September 2, 2021 - Mount Sproatt & Rainbow Lake Alpine Trails

** UPDATE**

Trails are no longer closed due to Grizzly Bear activity. The trails will reopen in 2022 when snow levels allow.

Bear Alert Update (Sept 1^st): Mount Sproatt and Rainbow Lake Trails

Due to increased Grizzly bear activity in the area the Alpine trails network on Mount Sproatt and Rainbow Lake closures are in place for the following trails:

Rainbow Lake Hiking Trail and Hanging Lake Campground area

Into the Mystic (above Less Trail)
With A Twist
Pot Of Gold
Ninja Loop
Upper Lord of the Squirrels
Happy Hour
Last Call
Rush Hour
On the Rocks

This closure will be in place until further notice.The Conservation Officer Service and the RMOW will continue to monitor the area.

The closure is aligned with, and supported by, the RMOW’s Human-Grizzly Bear Conflict Mitigation Strategy.  The Strategy aims to minimize impacts of recreation trail use on grizzly bear habitat and identify actions to minimize human interactions on the alpine trail system.

The alpine areas of Mount Sproatt and Rainbow Lake provide ideal foraging habitat for the Grizzly Bears, especially in late summer/ early fall when the bears are entering the hyperphagia period.

This is when the bears  need to feed continuously in order to prepare for winter hibernation. Human interactions during this time cause disruptions to their feeding which can lead to aggressive behavior.

About British Columbia’s grizzly bears

Grizzly bears are a significant part of the BC landscape. There are approximately 15,000 grizzly bears in British Columbia which is about a quarter of the North American population. Of the 56 grizzly bear population units still in existence in BC, nine are classified as threatened.

Grizzly bears are an important umbrella species that sustain many other species. They play a key role in maintaining healthy ecosystems, for example, by distributing salmon nutrients into forests and transporting seeds through their feces.

Habitat quality and population density vary widely across the province. Currently listed as threatened, Grizzly bears in Whistler are part of the Squamish-Lillooet Grizzly Bear Population Unit and are managed for recovery by the Province of British Columbia.

The cumulative effects of human development are the greatest threat to grizzly bears in BC.   As a result, the RMOW Council passed a resolution supporting grizzly bear recovery, and the Human-Grizzly Bear Conflict Mitgation Strategy was developed in partnership with the Province of British Columbia and the Conservation Officer Service.
