Believe the hype! We stayed in St. Thomas for a week and this was my favorite of the 5 beaches we visited. In my opinion, Magen's had the best combination of beautiful water, amenities, snorkeling (on the far left), scenery, and most of all, it wasn't too crowded. If you like the crowd, stay by the bar/snack bar, if you want more open beach, head to the left and the crowd thins out quickly. And make sure you fit in a stop for a milk shake at Udder Delight which also lives up the reviews and is on the road to Magen's bay.
