The eruption lasted for several months, leading to the evacuation of the island's residents and the destruction of many homes. Today, Eldfell is a popular hiking destination, offering stunning views of the surrounding area. The volcanic activity has created unique geological features, and visitors can learn about the island's history and the impact of the eruption at the Eldheimar Museum.
