Farol de Alfanzina stands where the Lagoa cliffs run at their sheerest — a working lighthouse on a headland between Carvoeiro and Benagil, with vertical drops to the water and nothing to soften the geometry. By day it is a white waypoint on the Seven Hanging Valleys trail; the reason it earns its own listing is what happens after the day ends.
This is one of the central Algarve’s better night spots. The headland faces open sea to the south, so the dark horizon suits night-sky frames, and the lighthouse beam sweeping overhead adds an element most coastal night shots don’t have. In winter the brief flips: Atlantic storms throw swell against the cliffs below the light, and the lighthouse-above-chaos shot becomes the one to chase.
When to go: clear, moonless nights for stars; big-swell winter days for storm work; and late afternoon any time of year if you just want the walk — the trail sections either side of the lighthouse are some of the best cliff scenery on the route.
The practical picture: the lighthouse is signed off the Carvoeiro–Benagil road and reachable by car, so you are not hiking in to shoot in the dark. The compound itself is a working installation — the shot is from the clifftops around it, not inside the fence. Those clifftops are unfenced in places and genuinely dangerous at night or in wind: learn your edges in daylight, and give storm waves far more margin than feels necessary.
Who it’s for: night photographers who want a subject on their star frames. Storm chasers in winter. Trail walkers who want the landmark. Not for anyone casual about cliff edges — this headland punishes inattention.
