We took a cab to Magens Bay and spent the day there. It cost us $4 per person to get in (baby was free). They charge $7 to rent a chair for the day. They also have a waitress that will take drink/lunch orders. We ordered a drink called "painkiller" and they were so good. We spent the day at this beach and had a wonderful time. The water was clear and calm and perfect for building sand castles.
We took a water taxi (located just off the pier) to a small but beautiful beach. Behind the beach was sprinkled with shopping/restraunts/bars. Each establishment would have chairs that you could rent on the beach. They all offer something different. The one we went with was $10.00 per person. That got us a chair/umbrella/wifi/bathroom/drink service/lunch service/and a very nice waiter that would cater to our every need.
This area was awesome!! I loved the island, the beach, the shops. It was so clean and beautiful. I will be returning to this island at some point in my future. I love St. Maarten!!
