For first timers, park along Invergordon Rd, south of the turn on Cholla Lane. Do not park on Cholla. It will make the local hillside folk quite sour and your car might be towed. Walk up and access the trail from Cholla. And, voilĂ - your warm up is complete!
The reviews are correct. This side of Camelback mountain is an easier hike compared to Echo Canyon. The terrain here is somewhat more slippery and the rock separations will test your balance and ankle strength. Be sure to wear appropriate shoes to keep you steady. Take your time and you can choose your own path towards the top.
One of the best times to come is before sunrise. Nearby parking should still be available and you shouldn't need a headlamp. I would shoot for a 5am start on the trailhead to get your money's worth. The view will be wonderful.
Advanced Challenge: Do an "over and back." Head up Cholla and go down Echo Canyon. Drink some water and turn right 'round, baby, right 'round. Back up Echo and down to where you started.
Happy Hiking Phoenix!
