SeaEO-Tours is a Lisbon-based marine tour operator offering speedboat, RIB and wildlife experiences on the Tagus River and nearby Atlantic waters. The company runs guided sunset cruises, dolphin-watching safaris, seabird and marine wildlife excursions, and private RIB charters tailored for groups and special occasions. Tours visit iconic Lisbon landmarks such as the Tower of Belém, the Discoveries Monument, and views of the 25th of April Bridge, and some itineraries travel from the Tagus estuary out toward the Bugio Lighthouse.
Experienced crew members provide live commentary and regional context on each trip. Several tours are led by a marine biologist; the seabird experience includes guidance from an ornithologist. The Birdwatching Tour explores the Tagus Estuary Natural Reserve and operates during migration months from September to May. Dolphin Watching tours are conducted on fast RIBs and include a marine biologist guide during the approximately three-hour ocean safari.
Private RIB charters accommodate groups up to 12 passengers and include certified crew, multilingual guidance, and required safety equipment. Many excursions conclude with a tasting of regional sweet wine as guests enjoy sunset views and photo opportunities. SeaEO-Tours emphasizes responsible wildlife observation and local knowledge, combining marine science expertise with accessible coastal adventures for visitors seeking nature, sightseeing, and private events in and around Lisbon.
Booking options typically list durations, group sizes and safety measures; guests receive pre-trip information and can select private or shared departures to match schedules and preferences. Many departures operate from central Lisbon piers near the city waterfront and local ports.
