Glacier Bay National Park is a sanctuary for Alaskan wildlife and may not be the best location to bring a pet. Pets are allowed on land in only a few select areas, and may not be left unattended. Your pet must be leashed or physically restrained at all times. They are not allowed on trails, beaches, or anywhere in the backcountry, with the exception of pets that remain on board private vessels on the water. 

Pets are allowed:

• On the Bartlett Cove Public Use Dock
• On the beach between the Bartlett Cove Public Use Dock and the National Park Service Administrative Dock
• Within 100 feet of Bartlett Cove Developed Area park roads or parking areas unless otherwise posted
• On a vessel on the water
