Oakley Skatepark is a 10,549 sq. ft. bowled concrete facility. No admission fee at this unsupervised skatepark. Safety gear not enforced. The centerpiece of this skatepark is a huge sub-surface bowl with 8-10 foot walls. In the middle sits a crazy L-shaped plateau with coping on the flat-top and a rounded hump on the remaining 2/3. Also a 6 stair set with a small transition at the bottom, a handrail + 2 other rails on the main platform, a couple jibs for slides and grinds and a nice roll-in area.
The cool thing about this park is its not just another playground skatepark. It's challenging to entertain most beginner/intermediate skill-sets. Most of the skateable concrete features are edged with coping or angle-iron. This helps prevent the inevitable chunkage from repeated grinds. There's also a long fun-box type thing along one edge for practicing your board-slides or smith-grinds also serves as an extension for the bowl. Skateparks like this are great for the kids in the area and are a great addition to the community.
