🖼️ New England Aquarium

The Giant Ocean Tank is the collection's crown jewel — a 200,000-gallon cylindrical Caribbean coral reef rising four stories through the building's core, historically home to Myrtle the green sea turtle, the aquarium's most beloved resident who lived here for over four decades. Spiral the ramp to catch sand tiger sharks, moray eels, barracuda, and southern stingrays layered at every depth. Do not miss the Amazon rainforest gallery, a humid biome of piranhas, poison dart frogs, anacondas, and free-flying tropical birds, or the African penguin colony near the entrance, where over 80 birds inhabit a rocky island exhibit and are known individually by keepers. The Edge of the Sea touch tank recreates a Gulf of Maine tidepool where visitors handle live sea stars, horseshoe crabs, and sea urchins under staff guidance. Seek out the jellyfish gallery, where backlit moon jellies drift in hypnotic columns, and the shark and ray touch tank on the West Wing. Outside, the Atlantic harbor seal exhibit flanks the main entrance and is free to view from the plaza without admission. Behind the exhibits, the aquarium's Anderson Cabot Center for Ocean Life anchors one of the Atlantic coast's most active marine rescue programs, rehabilitating cold-stunned sea turtles and stranded seals each year — the conservation science that gives the whole collection its purpose and ties the exhibits directly to the working harbor that made Boston a maritime capital.

The aquarium offers several guided experiences that reveal what self-guided visitors miss. The Behind-the-Scenes Tour ($75, roughly 90 minutes) takes small groups above the Giant Ocean Tank to the open-topped viewing platform, through the food-preparation galley, and into the animal care areas, where staff explain the veterinary work behind treating rescued sea turtles and seals. Throughout the day, divers enter the Giant Ocean Tank for feeding presentations, narrating live through underwater speakers and answering questions about the reef's inhabitants — a free, informal tour that transforms spectacle into science. Naturalist-guided whale watching trips depart the adjoining dock April through October; onboard educators from the aquarium's research team help spot and identify individual humpback whales at Stellwagen Bank National Marine Sanctuary by their tail-fluke patterns and explain feeding behaviors like bubble-net hunting. For families, staff-led touch-tank sessions at the Edge of the Sea exhibit turn a quick look into a hands-on lesson about Gulf of Maine tidepool life. Members and school groups can book specialized tours covering the aquarium's rescue and conservation work, including its role in shaping federal marine policy. Arrive early and check the posted daily schedule at the entrance, since dive presentations and feedings run at fixed times and the most popular tours sell out on summer weekends and school vacation weeks. Many Boston walking-tour operators fold the aquarium and a Central Wharf whale watch into a wider harbor-and-waterfront itinerary, so ask your guide about combining it with the nearby Faneuil Hall marketplace.
