Overshot the turn off for the Three Sisters, so I went to peak 5057 first. Once up above I could see where I needed to go to get over to the Three Sisters. The hike description says to go 2 miles past West Boulder Saddle then go east. It's actually only about 1.4 miles. Two miles takes you almost to 5057. Depart the ridgeline trail 1.4 miles past West Boulder saddle at N33 24.385 W111 23.316 and go east about a third of a mile. That will get you to your destination. The cliffs are impressive! Very windy on the ridgeline at first, but calmed down considerably before leaving.
We tried climbing The Three Sisters but fell short by about a mile. This hike is a great workout if you want to gain elevation quickly and don't mind the pain in your knees the next day.
Carney Springs Road is very rough and I wouldn't recommend bringing a car unless you want to loose your oil pan. You need a high clearance vehicle to negotiate all the rocks strewn all over the road.
The first 1 1/4 miles to West Boulder Saddle gains about 900 feet in elevation over loose rock and dirt. This was a workout for my lungs on the way up and my knees on the way down. West Boulder Saddle give you a great view looking back towards Carney Springs Road and FS 77.
From West Boulder Saddle I felt like turning back when I saw the next climb. It looks very imposing from the Saddle, but I found the climb easier than the first 1 1/4 miles. You gain another 600 feet in elevation that mostly comes near the top. Once at the top, it's an easy walk along the Ridgeline Trail.
We bushwhacked our way to what we thought was the top of Three Sisters only to find ourselves on the smaller set of peaks next to Three Sisters. It was getting late, so we heading back down.
If you are looking for great views, I wouldn't recommend this climb over a Flatiron or Picacho climb. If you are looking for a workout without a crowd (we saw only 2 other hikers), this is a decent climb.
