CB is one of the first public/free skateparks in SD county, it has lights, no fences and is free but is located right next to the police station so pad/helmet tickets are a real possibility (it cost me $200). The transitions are small/tight and the coping is pretty flat but the place definitely has some flow possibilities. It is basically 3 bowls connected with each bowl having different setups/obstacles. It has curbs on top of one bowl and curbs/ledges line the boarders of the place which add to the fun. If you like skating ditch like stuff, you will have fun here. If you are into bigger stuff, Encinitas is not far away.
Some will like it, some will not, but for North County SD, it is great to a have park that you can hit in the evenings without paying (except maybe the ticket thing). Younger skaters who live nearby are stoked on the place and it is certainly the best (ONLY) park within miles. If you are around that area (2 miles E. of I-5), check it out for yourself.
Carlsbad skatepark should be renamed Carls-really-bad skatepark. This place sucks, the tranny is too small, and the street oriented stuff is poorly designed. It is free and unsupervised, so it gets a 2 instead of a 1. Pads and helmets are required and, since it is located next to the police station, you can bet your ass that the pad rules are enforced. This place blows - only stop by if you happen to be in the hood.
15,000 square feet of small concrete. It is free, outdoors, and pads are a must! Open from 8 a.m. to 10 p.m. daily.
