While you're hanging out in the Boston Public Garden, take a ride on the city's signature Swan Boats. The boats are the only ones of their kind in the world and they float the waters of the Public Garden lagoon. A ride on one of these boats is the best way to see all of the attractions in and around America's first botanical garden.
Dive deep into ocean exploration at the New England Aquarium. You'll see a variety of sea creatures living in simulated versions of their natural habitats through exhibits like the Amazon Rainforest, the Gulf of Maine, the Pacific Reef Community, the Edge of the Sea, and many others. A few of the animals you will see include sharks, sting rays, sea turtles, seals, jelly fish, penguins, octopuses, and dolphins.
Rent a canoe or kayak from the South Bridge Boat House for a day of fun on the water. Set sail on your excursion and explore the waters of the Assabet, Sudbury, and Concord rivers. If you don't feel like piloting your own adventure, look into enjoying a river cruise aboard a pontoon boat.
