Pets must be leashed. There's no camping allowed. The sanctuary, nearly 400 acres including a buffer zone, is strictly protected because past experience has shown the harm that can be done. At more than 19 feet in circumference at chest height, it was Michigan's champion White Pine. As is the case for all Copper Harbor hikes and walks, sturdy shoes are recommended.
Trails are narrow and hilly in spots.
Bring something to drink, be prepared for bugs, and remember to take things at a pace that suits you.
