Trillium starts at the end of Blue Pulaski and Sleeping Jakes. It starts wide with some big berms with a few different line choices, then crosses a ski trail and thins into tight and natural singletrack. After a few turns, there is a steep wooden bridge over some water pipes that leads directly into a sharp bermed switchback.
Trillium then crosses another ski trail before dipping back into the woods onto short natural singletrack straightaways linked by great berms. This combination of natural singletrack with flowy berms continues the rest of trail until it ends at the bottom of the The Gronk near the base lodge and lift.
