Snorkeling is a definate yes in Aruba.....I would recommend De Palm Island. They pick you up at the Pier with an Air Conditioned bus. You take a 10-15 minute ride and then you arrive at their dock. You take a boat over to De Palm Island, only like 5 minutes. Once on the island (island is actually a large sand bar) you are walk to the beach and your all ready to snorkel. Everything is provieded for you, even an open bar and a lunch.
You can Scuba dive, Snuba, or Snorkel.....Snorkeling is fun but I would definatally recommend the Snuba its grrrrrrrreat
