It's a truly wonderful experience when the lock is opened for the sailing ships. This exciting spectacle, as the road is closed, the drawbridge is raised, and the sailors enter and exit the lock, is not to be missed.

Built in 1882, the Pen Lan Lighthouse is 18 meters tall and has a light range of 15 miles (24 kilometers). Out of use since 1995, its last guardian was a female guardian. It now remains in memory of the sailors who once guided themselves by its light.
