Coastal Caves and Sinkholes

The Algarve coastline near Benagil is defined by its karst topography, where millennia of erosion have carved intricate sea caves and vertical sinkholes, known locally as "algars," into the golden limestone cliffs. This selection features the iconic Gruta de Benagil with its natural skylight and sandy beach, alongside numerous lesser-known fissures and hollows. These geological formations are primarily accessible by water via boat, kayak, or paddleboard, offering a direct view of the region's unique coastal geology and maritime erosion patterns.
