Jibs & More

Advanced
Closed

Just to the side of South Park, this park has nothing but metal and plastic protruding from the slope, in all shapes and sizes. When the weather isn't cooperating, the lower elevation of this park makes it a perfect place to spend the day hiking a down tube with or playing a game of “SKATE” on a box with some friends.

Snake Run

Advanced
Closed

Located just off South Park and also known as the "BMX Run," this park is defined by its short, poppy jumps, which remind many of riding a bike through a pump track. Flow is at the forefront here, with cruisey speed, rhythmic jumps, and mellow berms combining to create a hypnotic shred pace you never want to end. If Main Park is Metallica and South Park is Led Zeppelin, then Snake Run is Steely Dan – a soft-rock massage of the senses.

The Hemlocks

Expert
Closed

When the snow begins to stack up, the park crew heads out to the Hemlocks and starts building kickers to better utilize some of the landings on the slope. Mother Nature did some impressive work on the Hemlocks, but with a little help from our shovels, the place becomes a big-mountain freestyle paradise. Launching off a massive step-down into fresh powder is unlike anything else you can do no skis or snowboards.

Transition Park

Intermediate
Closed

Bowls, spines, hips, volcanoes, and other snow features combine to create our surrealist take on the terrain park. Surfy, skatey, and altogether original, the Transition Park takes time to master. Be patient with the transitions: it can take hours to dial in lines and fully realize where speed is hiding. Creating speed and maximizing flow are key when looking to take full advantage of this park.
