There is a regulated taxi stand right by the pier . It is 7 dollars to Orient beach( with at least 4 to a taxi( van) just wait till there are enough to go at that price, happens quick.
Taxi ride is about 15 minutes.Orient beach is on the other side of the island( small island)
As for the clothing optional thing, don't worry we only saw one of two aging saggy men in g strings( ugly!) and one topless girl. No big deal.Don't look if you don't want to, BUT if you continue farther down the beach ( and yes there is a warning sign) you will see more of it. It is quite a walk so you won't " accidently " wander into a nudist colony
Taxi are always there to take you back.
We thought the beach was lovely, and yes shop around for best prices, we got an umbrella and two lounge chairs for 15 bucks but if we had just walked down the beach abit further we could have had that plus a free drink each for 14 dollars. Also we got our first beers for $ 3.50 but our second beers ( I walked down the beach again) for 2 bucks each.
It was the best day, wish we were back there!
