Trailhead: West entrance of Pinnacles NP. Drive to the end of the road, and park. CA-146 is a narrow and windy road, not good for big vehicles. Also a number of routes starting from the East side of the park.
Website: SOTA Site
Maps: I like the Tom Harrison maps. You can get a low quality (not good enough for off-trail travel) map for free at the entrance. KB1KXL SOTA Hikes map
Route: From West side: Juniper Canyon Trail, Tunnel Trail, then follow climbers' paths. From the East side: consult a map. Many choices, including loops.
Red Tape: The area can be closed to protect nesting raptors.
