📋 Practical info
Best season
The best time to observe dolphins in the Sado Estuary is from April to October, when sightings are most frequent. In spring and summer the water is calmer and visibility is better.
Best time of day
Early morning boat trips offer the best chance to see dolphins, as the animals often hunt closer to the surface then. Late afternoon tours are also popular when the sun is lower.
Etiquette
Keep a distance of at least 50 metres from the dolphins during the boat trip to avoid disturbing them. Do not feed or touch the animals; this can permanently impair their natural behaviour.
What to bring
Binoculars are very helpful to spot dolphins in the distance. A waterproof camera or phone with good zoom is recommended to capture the moments.
Getting there
The Sado Estuary is located near the city of Setúbal, about 50 km south of Lisbon. Most dolphin-watching tours depart from the port of Setúbal or the Tróia peninsula.
What to expect
Dolphins are wild animals - there is no guarantee of seeing them, though chances are high in this area. Plan at least two hours for the boat trip and enjoy the scenery.
