We're dog people. An island adventure with your pup makes for a magical experience and we encourage it. At 1 BSI, we want you and other guests on the ferry or island to know that everyone is safe and sound. So, we pre-screen all our pups with this form before giving permission for them to be island bound.

Our standard charge for pups is $30 per night per dog. Once approved, we will adjust your reservation for the charges.

There may be more than dog on the ferry or island at one time. Guests agree to keep their pets under control on 1 Big Sustainable Island and on the ferry. Guests agree to leash their dogs unless given permission otherwise. For guests at Naughty Dog Island, leashes are required on the ferry and no leashes are required once they are on the island. Guests will be responsible for damage and must be willing to hold the island owners harmless of liabilities caused by their dog(s).
