The main trail begins at either the Overlord or the North Pangnirtung Fjord warden stations. From Overlord, it follows the east bank of the Weasel River to Windy Lake, where it crosses to the west bank and continues on to Summit and Glacier lakes. The secondary trails allow you to hike along the alternate banks of the river if you choose. In difficult terrain, the trail is marked by inukshuks, human-shaped cairns of rock. They indicate safe routes across moraines and rivers and routes that minimize damage to delicate environments.
