Crossing
North Haven to southern Shelter Island on South Ferry.
South Ferry crosses from North Haven, just outside Sag Harbor, to Shelter Island. Bring a car for Mashomack Preserve, Sylvester Manor, beaches, and island restaurants; walk on only for a short crossing experience.

Ferry quick reference
South Ferry does not board at Long Wharf or in Sag Harbor village. Its crossing runs between North Haven and Shelter Island.
North Haven to southern Shelter Island on South Ferry.
At least four hours with one island stop; most visitors need a car.
Come back by mid- or late afternoon for a Sag Harbor waterfront evening.
Decision 1
Allow time for the short local drive and any vehicle queue. Confirm fares, payment, operating hours, and service notices directly with South Ferry.
Decision 2
Use Mashomack Preserve for trails and habitat, Sylvester Manor for history and grounds when open, or an island lunch plus scenic roads. These are different outings.
Decision 3
Continuing across Shelter Island to North Ferry and Greenport creates a larger loop. It is not a casual add-on to a short Sag Harbor morning.

Crossing choices
Drive to North Haven, ride over, take a brief island look, and return when the ferry itself is the attraction.
Bring the car, check preserve access, walk one appropriate trail, and return to Sag Harbor before late afternoon.
Cross late morning, drive a limited route, eat on Shelter Island, and skip the North Fork extension.
Continue to North Ferry and Greenport only when everyone accepts a full road-and-ferry day.
Leave after breakfast, cross with the car, use Mashomack Preserve as the main stop, and return to Sag Harbor by midafternoon. Confirm preserve access and trail information before boarding.
Cross late morning, drive a limited island loop, eat lunch, and return without adding the North Fork. This version keeps enough time for Long Wharf, a shower, and dinner back in Sag Harbor.
South Ferry plus North Ferry connects Sag Harbor to Greenport and the North Fork. Treat it as the day’s main road trip, check both ferry services, and do not promise a relaxed Sag Harbor afternoon afterward.
