Set on the five-sided island of Faial, Horta is decorated with a colourful cacophony of artworks, which have been daubed across its concrete marina by visitors from around the globe. Left behind by sailors, they tell thrilling stories of life on the high seas. Sitting in the midst of the vast Atlantic, 1,100 miles away from the Portuguese mainland, Horta is the ideal pit-stop for yachts traversing the Atlantic, and one of the world's most visited marinas. The tapered, imposing peak of the Pico volcano, on neighbouring Pico Island, provides a glorious backdrop to the jostling yacht masts of the marina. For the ultimate view, however, you'll need to head up to Faial's own volcanic treasure - Caldeira. Look out from this colossal crater, to absorb the extraordinary views, and a demonstration of a volcano's ability to create as well as destroy. The crater is a natural reserve that blooms with wildflowers and lush green scenery, and scattered sky-blue hydrangeas. Flowers spread colour right across these islands - and you can learn more about the native species at the Faial Botanical Garden.
