The Echo Canyon trail is 1.2 miles long (one way) and 1,264 feet to the summit at 2,704 feet.
Time going up was 45 minutes and down was 21 minutes with a 15 minute rest at the top.
The picture shows a rail to help hikers up and down the extremely steep parts. This is one of two rails. On the was down I sat on the rail and slid instead of walking.
The other way of getting to the top of Camelback Mountain is by approaching it from the east side on the Cholla Trail which is longer (1.5 miles) but not as steep.
I'm planning to hike with some friends from the south to the north rim of the Grand Canyon later this year and so I'm going to have to do plenty more of this type of hiking to train for that.
