Two nights. Parked at the East Rim TH and took a shuttle to Lee Pass. We camped up on an awesome ridge in Wildcat Canyon approximately 0.5 miles south of the spring and again on the East Rim trail just past Stave Spring. We were there during a stormy cold snap, but the weather turned out to be perfect for hiking and the fog/clouds made for dramatic views. Water sources were good, only saw a couple of runners and two other groups on the trail, lots of beautiful wild flowers in bloom, and a lot of muddy trail. This traverse is awesome, highly recommended!
Looks awesome, thanks for sharing!
