Mammoth's Unbound parks, lap by lap

Mammoth Mountain's Unbound Terrain Parks are one of the best-known park setups in North America. Mammoth's 25/26 fact sheet lists 10 parks, 2 halfpipes, 100+ jibs and 50+ jumps, spread across both sides of the mountain. Here's what each park is for and how to get to it.

Mammoth's parks page shows each park's open or closed status live. Park layouts, lifts, hours and ticket rules change through the season (and with the snow), so check the linked official page on the day you go.

Beginner: the Playgrounds

beginnersmall features

Disco, Wonderland & Eagle Playgrounds

Disco: Main Lodge, Discovery Chair (Chair 11) · Wonderland: Canyon Lodge, Chair 7 · Eagle: top of Eagle Express (Chair 15), on the run "Water Tank"

One small park at each base area: gentle rollers, small snow spines, mini boxes and jumps that grow as you go down. This is where to try your first box or first straight air without an audience of pros.

Intermediate

Forest Trail

Main Lodge, Unbound Express (Chair 6)

Mammoth calls it the stepping stone to its big parks: small to medium jumps and jibs, an 11-foot halfpipe, and the Twilight Zone banked slalom through the trees near the bottom. It's on the same chair as Main Park, so laps are short.

intermediatesurfy / skatey

Carousel

Roller Coaster Express (Chair 4)

Bowls, spines, hips and other snow shapes instead of a straight jump line. Mammoth describes it as surfy and skatey and says it takes patience to find the speed, which is exactly why transition riders love it.

Advanced & expert

advancedjumps + jibs

South Park

Roller Coaster Express (Chair 4)

Mammoth's longest park run, with big jump and jib lines. The resort's tip: it gets early light and is usually less affected by wind than the rest of the parks.

advancedrails, boxes, wallrides

Jibs & More

Next to South Park, Roller Coaster Express (Chair 4)

Rails, boxes and wallrides top to bottom plus snow transitions. It sits lower on the mountain, so it's the move when the weather up top isn't cooperating.

Snake Run

Off South Park, Roller Coaster Express (Chair 4)

Also called the "BMX Run": short, poppy jumps and berms that ride like a pump track. If you come from bikes or skate, this one will make sense straight away.

expertpro level

Main Park

Main Lodge, Unbound Express (Chair 6)

Mammoth's largest park: big jumps, technical rails and the 22-foot halfpipe. Advanced to pro riders only. The resort names the Unbound parks the official training ground for the U.S. Ski and Snowboard teams.

The Hemlocks

Hike-to area accessed via Chair 14

When the snow stacks up, the park crew builds kickers into natural step-downs here. It's big-mountain freestyle into powder, for expert riders only.
