Wreck Reef appears to snow rather heavily. It is a rather coastal island, with numerous sea stacks and formations surrounding the island and several hills and cliffs on the island itself. It also features a crystal clear lagoon with abundant crabs in it. Apart from several pine trees dotting the surface, the area is rather sparse in terms of vegetation. There is said to be many reefs underneath the water's surface, causing ships to wreck. In the Wild Skies maps, it is shown as a series of jagged cliff edges facing each other with the sea running between them, though the Race to the Edge map simply shows it as a rather small island.
Interestingly, a "Wrecker's Reef" is mentioned in the Book How to Train Your Dragon of the Book series when: "The Green Death's foot completely destroyed Wrecker's Reef with one blow." There is no "Wrecker's Reef" on Berk of the Books, where the Green Death was located at the time. There is a Wrecker's Bay, however, that is located on another island far removed from Berk.
