A short drive north of the village of Palmeira on the island of Sal, a hidden gem awaits — a small inlet along the rocky coast unveils a natural wonder. At the opportune time, preferably in the morning, sunlight filters through a hole in the rocks, transforming the scene into a mesmerising display resembling a bright blue eye. The juxtaposition of the vibrant blue water and the frothy white waves crashing against jagged rocks creates a stunning spectacle. Just above this sight, there is a small swimming hole with calmer waters from which to enjoy it.

Goethe House is the birthplace and childhood home of Johann Wolfgang von Goethe, born in 1749. Step inside to see the poet's study on the third floor, where Goethe wrote early works, including The Sorrows of Young Werther and began Faust.

Situated on the southern tip of Florida, the Everglades is a vast wetland preserve spanning 1.5 million acres. It is the only subtropical wetland in North America and the only place in the world where alligators and crocodiles live side by side. This expansive ecosystem is home to many endangered species, including the leatherback turtle, Florida panther, and West Indian manatee. As there is no public transportation to the park, renting a car or joining an organized boat or bus tour is the best way to get to this wildlife experience.
