Boat Trips, Sea Safaris & River Cruises in Cornwall

From puffin-spotting off Padstow to dolphin pods off Falmouth and seal colonies at St Ives, Cornwall's harbours are the starting point for some of the best wildlife watching in the UK - plus heritage river cruises, scenic ferry crossings, and a National Marine Park sea safari just over the border in Plymouth.

Back to Activities

Cornwall's coastline is one of the richest stretches of water in the UK for spotting marine wildlife, and sea safari operators run from almost every harbour of any size. In North Cornwall, Padstow Sealife Safaris has over 30 years' experience exploring the Camel Estuary and out to "Puffin Island", while the Jubilee Queen offers a gentler, 40-year-old alternative with a licensed bar on board. Over in West Cornwall, St Ives Boats runs the famous Dolly P out to Seal Island and Godrevy Lighthouse, while Coast Boat Trips in Hayle explores the dramatic north coast with guides holding zoology or marine biology degrees. Over in Penzance, Marine Discovery Penzance has run wildlife watching trips under sail aboard the catamaran Shearwater II since 2005, with qualified marine biologists on every crew.

Falmouth has two well-established operators of its own: Orca Sea Safaris has been searching for dolphins, whales and basking sharks since 2006, while AK Wildlife Cruises runs longer, WiSe Master-accredited trips of up to eight hours with naturalist guides collecting ongoing research data on every voyage.

South Cornwall has its own cluster of operators too: Mevagissey Sea Safaris and Looe Sea Safari both run RIB trips exploring hidden coves, offshore islands and the Eddystone Lighthouse, while Looe's Original Glass Bottom Boats gives a gentler alternative, cruising around Looe Island's seal colony with glass hull panels for views of the sea life below. Over in Penzance, Mermaid Pleasure Trips heads out to St Michael's Mount or along to Porthcurno and the Minack Theatre. And if you're staying in or travelling via Plymouth, Plymouth Marine Safari runs wildlife safaris into the UK's first National Marine Park in Plymouth Sound.

Prefer something a little more sedate? Cornwall's rivers and harbours also have a strong heritage boat trip tradition. Fowey River & Sea Cruises and Enterprise Boats' Fal River Cruises both offer guided, scenic trips steeped in local history, while public ferries such as the St Mawes Ferry and the Mevagissey to Fowey Ferry are a practical way to get between two harbours - with a good chance of a seal or dolphin sighting along the way. From Plymouth, the historic Cremyll Ferry is one of the quickest ways to step from Devon into Cornwall, landing at Mount Edgcumbe in minutes, while Plymouth Boat Trips' Calstock Cruise sails right up the Tamar Valley to the Cornish village of Calstock, with a stop at the National Trust's Cotehele Quay on tide-dependent sailings.

Prefer to take the helm yourself? See our separate guide to Boat Hire, Kayak & Canoe Hire in Cornwall for self-drive motorboats, kayaks, canoes and SUPs to hire by the hour, day or week.

Good to know before you book

  • Wildlife isn't guaranteed: these are wild animals in their natural habitat, not an aquarium - most operators are honest that sightings can't be promised, however experienced the crew.
  • Check age and health restrictions: fast RIB-based trips commonly exclude pregnant women, children under 2, and anyone with current or historic back, neck or bone problems - confirm before booking.
  • Dress warm, even in summer: it gets cold and wet out on the water, especially on open RIBs and sunset trips - bring layers, a windproof coat and secure closed-toe shoes.
  • Weather-dependent: trips can be postponed or cancelled at short notice for sea conditions - build some flexibility into your plans, especially if booking for a specific day of a short break.
  • Sea sickness: if you're prone to it, take suitable tablets in advance of boarding, in line with the packet instructions or pharmacist advice.

Frequently Asked Questions

Sea safari operators run from harbours right around the Cornish coast, including Padstow Sealife Safaris and the Jubilee Queen in North Cornwall, St Ives Boats and Coast Boat Trips in West Cornwall, Marine Discovery Penzance and Mermaid Pleasure Trips in Penzance, Orca Sea Safaris and AK Wildlife Cruises in Falmouth, and Mevagissey Sea Safaris, Looe Sea Safari and Looe's Original Glass Bottom Boats in South Cornwall.

Common sightings include grey seals, dolphins, porpoises and a wide range of seabirds, with basking sharks, sunfish, minke and fin whales and bluefin tuna turning up seasonally at some locations, and puffins visible on North Cornwall trips between April and July. Sightings are never guaranteed, as these are wild animals in their natural habitat.

Yes, these vary by operator and boat type. Fast RIB-based safaris often exclude pregnant women, children under 2, and anyone with current or historic back, neck or bone problems, while some longer trips have higher minimum ages. Always check the specific requirements with the operator before booking.

Yes. Plymouth Marine Safari runs half-day, all-day and sunset wildlife safaris from the Barbican in Plymouth Sound and the UK's first National Marine Park, looking for dolphins, seals and seabirds, plus dedicated blue shark snorkel trips further offshore. It's in Devon rather than Cornwall.

Yes. Fowey River & Sea Cruises and Enterprise Boats' Fal River Cruises both offer scenic, guided heritage cruises rather than dedicated wildlife trips, while public ferries such as the St Mawes Ferry, the Mevagissey to Fowey Ferry and the historic Cremyll Ferry cross waters where seals and dolphins are regularly spotted. Plymouth Boat Trips also runs a heritage cruise up the Tamar Valley from Plymouth to the Cornish village of Calstock. Sightings are a bonus rather than the main purpose of these trips.

Prices, timetables, age and health restrictions and booking requirements are set by individual operators and may change without notice, and wildlife sightings can never be guaranteed. Several of the heritage cruises and ferries on this page run seasonally and are weather and tide dependent, so please check current sailing times directly with each operator before travelling.
