When Pigs Fly (WPF) is the signature trail of Burns Lake's Boer Mountain Recreation Site — a must-ride for every visitor to the network. Designed by Gravity Logic from Whistler Bike Park fame, WPF is a fun, flowy blue-rated descent that delivers exactly what you'd expect from a world-class trail builder: pure flow, perfectly sculpted berms, and momentum-building terrain that keeps you grinning from top to bottom. The trail is part of the descent options from the top of Boer Mountain and, together with Charlotte's Web and other trails, culminates in the spectacular Pierce Hofer Memorial — a 2,000+ square foot wall ride adjacent to the Kager Lake parking lot. The Pierce Hofer Memorial was built in memory of Pierce Hofer, a well-loved young man from the community tragically lost in a motor vehicle accident. WPF finishes via the Wee Piggy Skills Park back to the parking lot. Rated moderate. Located on the traditional territory of the Lake Babine Nation and Ts'il Kaz Koh.
