For a small limestone island (approximately 620 metres in diameter, covering 86 acres) it does have a lot of interesting features and areas. As you will see from the map below, we have several nature reserves as well as a gull colony. There is a water tank to provide running water to the buildings and solar panels to provide electricity (the island has its own mini grid). There is a solar panel powered lighthouse, a barracks, a foghorn station, keepers house and farmhouse. The blue lines map out a defined track around the island. There are two jetty and north facing beach. It is a real gem in the Bristol channel.
