Join us on a long-range whale watch expedition for a fantastic encounter with one of the most iconic of all the great whales. We run our  Blue whale expeditions from June to August at the peak of the Blue Whale Season.

It’s always a great idea to bring warm clothing, a sweater and a rain jacket (Layering works wonders) We'll also be under the sun so please bring biodegradable sunscreen, sunglasses and a hat.
