Mutton Island is home to two things, and neither is related to sheep. The first is a privately owned sewage treatment plant that serves the mainland. The second, and arguably more interesting, is a lighthouse and attached keeper's quarters built in 1817.
A causeway measuring approximately 850 meters (just a little over half a mile) connects the island to the Galway mainland. This causeway is accessible to the public, and the expansive views of Galway Bay along it are incredible. It might be a good idea to bring a jacket when visiting, as it can get windy and chilly out there.
At the end of the causeway, a locked gate and a sign state that the island is off limits, and that those wishing to see the lighthouse must make an appointment with the City Council Heritage Officer. Whether this works is unclear, but it's certainly a no-go for non-resident visitors who are not staying long.
On its bicentennial anniversary, it's a shame that the lighthouse is still inaccessible to the general public. The official website states that the lighthouse is undergoing restoration. Future plans have not been made known. read more
