There are, by the way, some beautiful places here in the north of Long Island. Large colonial-style villas, some with park-like gardens, are a sight to behold. The sophistication is reminiscent of places like Kampen on Sylt.

Montauk, by the way, has a walk-through lighthouse, which houses a small but fine museum that, among other things, explains the history of the Native Americans who once lived on Long Island.

Anyone visiting Long Island should definitely visit Montauk, as this end of the island is not only scenically very attractive - Pocahontas' life took place here, which is historically interesting. The "Hamptons" are also not far away. These places are beautiful: the picture-perfect east coast.
