Bocca d’Osa is the narrow lagoon mouth near Orbetello where the Argentario sea meets the Orbetello lagoon — great for birds, reflective water patterns, and dramatic sunsets. Best at sunrise or golden-hour sunset for warm side lighting and long reflections; migratory seasons (spring/autumn) bring raptors and waders. Easily reached by car from Orbetello with roadside parking; area is a protected wetland—respect trails and signage. No gate fee, but expect wind off the Tyrrhenian; bring windproofs.
