Sag Harbor is a village in two towns, and in winter it works as a walking base. This plan uses only venues that post their own hours, and leaves meals to Eat Hamptons’ Sag Harbor page, which checks winter hours for restaurants. If you want to see what a longer stay would be like, look at Sag Harbor rentals on a monthly term.
Saturday
Morning at the refuge. The Elizabeth A. Morton National Wildlife Refuge, 187 acres on Jessup’s Neck near Sag Harbor, is open from half an hour before sunrise until half an hour after sunset. No pets are allowed, and part of the beach is closed April to August. Sunset in mid-December is about 4:22 p.m.; plan the walk for the middle of the day. Check the tick guidance first.
Afternoon at the library. The John Jermain Memorial Library at 201 Main Street, (631) 725-0049, is Sag Harbor’s public library. Its homepage describes a free Wi-Fi hotspot and seasonal library cards for summer visitors; residents of the Sag Harbor school district get cards free with a photo ID and proof of address. See Hamptons libraries.
Evening at the cinema. Sag Harbor Cinema is a triplex in the village. Its website lists the current screenings and the gallery on its third floor.
Sunday
Across the water. The South Ferry runs between North Haven and Shelter Island, about five minutes, according to Wikipedia. On the island, Mashomack Preserve is open dawn to dusk, seven days a week, except for January 2027, when the Nature Conservancy says it is closed to visitors. Ferry schedules are on Hamptons Commute.
