theres no skate park in old town. Theres no park in pasadena. However, south pasadena park is fun. Also if you've seen clips of those curved ledges on IG, schmatty back tailed the whole thing, and ant travis front krooked - those are at Blair high school.
Youre not to far from Rosemead skatepark. Thats one of the best parks imo.
Enjoy, Pasadena. I lived there for two years until last month. Best city.
