On the northern tip of Eleuthera, surrounded by the Atlantic Ocean on one side and the Caribbean Sea on the other, the Glass Window Bridge dramatically rises from a natural rock formation. Covered in craggy cliffs and ridges, while periodically splashed by aggressive waves, the area exudes an eerie vibe. At Glass Window Bridge, Eleuthera narrows to an isthmus only as wide as the bridge itself, which is why it's called the narrowest place on earth. It's also the only place on the island that I fellt uneasy. Only later did I learn that rogue waves, sometimes as high as 100 feet, sometimes wash people and vehicles into the ocean.
