Hiked this one by myself and ended up hiking a lot more than I first though I would. I wanted to hike the entire park and though I came close I ended up putting in far more time and miles that I originally intended.
The trails high on the ridge are by far the best in the park. If you visit and have limited time, go there and only there. The trails to the pond are not scenic and the pond at the end of the trail its named for suffers from lots of traffic noise as cars enter the Caldecott Tunnel.
The Bay Area Ridge Trail segment is near the lowest point in the park and was a bit muddy, even with the relatively sparse rainfall we've had lately.
I was concerned about the large gathering of people I could see and partly hear when I first arrived. They were gathered on a hill top at the opposite end of the park from where I started. I did the loop around Round Top and hoped that whatever was going on there would disperse by the time I worked my way over. As fortune would have it, they did indeed break up and head down towards the parking area when I headed in that direction.
