Our journey to Flat Holm began at Cardiff Bay, where the Lewis Alexander, a boat built to carry 45 passengers, awaited us. As we set sail, we faced short, steep waves that towered like 10-foot brick walls and massive currents generated by the second highest tidefall in the world. The captain of the Lewis Alexander warned us about the whirlpool that could spin our boat around, adding a sense of excitement to our adventure.

A Rich History and Home to Seagulls

Flat Holm, or Ynys Echni in Welsh, has a long history dating back to the Bronze Age. Over the centuries, the island has served as a refuge for Vikings, a home for religious hermits, and even the founding site of the Bristol Channel Mission, which later became the Mission to Seafarers. Today, Flat Holm is a Local Nature Reserve managed by the Cardiff Council as The Flat Holm Project, supported by the Flat Holm Society.

The island is also home to a large population of seagulls, including lesser black-backed and herring gulls. Visitors during the nesting season should be prepared for these protective parents to screech, yell, and even dive at intruders who venture too close to their nests.

As we circumnavigated Flat Holm, we discovered the remains of its human history, including the 90-foot lighthouse and the giant foghorn built in 1906. The island's isolation hospital, now in ruins, served as a testament to the island's role in treating sailors suffering from infectious diseases during the 19th century.
