Steep Holm Visit


Steep Holm ~ Cardiff Departure

The Island of Steep Holm lays within the English side of the Bristol Channel. Roughly 6.5 nautical miles from Cardiff and 5 nautical miles from Weston-Super-Mare.

Purchased in 1976 as a living memorial to Kenneth Alsop, a broadcaster, author, and passionate campaigner for conservation causes, who died in 1973, Steep Holm is a nature reserve, bird sanctuary, and Site of Special Scientific Interest due to its rare plants, including the May flowering wild Mediterranean Peony. Here you can find peace and quiet (when the gulls have finished rearing their young) with fantastic 360 degree views of the Bristol Channel and the Somerset and Welsh coastlines. Walk the cliff tops, ramble around the military buildings, explore the underground ammunition stores, get involved with an archaeological dig, or simply while away the day on a rugged and beautiful island.

Due to the nature of the tides within the Bristol Channel (Second largest tidal range in the world), visits are conducted over two high water periods allowing visitors between 10-12 hours to explore.

The trip will start with a departure from Penarth Marina, a journey time of around 20 minutes will see you arrive at the shingle beach. From here the Island guides will explain the day ahead and keep you informed of your pick up time.



You can be guaranteed beautiful views, peace, tranquillity and a day away from the hustle and bustle of normal life. Tea, coffee and often cakes are available to purchase, but it is also advisable to take your own food for the day.  The island also has a licensed bar and there are modern toilet facilities nearby, as well an indoor place to rest. Be sure to take a camera and capture some shots to remind you of your day.


The price of the ticket includes your return journey to the Island on one of our vessels, lifejackets and the landing fee (that helps to keep the Kenneth Alsop Trust going and preserving this amazing place).

Further information on items to take with you, location of pick up points and other useful topics will be sent through with your booking confirmation.

Should you have any further questions prior to booking feel free to drop us an email or give us a call.

You can also visit the Islands website which contains various information ahead of your visit.

Pricing / Information

All tickets £45 (As these trips are run on behalf of the Kenneth Alsop trust we are unable to offer any concessionary rates on tickets.)

Duration: Approx 12hrs on the island

Island Suitability: Access and Egress to the Island is via the side of the boat onto a shingle beach. Once on the Island there is an incline to overcome before reaching the top and the barracks. The tracks and paths around the island can be rugged, for this reason we do not recommend the trip for those with walking difficulties.  

Age suitabilityThe boat trip is suitable for those 1.1m tall and over who must be able to hold on for the duration of the trip by themselves in their own seat. It is not suitable for young children who cannot sit, brace and hold on by themselves. The journey across to Steep Holm does take time and sea conditions are variable, so please consider this.

Trip times: Please arrive on time for your departure and to allow for your safety kit, and briefing.  We are unable to wait for any late comers due to tide and lock restrictions, which can impact landing on the island.  Your return time will be approximately 12 hours after your departure time depending on the tides.

Departure: Cardiff Departure is from our container in Penarth Marina (NOT Mermaid Quay).

Cancellation note:  Due to the changes in weather, on occasion we may have to cancel the trip for safety reasons.  If this occurs we will aim to provide 48hrs notice.
