7-night Vida Portugal: Vineyards & Villages Along The Douro Cruise From Porto (Oporto), Portugal

Avalon Waterways

A large concrete dam near Pocinho, Portugal, spanning a calm reservoir in a rugged, semi‑arid landscape. Rocky hills with sparse vegetation rise around the structure, and spillway gates line the front of the dam. Clear blue skies highlight the contrast between the engineered waterway and the natural terrain.
