Part of the Netherlands since the 17th century, Curacao’s Dutch colonial architecture makes it feel like a European city transposed to the edge of the Caribbean. This tiny island found off the north coast of Venezuela is ringed by almost 40 beaches. Head to Seaquarium Beach, also known as Mambo Beach, for excellent swimming and easy access to bars and restaurants. Then, make your way south to Daaibooi, which is known for its top-notch snorkelling. Curacao is generally bypassed by hurricanes and all-day rains, making June a great time to visit to take advantage of low, off-season rates.
