Torrey pines high school has that slight downhill manny pad that’s in a million skate videos. Super fun.
Encanto elementary has some fun ledges you can skate in a line. They’re almost knee high
Ruocco park in downtown SD has these rocks you can skate over and wallie. It’s a fun mess around spot that the sk8mafia dudes skate a lot
All three spots are roughly 10-15 minutes from Linda Vista skatepark. As far as skateparks go, I’d recommend City Heights, lemon Grove, and Kimball park. Pacific Highlands ranch skatepark is a little further out but it’s a fun low-impact park with a concrete pump track next door
