The Maria Mitchell Aquarium & Sea Shop is a seasonal marine science center located directly on Nantucket Harbor. Operated by the Maria Mitchell Association, the aquarium features locally collected marine species, interactive touch tanks, educational exhibits, and family friendly science programming focused on Nantucket’s coastal ecosystems. Visitors can explore local sea life while learning about the island’s marine environment through hands on experiences and marine ecology programs.
Nantucket Walkabout offers guided nature walks and hiking tours exploring Nantucket’s protected landscapes, wildlife, geology, and natural history. Operating year round, the walks guide visitors through conservation lands and lesser known areas of the island while focusing on ecology, glacial history, native plants, and local wildlife. Tours are designed for visitors looking to experience Nantucket beyond the downtown historic district.
Built in 1846 at the height of Nantucket’s whaling prosperity, the Hadwen House is a grand Greek Revival mansion that offers a rare glimpse into the island’s wealthiest era. Now operated by the Nantucket Historical Association as a museum, it features period rooms, decorative arts exhibits, and a beautifully maintained Victorian garden. Located on Main Street, it’s one of the most striking historic homes open to the public on Nantucket.
