About this bike park
Tamarack Resort's bike park above Lake Cascade anchors a nearly 50-mile trail network with lift-served downhill runs plus cross-country riding, and hosted a Big Mountain Enduro stop in July 2025. The start of its 2026 lift-served season is on hold after a Memorial Day 2026 windstorm damaged a lift tower requiring replacement.
