The Blue Grotto
The Blue GrottoThese smaller sea caverns located on the southwestern coast of the main island are a hidden gem. While they’re certainly not private, they don’t get nearly as many crowds as the Blue Lagoon or the Azure Window. What’s more, they’re about 10 minutes from the airport, making this a perfect first—or last—swim before landing or take-off. Just like at the Azure Window, weather-depending you can also hire small boats to take you out through the caves into the inlet. The best time of day to go is from early morning until about 1p.m. when the sunlight creates a phosphorescent-like glow deep into the sea, making it easy for those who aren’t diving to peek down below. Nearby, there are a few food trucks and casual eateries where you can sate your thirst or hunger after a dip and still enjoy the view.
