Shark Trips

Shark Trips

Basking Sharks

Adult basking sharks can measure up to 39 feet (12 metres) in length and can weigh up to 7 tonnes. They are the second largest species of shark in the world, after the whale shark. They are harmless plankton feeders and can live up to 50 years.

The main season in Cornwall for these gentle giants is around mid may through to late June. Although they can be seen in the months before and after this. They usually start to appear when the water temperature hits 13 degrees and we get our second plankton cycle. They then follow the plankton bloom up to Scotland and beyond. They can filter around 1000-2000 cubic metres of seawater per hour and can be found in large schools of over 100 sharks. Cornwall is one of the best places to see basking sharks and the water clarity of up to 20 metres gives underwater photographers optimum conditions to take their photographs.

Our basking shark trips can be run in 2 ways. Either divers book the bigger hardboat, the Celtic Cat in advance as a dive trip and if the sharks are around for that date booked, then they can upgrade to a shark trip. Or we can add people to the basking shark mailing list and when we know that the sharks are around in decent numbers, we email everyone. This then gives people a window of about a month to book a trip. Importantly, these trips are strictly snorkelling trips. We follow a strict code of conduct set out by WiSe. We do not take people out unless we feel that the conditions are right and sightings have regularly occurred and that we feel that there is at least a 75% chance of seeing the sharks. The trips cost £60pp and includes a light lunch.

Blue Sharks

The blue shark is an open-ocean pelagic species. It visits the UK seas in summer months between June and September. They are active predators and feed mainly on small fish like anchovies and squid, but also mackeral, seals and even birds. They have been recorded at depths of up to 350m. The largest blue shark ever caught in UK seas weighed a whopping 256lbs (116kg) and measured over 9ft (2.74m). They are normally seen over 10 miles off shore.

Like the basking shark trips, we can organise the trips in one of 2 ways: Either divers book the bigger hardboat, the Celtic Cat in advance as a dive trip and if the sharks are around for that date booked, then they can upgrade to a shark trip. Or we can add people to the blue shark mailing list and when we know that the sharks are around in decent numbers and conditions are right, we email everyone. This is usually for more last minute trips.

Importantly, these trips are strictly snorkelling trips. We follow a strict code of conduct set out by WiSe. We do not take people out unless we feel that the conditions are right and sightings have regularly occurred and that we feel that there is at least a 75% chance of seeing the sharks. The trips usually last about 6 hours, usually going 15 – 20 miles off shore. These trips cost £100 per person and they include a light lunch.
