We hiked the southwest trail early 7.30 am on a saturday in february. The route was fun, rugged/rocky,quite narrow and sometimes overgrown. The views are expansive hills and countryside. The "chairs" at the top are literally two chairs on a flat boulder strapped by ropes- we didnt do that since there was a small crowd waiting for it. It gives you an additional 3 meters vantage point- so we shrugged and returned. The hike itself was nice- long and gradual incline. I would say moderate- we had a couple of non-walkers who took 30 mins longer with multiple stops but they also made it in the end. Overall about 3 hours round trip for the slowest of us. There is some shade from the mountain itself if you go early enough but very little tree cover. For tourists: Do it only if you have a lot of time in san diego. For locals: its worth at least one hike for the views and your check list.
Parking is limited so go early in the day. I didnt see any restrooms around.
