Thousands of tiny toads begin trek to the forest

Thousands of Western toads are about to migrate from the lakeshore to forests surrounding Lost Lake.

These tiny amphibians start as tadpoles in warm shallow water before developing into toads and journeying to their future forested home. The migration typically starts hopping along the tail end of July, and occurs for two to three weeks.

But to get to their home safely, they need community support as they traverse trails, lawns and roads, facing dangers from bikes, cars and vehicles. To prevent disaster, the Resort Municipality (RMOW) has protective measures in place.

You’ll see informational signs, toad-guiding infrastructure, trails or lawns will be closed during active migration, and Lost Lake Access Road may close as well.

Lost Lake Park remains open and any closures would be announced on the RMOW’s website.

Anyone looking to help a toad out can volunteer with the 2025 Western toad migration by emailing [email protected].
