How do I get to Flat Holm Island?

Head down to the Celtic Ring in Cardiff Bay, where you'll spot Bay Island Voyage's blue RIB boats.

Flat Holm Island has a history dating back to as early as the 6th century, acting as a harbour for Saxons, Vikings, monks and even smugglers – some of its history is a paper Morse slips transmitting the first ever radio message across the water that made the island famous, is now in the National Museum of Wales. Its isolation means that wildlife thrives, being host to large numbers of seabird colonies and maritime grassland that breeds rare flora.

You can take trips to the island all year round. You can take a pre-organised day trip from Cardiff bay, usually lasting from 3 to 6 hours – you’ll admire the island’s fantastic views of the Welsh and English channels and tranquil atmosphere, and explore the beauty of its wildlands and artefacts. You can take a guided tour around the island, or if you just fancy a peaceful walk by yourself, you can purchase one of the self-guided tour packs. Finish off your visit to the island by taking something home from the gift shop to commemorate your visit, by choosing from a range of Fairtrade items and gifts.
