It is reached by ferry from Greenport, about eight minutes, or from North Haven, about five. If you want to live on it, see Shelter Island rentals on Hamptons Key.

Healthcare and services
Stony Brook Eastern Long Island Hospital in Greenport describes itself as accessible by land, sea and air, with a heliport and an emergency dock; see healthcare. The Shelter Island Public Library gives Full Access cards at no cost to residents with proof of a local address and to renters with proof of lease, as well as their children aged three and over.
Trash uses Town bags. The Town’s Recycling & Transfer Station runs a hazardous-waste drop-off on the first Saturday of every month, 9 a.m. to 1 p.m., and the Town’s code sets fines of $50 to $1,000 for violations; see the transfer station guide.
