Yesterday Katherine and I did an 8.2 mile stretch of the PCT starting where it crosses CA S-22 (San Felipe Rd) and heading north to the Cal Fire station in Warner Springs on Hwy 79. We had to take two cars which is the problem with linear trails; a nice loop would have been easier logistically. We left Katherine's car on S-22 and hiked north to mine at Hwy 79. I'm not sure yet how much of San Diego County's portion of the PCT can be accomplished in a two-car, day hike fashion like this. At some point we'll have to spend the night on the trail but for now doing day hikes is just fine. In 2015 we did a two night, 25.5 mile section in the Laguna Mountain area (from Pioneer Mail to Scissors Crossing), described here. I know that from the southern terminus in Campo it's a 20 mile hike to Lake Morena (which is the closest spot we could park a car) and probably doable in a very long day but spending the night on the trail would be more fun. We'll see.
Being early April we came across 2 solo thru-hikers northbound to Canada. I imagine if we hiked southward we would have crossed paths with more as the normal route for them is south-to-north.
Just as we hit the trail I thought to download the AllTrails app to map our progress and act as a log for further PCT hikes. The green dot in the middle is the iconic and highly visited Eagle Rock where we stopped for lunch. All-in-All it's a pretty easy hike being fairly flat and very well marked.
