Vík’s most iconic cluster of sea stacks is known as Reynisdrangur, which rises from the ocean like ebony towers at the western end of Vík's black-sand beach. Tradition says they're masts of a ship that trolls were stealing when they got caught in the sun. The nearby cliffs are good for puffin watching. A bracing walk up from Vík's western end takes you to the top of Reynisfjall ridge (340m), which offers superb views.
