It’s that time of year again – thousands of tiny Western “toadlets” are making the migration from the shores of Lost Lake to the nearby forest.

To protect the toads, Lost Lake Beach and the surrounding lawn areas, as well as the access road have been closed until further notice. The Lost Lake Shuttle will not be running until the park is re-opened.

The Lost Lake Loop trail, dog beach, and docks remain open to foot and bike traffic, however pedestrians are urged to be very cautious if they come to witness the migration. With tiny toads all over the place, treading carefully is imperative.

The Resort Municipality of Whistler (RMOW) has been monitoring the Lost Lake toad population for the past 11 years and implementing measures to protect this vital population. Last year, a record number of breeding Western toad pairs were observed in the lake.

Following the breeding season, thousands of tadpoles develop along the lake shore until they have grown into tiny toadlets capable of making the migration. In a press release, RMOW writes, “This migration can often appear as a moving carpet, as tens of thousands of dime-sized toadlets make their way across Lost Lake Park.”
