We hiked a variation of this in reverse starting at Peralta and storming Cardiac Hill and then following Bluff springs to the terrible Terrapin trail. Its much nicer in this direction. Going the opposite way on our needle loop I thought my timepiece was gonna stop. After a brief walk on the Dutchman we strolled along the Cavalry trail to Boulder canyon trail and on to the Marina where our shuttle awaited us. We saw a few things and some people during our travels and thoroughly enjoyed our first through hike in the supes.
