Flowing gracefully through the heart of Aveiro, a picturesque city on Portugal’s central coast, the Aveiro Channels (Canais de Aveiro) are the lifeblood of this charming destination often nicknamed the “Venice of Portugal.” With colorful moliceiro boats gliding along tranquil waters, elegant bridges, and pastel-toned buildings reflected in the canals, Aveiro offers visitors a blend of romantic beauty, maritime history, and authentic Portuguese charm.
The canals are part of the Ria de Aveiro, a vast lagoon that connects the city to the Atlantic Ocean and has shaped its identity for centuries—first as a fishing and salt-harvesting hub, now as one of Portugal’s most enchanting tourist destinations.

Aveiro’s canal network dates back to the Middle Ages, when the city thrived on salt production and maritime trade. The lagoon, known as Ria de Aveiro, was both a natural defense and a transportation route for goods and salt.
The moliceiros, the traditional long, narrow boats with colorful, hand-painted prows, were originally used to harvest moliço—seaweed used as fertilizer for local farmland. Over time, as agriculture modernized, the boats found a new purpose: carrying visitors through the canals, preserving the city’s nautical traditions while showcasing its beauty.
Today, the Aveiro channels are both a symbol of the city’s heritage and a gateway to discovery, connecting travelers to its culture, architecture, and cuisine.
