The PR4 - From Dinosaurs to Rock – goes from the coastal zone of Porto Dinheiro beach to the western slope of Cabeço da Pedra do Sino, also known as “Rocha” (Rock). You can choose to start the hike in the village of Ribamar or at the Porto Dinheiro beach.
When starting the route in Ribamar, it proceeds towards the coast and quickly joins the course of the GR11 E9 - Caminho do Atlântico (Atlantic Way). After a detour to the Bolineiros Clis, at the excellent beach of Valmitão, the routes continue together towards the Porto Dinheiro beach. Land of fishermen and of important paleontological findings, a visit is suggested to the beach, the former fiscal guard post and the dinosaur’s terrace. A few meters ahead, the route leaves the GR11-E9. Shortly before returning to Ribamar, we suggest a short detour to the public wash-houses of the “rio do povo” (people’s river). In the village, you can visit the Fonte Velha (Old Fountain) and the Poço da Quinta (Farm’s Well). Finally, the route goes up to the Cabeço da Pedra do Sino from where you can enjoy theexcellent coastal landscape and the view of the path you have just completed.
