Kind of deserted and spooky

1) not very busy at all, even on a Saturday. The trails are secluded and you don’t feel like you’re in San Diego :)
2) lots of wildflowers!
1) some muddy spots and sections of trail closed off, but easy enough to get around
2) no trash receptacles for dog poop so plan to pack it out with you

Overall, a fun challenging hike with some amazing views!

Really underrated trail and glad to see it on here. Parking is just in a neighborhood cul de sac, so very limited, and the first real climb is STEEP and full of loose rocks. Once you get up to the ridgeline, it's easy rolling hills until you get more into the park proper, and the last slog up black mountain is the fire road that most visitors know well. It's really the first mile and a half of this one that makes it- usually almost deserted and very quiet.
