FLAT HOLM ISLAND VISIT
Flat Holm Island – the jewel in the Bristol Channel.
Flat Holm is a nature reserve managed by Cardiff Council. Positioned at the most Southerly point in Wales, 4.5 nautical miles from Cardiff.
The island is steeped in history and rich in wildlife with plenty to see and do. From the military remains with canons and gunning placements to the several species of wild birds, wild garlic and the unmistakeable Trinity House Lighthouse; there is something for everyone to see and do. Explore the displays highlighting Marconi’s first wireless transmission over water in 1897, how the island housed a cholera and isolation hospital and the part in played in World War II.
Departing from Mermaid Quay in Cardiff Bay, you will head towards Cardiff Bay Barrage and lock out into the Bristol Channel. Depending on the tides and weather, you will get an average of 2– 3 hours on the island for your visit. The Island Warden and volunteers will meet you upon arrival and are on hand to offer a guided tour of the island.
Flat Holm has a small shop and Wales’ most southerly pub – The Gull and Leek. There is plenty of space to relax and enjoy a picnic outside and you can purchase drinks from the pub and gifts from the shop – please note both of these are cash only.
For the more adventurous you can even stay overnight in a range of the accommodation on offer or camp under the stars! (Arrange accommodation directly with Cardiff Harbour Authority then transport with us)
At Bay Island Voyages we have the knowledge and safety in place to ensure you have a great visit. Even after many years and many visits, we always find something new and exciting! No two visits are the same due to the changing seasons and wildlife on the Island. We run trips to the Island between March – October.
*As the island does not have its own waste disposal, they kindly ask that all visitors take their rubbish off the island with them.*
On selected dates there will be a member of the Flat Holm Society to offer a guided tour of the island (Free of Charge).
