Colombia
A beautiful Caribbean island a short plane ride from San Andres. Very undeveloped and with some beautiful, empty palm fringed sandy beaches - picture postcard stuff. There's only a handful of small little hotels on the island - it's all low key tourism in Providencia.
Top tip - take a boat trip around the island and visit the beautiful Crab Caye, a great place for snorkelling or admiring the amazing shades of light blue.
