Saint Helena Island
Saint Helena · Atlantic Ocean
One of the most remote islands on Earth, Saint Helena rises from the South Atlantic in pristine isolation, its underwater cliffs and seamounts drawing whale sharks, devil rays, and vast schools of yellowfin tuna through waters virtually untouched by dive tourism. The island's remoteness has preserved reef ecosystems that larger, more accessible destinations lost decades ago.
