Based at Gairloch's harbour, this set-up runs three trips: a standard 2½-hour whale-watching excursion (from May), a three-hour visit to the seabird-rich Shiant Islands and a four-hour excursion to further-flung feeding grounds in search of orca. Other wildlife it's possible to see includes otters, dolphins and seals. Trips are in a zippy rigid inflatable.
