This Mt. Williamson (8,214') refers to the USGS summit, the first from southeast to northwest on a ridge called Pleasant View Ridge. It is an easy hike up from Islip Saddle along the Pacific Crest Trail to a good use path that leads up to this summit. The top is barren and has fantastic views out top the coastal plain, other mountains, and desert at the same time.There is no summit register here, as the Sierra Club Hundred Peaks has it on Peak 8,244' which is a short ridge walk northwest of this one. This is my 2nd hike to both 8214 and 8244. Today, however, both were the 1st and 2nd of 6 peaks on a tough 8.5 mile day with 3600' gain out and back along Pleasant View Ridge over this, Peak 8,244' (the Sierra Club's Mt. Williamson), Peak 8248, Peak 8160 (listed here as Peak 8180), then down and up to Peak 7560 and Goodykoontz, and back in reverse. Beautiful day with absolutely no other hiker the entire journey!! The hike was tough to be sure, but peaceful. The scenery throughout is fantastic Stats for round-trip include the entire hike.
