Castle Peak Bouldering

From I-80, take the Castle Peak/Boreal Ridge exit. Head north, and either park at the trailhead parking area with everyone else or continue on a rough dirt road (high-clearance vehicle advised, but not strictly necessary), taking your first left past the gate. From here, stay on the main dirt road, passing at least one left-hand turn (do not turn here) and park at an obvious pullout about 0.6 miles in. At this point, you can use a high-clearance vehicle to drive in about 100 yards more if you want to; either way, take a rutted-out (often muddy) road left from the parking pullout to a large meadow. Skirt along the left side of the meadow, following an obvious trail west, across a creek and up and down a little and you'll start finding boulders. Stay on the trail at all times, the trail definitely leads to the boulders. It's about 15-20 minutes to the Under Queen Boulders. Once you have reached the Under Queens, Treasure Cove is another 300yards West; the trail is obvious.
