Flat Holm Island Outdoors

Just 5 miles from Cardiff and Barry, the tiny island of Flat Holm is a different world with a wealth of history and wildlife. You will be amazed at how much there is to discover.

Since the Dark Ages, Flat Holm has been a retreat for monks and since then has acted as a sanctuary for Vikings, Anglo-Saxons, silver miners, smugglers and cholera victims. Fortified in Victorian times and again in World War II it is perhaps most famous for receiving the first ever radio message across water by Marconi in 1897.

A short day visit to Flat Holm will give you 3 hours on the island, where visitors can purchase a self guided tour pack, providing a unique opportunity to discover Flat Holm's wildlife and historic buildings. Guided tours will be available on certain dates. There will be a chance to relax and enjoy the island's atmosphere with a cup of tea or coffee and a chance to visit our well stocked souvenir shop selling monoculars and caps, fairtrade snacks and drinks and a range of souvenirs for you to buy as a memento of your island experience.
