The 114-year-old Weekapaug Inn in Rhode Island has just reopened after a five-year, $20 million restoration. Situated on a living estuary, the grounds are ideal for tapping into your inner nature lover: Go bird-watching, crabbing or clamming with its on-staff naturalist; then take a moonlit beach walk along tranquil Quonochontaug Pond. www.weekapauginn.com
