The islands on the horizon
From Funchal you can see them on a clear day: a low grey ridge to the south-east that nobody lives on. The Desertas are an IFCN-managed nature reserve and the refuge of the Mediterranean monk seal, trips carry a €3 Natural Park eco-tax, and the boats sail on limited weekly schedules. Only two or three businesses run the trip at all, which makes this one of the few things on the island where the constraint is supply rather than choice.
Boats leave from Marina do Funchal and the Praça do Povo quay at Cais 8.
What the day actually involves
It is a full day: roughly 8.5 to 9 hours round trip depending on the boat. The best-documented sailing takes about 8.5 hours with lunch and the eco-tax included, carries a maximum of 16 guests, and prices at €100 per adult and €50 per child aged 5 to 10 with under-fours free. A second boat runs a comparable day of around 9 hours on a fixed two-days-a-week schedule, though its details come from search listings rather than a page we could read directly — so we verify the timetable before you plan around it.
Crossing open water for that long is the point and the price. You are out beyond the coastal traffic, in the water where cetaceans are genuinely resident: more than 25 species have been recorded off this island across the year. If cetaceans are seen, the boat works to the same code of conduct as every other — minimum distance, speed limits, time limits and radio coordination, overseen by IFCN.
Prices and who it suits
Around €100 per adult is a lot next to a €40 to €67 coastal whale trip, and the difference is honest: it buys a full day, a long crossing, lunch and a place very few people go. Children from about five are accepted, with ages five to ten at half price and under-fours free. Capacity is small — the sailing boat tops out at 16 adults — so groups should ask early.
Weather, and why you should book this early in your week
This is the trip Atlantic swell cancels first. The island itself works year-round, and the south coast is the sheltered side, but a nine-hour crossing needs a settled sea rather than a merely acceptable one. Book it for early in your stay, not the day before you fly. Free cancellation up to about 24 hours ahead is the local norm, and a weather call from the skipper resolves as a reschedule or a refund on the boat’s terms.
Who runs the boat
Licensed local businesses: Portuguese tourist-activity companies hold an RNAAT registration and display it, and Madeira enforces it. We arrange the booking, confirm the sailing date directly and stay reachable; the skipper decides whether the crossing happens.
Nearby: a whale- and dolphin-watching charter if a full day is too much, or a catamaran day out of Funchal. Everything on the island sits on the Madeira destination page, and boats elsewhere on the boat charters page.
Request availability with your dates and the ages of anyone under twelve — we come back with the actual sailing days in your window, and nothing is booked until you confirm.
