From Penzance’s historic harbour you board a three-hour boat tour that threads Mounts Bay: threading past the Islet of St Clements and Mousehole, searching over the shoals for dolphins and porpoise, running out to Longships lighthouse and Land’s End, and returning beneath high cliffs to bays like Mill Bay and Lamorna as you watch for seals, seabirds and seasonal larger visitors.

Highlights

Outing Highlights

THE WILDLIFE

Dolphins, Porpoise and Seasonal Giants

Mounts Bay is a productive feeding ground: harbour porpoises and several dolphin species are often encountered and will sometimes bow-ride; basking sharks are frequently seen and minke whales can appear later in the season.

THE LANDMARKS

Longships Lighthouse and the Land’s End Coast

The route takes you out to the active Longships Lighthouse off Land’s End and along the cliffs where wrecks and dramatic coastal features tell the maritime history of the headland.

THE SEASCAPE

Seals, Seabirds and the Minack Theatre Outlook

Expect to see grey seals hauled out around the Islet of St Clements and an array of seabirds; the trip also passes Porthcurno and the Minack Theatre, providing a cinematic cliffside perspective on the shore.

What the day feels like

What the Three Hours Feels Like

The trip begins with a short run from Penzance across Mounts Bay to St Clements and Mousehole, then pushes south into the bay over a rising seabed that concentrates food and wildlife. The boat works the outer shoals and reefs in search of dolphins and porpoise, moves out to the Longships area and under the cliffs at Land’s End to view wreck sites, then returns along high cliffs and secluded bays — a steady sequence of wildlife searching punctuated by landmark viewing.
