Lavallée Lake, in the remote northern section of the park, hosts one of the continent's most significant colonies of American white pelicans — a species that nests on an island in the lake and fishes its waters through the summer. Reaching the lake requires a multi-day canoe trip or floatplane charter; it is not accessible by road or day hike.
For most visitors, the pelicans visible at Waskesiu Lake and along the park's waterways — birds commuting between feeding grounds — are a more practical encounter. The sight of a dozen of these enormous white birds soaring in a thermal over a boreal lake is not easily forgotten.
