Please be advised that a forest tent caterpillar outbreak is currently at its peak at Hilliard's Bay Provincial Park.

This is a natural occurrence and refunds will not be issued if you choose to leave the campground early.

• If you cancel more than 72 hours before 2 p.m. on the scheduled arrival date, you will receive a full refund of all camping fees.

Forest tent caterpillars are a natural part of the boreal forest ecosystem. They are always present in the boreal forest, but about every 10 years they experience a population boom.

• Caterpillars are currently in their final instar stage, and are eating a lot of leaves in order to prepare for metamorphosis into their adult form, a brown moth.
• During a population boom, they can denude aspen and willow trees, their favourite foods. The trees generally survive and put out a flush of new leaves once the caterpillars are gone.
• The caterpillars are currently present in large numbers throughout the park, but will soon build their cocoons.
