Beach approachable by public transportation and can be connected with a visit of MOMA PS1 Art Installation (Katharina Grosse House) Also less crowed than other beaches in NYC.
Its quite a trip out there but so very worth it if you wanna have the very special beach-experience! You can go there by car and then take the ferry either to Pines or Cherry Grove (I would prefer Pines!) or you do all by public transportation - there a "getaway tickes" for 36Dollars and the transfer works really smooth - may even be faster than by car!
The naked baby dolls piled up in the front window of SEARCH & DESTROY is a good preview for what you’re in for. If you’re looking for something weird, this East Village shop is a good starting point. In addition to vintage clothing with a seriously punk rock lean, they also sell everything from sex toys to Manic Panic hair dye.
