Sete Vales Suspenso [Seven Hanging Valleys] is a series of stunning geological formations along the Algarve coastline. The cliffs exposed to the sea have been chiseled-out by powerful winter storms creating striking rock formations, caves and sinkholes.
The hiking trail runs from Praia Vale de Centianes [Centianes Valley Beach] on the west to Praia da Marinha [Navy Beach] – it can be walked from either direction. The hike mainly takes place along the top of the coastal cliffs close to the edge with several ascends to sandy beaches along the route.
It is a moderate difficulty 12 km (out & back) linear trail. The most exposed stretches are fenced for safety. There are many signs painted on posts and rocks to guide the way. However, to find the hidden grottoes and secluded coves along the way, the help of experienced guides is needed.
At Praia de Benagil [Benagil Beach], visitors can opt for a boat tour and enjoy a different view of the cliffs. The trips make several stopovers at various sea caves and sinkholes including the most famous one, Algar de Benagil [Benagil Cave].
The sea along the cliffs is rough so preventive actions should be taken. In addition, taking photos in these conditions is a big challenge. In summer, it could be very busy as boat tours depart from most of the major beaches as far away as Lagos or Faro.
