We decided to take a taxi to Magen's Bay. It was $8pp each way for the taxi and then $4pp entry to the beach. The beach is beautiful! It is clean and there are life guards. There are also many trees, so natural shade is abundant. We got there fairly early so we didn't have a problem finding a spot under some trees. We really enjoyed this beach and had a great time swimming.
As other cruisers have stated, this port has a bit more nagging once you step off the ship. The island itself is very beautiful but you can tell it is not built up yet like other places such as St. Thomas or St. Maarten. We decided to take a taxi to Cockleshell Beach. The beach was on the other side of the island so we had a nice little tour driving over to it. It was $7pp each way for the taxi. There were limited chairs and umbrellas at the beach so we just found a spot in the sand. The water was great for swimming and it was beautiful to see the sister island, Nevis across the bay. This beach did have the occasional guy trying to get you to take a picture with a monkey or lady trying to give you an aloe massage. Nonetheless, we still enjoyed our time here.
We walked right off the ship and followed the road about 20 minutes to get to 'The Boat Yard.' The beach is beautiful and you only have to pay cover if you want to use the amenities of the Boat Yard. We swam in the water away from the restaurant/bar for a while until we wanted to find some shade. Then it was $12pp to get a chair/umbrella, free drink and a shuttle ride back to the ship. The drinks were not that strong but they were cheap. This also seems to be a favorite spot for the crew, so don't be surprised if you see some familiar faces enjoying their day off. There is also free wi-fi in the port terminal if you want to bring your smart phone/laptop on shore.
This tour included river tubing in the rain forest and a small hike to see the Emerald Pool. Our tour guide, Crisca, was very informative and excited to tell us about the island. The water was low in the river but we still enjoyed the tubing portion(just be careful as it is easy to run into/over rocks). It does require some physical ability as there's hiking up/down steps to the Emerald Pool and there are some rapids in the river. There was an older gentleman who flipped out of his inner tube and bumped his helmet on a rock but escaped unharmed.(and yet he felt compelled to share that he also nearly lost his swimming shorts in the incident!) Overall, it was fun and was worth the convenience of being taken around the island. We also got tiny little cups of rum punch. The 'tiny' part was not an issue as the punch was delicious and quite potent!
We loved this port the most. It seemed the most 'cruiser' friendly as the terminal had stations for taxis to line up for the different destinations. We took a taxi to Maho Beach aka Airport Beach. It was $9pp each way. There was traffic both there and back so make sure you allow enough time to travel. The beach has restaurants on both sides and as it's big draw, the airport runway is only feet away. Search youtube or google for some videos/pictures and see if it is something you would like. For us, we loved the free entertainment of incoming planes. It never got old to see the planes passing overhead, especially the big jets! The bar lists the flight times for the big jets on a chalkboard surfboard. The day we were there they mainly started about 11:30am and went until about 4:30pm. The bar itself had great drinks and food. So whether you were swimming, sitting on the beach or grabbing a drink, it was easy to pass the day here. Lots of fun!
