See the Getting There section of the main page for directions to the trailhead.
From the trailhead, take the Howlock Mountain trail east through a tunnel under Highway 138 and continue 1.1 miles to a junction with the Spruce Ridge Trail. Stay left here on Howlock Mountain Trail for another 2.4 miles just past Timothy Meadows to a junction with the Thielsen Creek Trail. Do NOT take this trail! Stay on HMT left another 3.5 miles to where the trail ends at a junction with the Pacific Crest Trail. Turn right and go maybe 100 yards to an open clearing where you can see the saddle ahead to aim for . Head due east (left off the PCT as you travel south) for the saddle cross country. Gain the saddle and walk the ridge left (north).
The ridge forms a "Y" here. Left ridge heads up to the pinnacle formation which you can scramble up the southwest side in a shallow gully (be careful-very loose and crappy plates) or you can also go to the northwest side of the pinnacle via the south and then west sides. SP'er cjwhat says the northwest side is better that the south/southwest side although still loose. Right ridge goes to the higher east summit and it achieved by scrambling up the ridge. Also LOOSE rock at the summit. Be careful!
Descend the same route. Total length of this route is about 15.5 miles round trip with 2700 feet of elevation gain.
None needed but take plenty of water, especially late in the season.
