About Bay Island Voyages
Bay Island Voyages is a Cardiff-based boat operator offering coastal trips and island visits from Cardiff Bay and Weston Super-Mare. The company runs short bay voyages, one-hour coastal trips, children's birthday party charters, and island visits to Flat Holm and Steep Holm. Trips vary in duration from short fifteen-minute bay rides up to two to three hour island visits, with specific thirty- and sixty-minute party options available.
From Cardiff Bay departures, experiences include the fifteen-minute Bay Voyage around Cardiff Bay, the one-hour Coastal Voyage that explores the Welsh coastline and Flat Holm Island, and organised Steep Holm visits that showcase the island's wildlife and historic military structures. The sixty- and thirty-minute children's birthday party trips travel through the Cardiff Barrage lock system and provide tailored group experiences suitable for children meeting the stated height requirement for the thirty-minute run (over one point one metres).
Flat Holm visits are two to three hour excursions focusing on island history, the Trinity House Lighthouse, birdlife, and military relics. Steep Holm trips, offered from both Cardiff Bay and Weston Super-Mare, highlight panoramic views, nature reserve features, archaeological interest, and rare plants and bird species.
Bay Island Voyages operates with a small-group focus; the Bay Voyage is limited to a maximum of twelve passengers, creating an intimate experience. Trips provide opportunities for wildlife spotting such as seals and for photography at Wales' southernmost point. Timings, meeting points, and booking details are provided by the operator at time of reservation. Schedules change with local tide patterns.
