Looking for things to do in Cardiff? Look no further…

Bay Island Voyages offer a great range of fun days out! From a blast around Cardiff Bay to a scenic tour of Flat Holm Island, we have it covered.

Bay Blasts

For our adrenaline junkies Bay Island Voyages are Cardiff’s Ultimate Boat ride! We offer an unforgettable RIB experience with our 15minute ‘Bay Blast’.

Bay Blasts are the original and signature trip we have to offer. We take a short trip to reach the edge of the speed limit before the full power of these vessels is unleashed.

Experience a full tour of the Bay perimeter at high speed, where you will encounter high-speed turns and the vessel will bank and swerve showing the true capability of what RIB boats can do.

We can’t guarantee you won’t get wet but we can guarantee you will have fun!

This is 15 minutes of high-speed excitement and adrenaline fuelled fun for all. It’s the perfect taster for those new to boating. Once you have experienced our Bay Blast, you will be left wanting more!

ALL £9.00

(Please arrive 10mins prior to departure time)

Coastal Trip (1.5hrs)

This is our all-new trip. It’s the upgrade from our original 1-hour trip. There is so much to see and experience in the Bristol Channel, we felt we had to give you the time required to enjoy it.

Setting off from Cardiff Bay we take you through the locking system at Cardiff Barrage. Depending on the state of the tide we either rise or fall to meet the sea level outside. From here we will blast out to Flat Holm Island. The Island is the most southerly point in Wales, rich in wildlife and steeped in history – there’s plenty to take in.

From Flat Holm it’s a brief run across the Welsh / English boarder and on to Steep Holm. Much like Flat Holm but without the amount of wildlife and steeper of course! We will show you the rugged cliffs and remote gunning positions as we take in a full lap of the Island.

On the return trip from the Islands we take in the sights of Penarth and the Pier before heading back through the locks. We aim to finish all of our trips with the customary thrills and spills of high-speed turns and excitement before returning you safely to Mermaid Quay.

With Bay Islands Coastal Trip, you get twice as long at sea and experience more compared to a 1hour trip. This really is the tour to experience everything Cardiff’s coast has to offer.

ADULTS (16yrs+) £30

CHILDREN (15yrs & under) £22.50

FAMILY (2A/2C) £100


For those wishing to explore further try one of our speciality Flat Holm trips where we land you ashore to explore at your own pace.

Flat Holm 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, soay sheep and the unmistakeable Trinity House Lighthouse there is something for everyone to see and do.

Departing from Cardiff Bay we will whisk you out ready for your adventure. Depending on the tides and weather you will get an average of 2 – 2.5 hours for your visit. On the return you will have the chance to see the Island from the water before heading back to Cardiff. The Island has a small shop, Bar and plenty of space to relax and enjoy a picnic. For the more adventurous you can even stay overnight. Please drop us an email for more information and costings.

Having previously run the Councils own vessel “Lewis Alexander” for many years we have the knowledge and safety in place to ensure you have a great visit. Even after many years and many visits I always find something new and exciting to learn about. No two visits are the same due to the changing seasons and wildlife on the Island.

ADULTS (16yrs+) £34

CHILDREN (15yrs & under) £22

FAMILY (2A/2C) £105

Stag/Hen Parties

We have plenty of experience in running both Stag and Hen Trips. Understanding the thrill level required will help us to tailor your voyage. With our location in the heart of Cardiff Bay and central to the restaurants and bars, it’s the ideal place to start your Stag and Hen adventure.

If you’re planning a big night out, then why not jump on-board the following morning, where the fresh air is forced at you, gets the blood flowing again and clears the head of the antics from the night before!

With the ability to carry 12 people per boat we can easily cater for even the larger groups. We will take you out of Cardiff Bay and show you the delights of the Bristol Channel. High octane, adrenaline fuelled fun for all.

Thinking of heading to Central Cardiff following your trip? Why not let us drop you off directly in the heart of the city saving the extra taxi or bus.
