Aruba has decent snorkeling but not the crystal clear waters of other Caribbean islands. Malmok is one of the clearest and it's easily accessible. Nice if you have a rental car. Good place to spend a couple of hours snorkelng along the reef and cliffs. There are some palapa spots, but generally taken by locals. Bring towels and rough it by placing them on the rocks. Safe area and easy to snorkel. Lots of fish and if you look close, you'll see eels and crabs along the walls and reefs.
