The rocks and landscapes of the Algarve house 400 million years of stories. Sagres region is incredibly geodiverese, with sites that are regional, national and international reference-points.
At Salema and Santa beaches you can see dinosaur footprints, but there’s other evidence of the region’s past. There are fossilised coral reefs at Carrapateira and at Mareta beach, which also has fossilised dunes. The latter can also be found at Castelejo beach.
The passage of time is also visible in the limestone pavements – a lattice of limestone crafted by erosion – and pit caves on Sagres platform.
At Boca do Rio (Salgados beach), there’s evidence of the tsunami that destroyed Lisbon in 1755.
