Baia dos Tigres is the great coastal feature on Iona's Atlantic side, an extensive bay and sand-spit landscape that feels closer in spirit to Namibia's Skeleton Coast than to tropical Angola. It is remote, wind-scoured, and unforgettable when conditions are clear.
The area is important for marine and bird life, including Cape fur seals and seabirds, but it is not a casual beach outing. Access depends on route conditions, tides, and local permission. Go with people who know the coast.
