This is looking towards the north end of Orient Beach.

The clothing optional part is on the southern end of the beach. Although, the only persons walking around without clothing, I saw, were at least over 65 years old! So, anyone excited about what they will see on the south end of Orient Beach, will sorely be dissapointed.
As you walk across the border that separates the northern "textile" section into the southern "clothing-optional" section of Orient Beach, there will be prominent warning signs. They also have signs saying cameras, camcorders, and cellphones w/cameras are prohibited in that clothing optional section. And you would really not have a reason to take a picture (considering the average age of those clothing optional participants).
I got to Orient beach via a taxi-van, which I picked-up at the taxi stand within walking distance of the cruiseship. The water-taxi pier is also nearby. But I think the water taxi's sole purpose is to ferry the cruise passengers from the cruise ship dock to the heart of downtown Phillipsburg (and no where else). I went on the taxi-van with other cruise ship passengers I did not meet before. So, they charged me only around $14 (the price going there alone would have been higher). The trip there wasn't pleasant IMHO. The middle of the island appears impoverished and the road there reflected that. So it was a long and sometimes bumpy ride, IMHO. But it was nice once I got there. The beach was beautiful.
And once it was time for me to head back, the same taxi vans were waiting eagerly in the parking lot near Orient Beach. Once again, I rode back to Phillipsburg with some strangers (passengers on another cruise ship) and saved money once again.
