalis then looping around the volcano with good enroute views of Mt. Rainier and Mt. Adams, finishing up at South West Washington Regional. I flew it at 7000 ft but you might get better views a little higher and if you want to fly over the crater you will need to be above 8000 ft.
