Think denver, but suckier...another architerra park. As they have now designed a half-dozen parks around Denver, I think they have become cocky and thrown any new skateboarder design imput in the garbage. Their skatepark designs are not becoming more challenging or progressive, but their mulching is beautiful! Their standalone bowl designs is their only decent element they can put out - Castle Rock's bowl is alright, but the street course is another example of their typical clusterfuck design technique - horrible geometry in the rails and ledges and dead end walls where a bowl corner should have been placed. The separate kiddie area is a good idea for this park and any other skatepark. Castle Rock is free, no pads, and open from dawn to eleven or so at night, thanks to the powerful ass stadium lights. Stop here if you ain't in a hurry. Otherwise, skip this place and keep heading south to Trinidad!
