There are more comfortable ways for your pets to travel to Nantucket! By water: Dogs and cats sail from Hyannis at no extra cost aboard both HyLine Cruises and Steamship Authority. Leashes, but not kennels, are required for dogs. By air: Flying with your pet to Nantucket is a breeze with Cape Air and Nantucket Airlines. An additional fee of only $10 per animal each way, as well as an advance reservation, is required. Cats must be in a kennel but dogs flying to ACK from Hyannis or New Bedford can sit right in the cabin with you! Once you've arrived, getting around the island proves to be just as easy. Well-behaved and leashed dogs are also allowed on the public transit system, the WAVE. And if you're looking for pet-friendly accommodations on Nantucket, look no further than The Cottages & Lofts at The Boat Basin.
