Skansinn, also known as Kornhólsskans, is a historical site in Vestmannaeyjar that offers a leisurely hike with a bit of history thrown in. Built in 1586 to defend against potential invasions, Skansinn features a cannon from the same era and a replica stave church. You can also explore Landlyst, the first maternity home in Iceland, now housing a medical museum. Don't miss the 1931 maritime tank half-buried in lava from the 1973 eruption. Plus, there's a picnic-perfect valley nearby called Hraunskógur, once dubbed Death Valley for its toxic gas but now safe to visit. It's a cool spot for a chill day out!
