The southeast slope is doable from the road but much of it is nasty scrub brush, loose crumbly rock and scree which makes the little drive though the forest from the north to within a stroll of the summit rocks a welcome alternative. Pinnacle Rock once had a fire lookout and there are rock steps leading up a short distance to the class 2 summit rocks which are much more solid than the rock below.
The views are quite outstanding for the minimal effort. North is hulking Goat and Snow Mountain, to the east Rupert Ridge, Evans Peak and Wolf Creek Ridge, to the south is Clear Lake with Mt. Konocti and Cobb Mtn. on the horizon. To the northwest is Windy Point and Horse Mtn. with the Mayacamas Range to the west beyond Clear Lake.
From the east: From the junction with Hwy. 53 just east of Clearlake Oaks take Hwy. 20 16 miles northwest along the lake shore to Bartlett Springs Road.
Drive up Bartlett Springs Road as it winds up for 6.1 miles to Bartlett Springs Summit. At that junction take forest road 16N01 which goes to the left and follow it 1.3 miles to a T in the road. Go right a short distance and park.
It is a short walk of less than half mile with a few hundred foot gain.
You can drive all the way to below the summit rocks if this last part of the road which is rutted is suitable for your vehicle.
