THE ADVENTURE COLLECTIVE® · Independent discovery and booking for outdoor travel

Read the full experience

The catamaran slips off the stone edge of Doca de Belém and the Tagus opens like a broad, briny road. Wind tugs at your hair, the deck hums with conversation and the city’s monuments slide astern: the angular figures of the Discoveries Monument, then the squat silhouette of Belém Tower guarding the mouth of the river.
