Ilha Deserta

Ilha Deserta—literally 'Desert Island'—is one of the Algarve's most extraordinary beach experiences: a 7-kilometer stretch of pristine white sand on a completely uninhabited barrier island. Located at Portugal's southernmost point (Cabo de Santa Maria), this is as close to a true desert island experience as you'll find in Europe. The island lies within the Ria Formosa Natural Park and has been uninhabited since 1987. There are no roads, no houses, and no permanent residents—just endless sand, crystal-clear water, and the single restaurant O Estaminé near the ferry landing. The restaurant runs entirely on solar power and serves fresh seafood with views over the Atlantic. What makes Ilha Deserta special is its raw, unspoiled nature. Over 300 bird species have been recorded in the Ria Formosa, and the island is a hotspot for birdwatching. A 2km boardwalk called the Santa Maria Trail leads through the dunes, showcasing the island's unique flora and fauna. For the adventurous, walking the entire island perimeter takes 8-9 hours. The western section of the island is an official naturist beach, accessible via a 30-minute walk from the ferry. Even in peak summer, you can find stretches of sand where you're completely alone. The water here is exceptionally clean—so clear you can see shells on the sandy bottom—and can reach 24°C in summer. Just remember: if you miss the last ferry (around 6pm), you'll be stranded until morning.
