After you’re comfortable in the Playgrounds, Forest Trail is the next step. Newly re-designed and more flowy than ever, the perfectly placed jumps and jibs make this a favorite among intermediate groms, moms and dads who rip.

This is the perfect stepping-stone on your way to our expert and pro-level parks. Well-proportioned jumps and jibs with small gaps allow for a fun and natural way to progress your skills. With Forest Trail being easily accessed from Chair 6, banging out a ton of laps in a short amount of time is a snap. Be sure to check out the Twilight Zone towards the bottom of the park for a super fun banked slalom through the trees.

Jibs & More

Jibs & More

Accessible from Roller Coaster Express (Chair 4) 

OPEN  |  11 Medium  Jibs 

Just like the name implies this park is all about steel and snow jibs. A great alternative when the weather isn't cooperating or if you're looking to dial in a specific trick. 

Whether the wind is blowing or the sun is shining, Jibs & More is guaranteed to be going off. 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.
