Follow Triangulation Peak Trail from the trailhead 2.1 miles to the summit.
Easy trail. Once at the summit, to get to Boca Cave, walk back down the trail a few hundred yards and over to the second smaller summit hump. Pick up a trail going down the side towards Jefferson, about a class 2 scramble, which goes down to a cliff edge. Follow the edge to the hidden cave. Take note, digging in or disturbing the cave is prohibited by law.
