On the Tour

Once you arrive on the island our friendly crew will meet you and take you straight to the boat for your first day at sea where we will head to the lagoon. This is the perfect place for beginners to test the waters, and those with more experience to take advantage of the abundant life and crystal-clear visibility.

Each day will focus on searching for wildlife and snorkelling. The deep waters around the island create excellent feeding opportunities for sharks, whales and dolphins. Photographers and naturalists will keep themselves busy with the plentiful bird life.

Our fantastic itinerary includes many other highlights of the Hebrides, it’s flexible in nature to allow for the wild Atlantic conditions. Here is a flavour of what to expect.

Swimming with Basking Sharks

The Sea of the Hebrides is the only Marine Protected Area (MPA) for basking sharks in the world. Swimming alongside these gentle giants is a moment you will never forget. Visit these endangered animals responsibly, with our dedicated and passionate team.

Over the past decade, we have developed our Code of Conduct for encountering sharks to ensure their welfare & protection. This practice ensures both shark and customer safety which is our highest priority and allows you to get the best chance of a memorable experience.

Basking sharks migrate to the Hebrides every summer to feed and potentially breed. You can find more about them here, along with reading what it takes to find and swim with them here.

Swimming with Seals

Scotland boasts one third of the world’s grey seal population, swimming with these curious animals is a moment you will remember. We have multiple options around the islands where we have resident seal colonies to visit – as well as the cute common seals that can even be spotted from the harbour!

Hebrides Lagoon Swim

A favourite of many visitor. The white shell sand lagoon has fantastic visibility and sheltered conditions. The currents squeeze through the many channels creating lush kelp forest & algae gardens. Making it a haven for lots of marine life and seals.

Whales, Dolphins & Atlantic Wildlife

Humpback in the Hebrides, Isle of Coll

The Hebrides are known as a worldwide hotspot for marine wildlife. Being situated on the edge of the Atlantic means we have fast access to productive feeding grounds. We have both resident and seasonal marine mammals that we can encounter. Along with the large seabird colonies we have the chance of some great encounters. Check out the marine life guide here.

Visit Puffins at the Treshnish Isles

Our favourite characters visit the islands from spring to the end of July. Rest your sea legs on the beautiful Isle of Lunga, an idyllic lunch spot to enjoy a picnic the puffins. This island is a bird watchers paradise with breeding colonies of puffins, guillemots, razorbills, fulmars, kittiwakes and shags.

Explore the kelp forest

Moon jelly in the kelp forest

We offer a snorkel excursion every day of the trip, whether that be at the lagoon, seal colonies, tidal channel drifts, fingal’s cave. Atlantic kelp forests are more productive than coral reefs and there is a vast amount of marine life to discover around them. The guides will help you find lots of critters ranging from the smallest nudibranch to biggest lions man jellyfish.Have a look at our underwater wildlife guide here.


Fingal’s Cave

Swimming fingals cave

Visit the legendary Fingal’s Cave on the Isle of Staffa – the basalt columns formed from volcanic activity fringe the cliffs of the island, plunging in to the water. An adventure playground which will be a highlight for snorkellers, swimmers and watchers alike. Snorkelling in this natural wonder should be on every bucket list!

Alternative Activities

Brechacha Castle on Coll

Located in the Hebrides on the edge of the Atlantic means we can often experience very strong winds. This can mean it’s too rough to be at sea or make boarding dangerous.

In this instance we will arrange  land activities. In addition to shore snorkelling, we can explore the island’s local wildlife, landscapes and history. There are fantastic habitats such as sand dunes and machair to discover. Historic castles, standing stones, pete cutting and local stories of life in the islands. Wildlife such as eagles, hen harriers, otters, hares and corncrakes are all things to keep an eye out for – as well as the iconic highland cattle!

Life on the Island

Isle of Coll beach

In the evenings enjoy the quiet life Coll has to offer, with remote beaches, otter spotting and stunning sunsets.  This idyllic island is home to an award winning restaurant and accommodation providers, but if wild camping is more your style you won’t be short of peaceful spots to enjoy.

Who is the tour for?

For the ocean loving adventurer who wants to maximise their opportunities for shark encounters – the seven day tour is for you. This tour is about the wildlife, however you would like to enjoy it – be it in the water or on board the boat. To join our in water activities you must be comfortably able to swim a minimum of 100m unaided in open water. With the remote location we operate in there are some physical challenges such as boarding the boat by ladder and landing on the islands without facilities, please see here for more information.

Tour expectations

The natural world is very unpredictable, not a zoo or an aquarium, therefore sightings are never guaranteed. We can however promise that you are visiting a wildlife hotspot with a highly experienced and passionate team. Our boats are comfortable cabin RIBs built for the wild Atlantic conditions which are closely monitored by our experienced skippers. We will do our very best to give you a great experience!
