Main Park

Accessible from Unbound Express (Chair 6)

CLOSED

Mammoth’s largest park has set the bar for pro-level terrain parks with its massive, perfectly sculpted jumps, technical rails and the 22-foot halfpipe. Countless professional skiers and snowboarders have launched their careers right here. Over the years, our park builders have continued to push the boundaries of creativity and fun while keeping the video-worthiness of Main Park alive and well. Watch Judd Henkes and Lyon Farrell smashing Main Park.

For expert skiers/riders only.

22-Foot Pipe

Main Park

CLOSED

This is the measuring stick for all others. Voted as the #1 pipe in the US by Transworld Snowboarding for several years, and being Shaun White's go-to pipe for dialing in new tricks are just a few feathers in its cap. Its ideal pitch and meticulous grooming standards make this monster a must ski/ride for any advanced shredder playing in the park.

South Park

Accessible from Roller Coaster Express (Chair 4)

CLOSED

There’s a reason pros come to this park to warm-up and spend their entire day lapping the South Park jump and jib lines. The long run length and flowy feel mixed with the early sun and lighter winds all combine to create a truly incredible terrain park experience. Check out Red Bull athlete Judd Henkes flowing through South Park.

Forest Trail

Accessible from Unbound Express (Chair 6)

CLOSED

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.

11-Foot Pipe

Forest Trail

CLOSED

Referred to by some as the "Nagano Pipe" (after the 1998 Olympics), this petite option can offer up some of the biggest smiles in your day. Loved by both kids and adults alike, you'll find this pipe at the bottom of Forest Trail, accessed by Unbound Express (Chair 6).

Jibs & More

Accessible from Roller Coaster Express (Chair 4)

CLOSED

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.
