Shaw Millenium Skatepark - Calgary, Alberta, Canada Even though it is paved, this park is worth mentioning for any rider. Calgary's Millenium Park is the LARGEST OUTDOOR PUBLIC SKATEPARK IN THE WORLD! (currently over 63,000sq ft, soon to be over 90,000 with the addition of a snake course) It is open 24/7, and is free for all users. While primarily for skateboarding, all sports are allowed here. Millenium Park has terrain for the beginner, right up to a giant full-pipe and all kinds of ramps n' rails for the expert rider. This park is a must see!! It was a highlight of the Tony Hawk Gigantic Skatepark Tour as well. Many extreme events are held here, and it is only a matter of time before mountainboarding becomes featured.
Time for EXTREME! Polo. Hey, skater boy, you better get out of the way when you are between the ball and a few tons of galloping polo ponies.
