From Aqua Explorers:
WEST JETTY: Take the Long Island Expressway to Exit 65 South. Make a left on Montauk Highway, then a right on Ponquogue Avenue. Take this to the end and make a left on Shinnecock Avenue. Make a right turn on Foster Avenue. Cross over the Ponquogue Bridge and then make a left on Beach Road. Take this to the end and park in the lot named Charles F. Alterkirch Memorial Park. There is another small lot closer to the jetties, but parking is not allowed.

EAST JETTY: Take the Long Island Expressway to Exit 65 South. Make a left on Montauk Highway and drive east. Parking is limited and the walk is long. I have seen four-wheel-drive vehicles here, which definitely make things easier.
