Madeira is a mountain island, but it is also a sea island, and much of its charm shows up when you leave the land. The Atlantic drops away to enormous depths within a few kilometres of the shore, which brings dolphins, whales, turtles and sea birds close to the coast, and the volcanic rocks and bays make a playground for swimmers, paddlers and divers. If your trip is all trails and viewpoints, a day or evening on the water will balance it. This guide lays out the options so you can choose the right boat or activity for your time, budget and stomach.
Whales and dolphins from Funchal
The most popular sea outing is a wildlife trip from Funchal marina. Because deep water lies so close to the coast, several kinds of dolphin are resident or seen regularly, including common and bottlenose dolphins, and whales are spotted in some seasons. Boats range from fast inflatables to large catamarans, with trips of two to three hours. Choose an operator that follows responsible-watching rules, keeps its distance and limits time with the animals. Sightings are never guaranteed, but the chances are good. Morning and late afternoon departures usually have calmer water.
The Desertas Islands
For a full day at sea, a catamaran cruise to the Desertas takes you across open water to three uninhabited islands that form a protected nature reserve, home to sea birds and one of the last colonies of Mediterranean monk seals. Landings are restricted, so you view the cliffs from the boat, swim in a sheltered bay and eat lunch on board. The crossing can be lively, and the day is long, so it suits calm-sea travellers and those who love wildlife. Take a seasickness remedy if you are prone, pack layers and expect to be salty and sunburnt by evening.
Sunset sailing
If you want something gentler, a sunset catamaran cruise leaves the marina in the late afternoon and sails along the south coast, giving a view of Funchal’s amphitheatre and the cliffs with the light turning gold. It is short, usually two to three hours, and suits couples and families alike. Drinks and snacks are often included, but check the details. The evenings are breezy, so bring a jumper.
Snorkelling and kayaking
Madeira is not a coral-reef destination, but the clear water and rocky reefs hold plenty of fish. The Garajau marine reserve, on the coast east of Funchal, is protected, so the fish are abundant and calm. A guided kayak and snorkel trip combines a gentle paddle along the cliffs with a swim over the reef, and is a good choice for beginners. Mornings are calmer, and operators provide gear and briefings. Do not touch the fish or the reef, and use reef-friendly sunscreen.
Coasteering and canyoning
For adrenaline, try coasteering, which combines swimming, scrambling and jumping along the volcanic shoreline with a guide, or canyoning in one of the island’s ravines, abseiling and sliding down waterfalls. Both activities are run by trained guides with full safety kit, and they have minimum age and fitness requirements. They suit confident swimmers and active teenagers and adults. Sea conditions and rain affect both, and good operators will cancel or change plans for safety.
Seasons and conditions
The sea is calmest and warmest from late spring through early autumn, with water temperatures that feel refreshing rather than tropical. Winter brings bigger swells and cooler water, though the coast is still sunny on many days, and boats may be cancelled when the sea is rough. Wind often builds in the afternoon, which is why morning departures are popular. If you are visiting in the colder months, focus on wildlife trips and sunset cruises rather than swimming.
Seasickness and safety tips
The open Atlantic can be bumpy, particularly on the way to the Desertas. Take a remedy before you board rather than after you feel unwell, sit in the middle of the boat, watch the horizon, drink water and avoid heavy meals. Wear a hat, sunglasses with a strap and sunscreen, and bring a windproof layer. Listen to the briefing, wear life jackets when asked, and check the age and swimming requirements for children.
Sample plans
For a relaxed week, add one wildlife trip early in your stay, when you can reschedule if the weather is poor, and a sunset cruise towards the end. For active travellers, pair a coasteering or canyoning morning with a seafood lunch in Câmara de Lobos, and schedule a rest afternoon. For families, a short dolphin trip and a kayak and snorkel morning are a good mix. Keep one flexible day for sea conditions, and remember that the mountains will still be there if the boats do not sail.
