We have been to St. John twice and we always end up on Maho Bay. You will find the water warm and calm most always. The beach is sandy and smooth, framed with palm trees, and the aqua blue makes you know you are in paradise! The beach is popular, but we enjoyed watching the happy, lively people. Great snorkel spot for beginners, its easy and there are lots of surprises. Don't just go to the right side to snorkel, the center of the bay is actually awesome too. Get there before 10 AM or after 2PM or you won't find a place to park. Bring your ice chest and chairs, forget your book because Maho Bay is just to beautiful to take your eyes off it for a moment. Enjoy!
