Torre de Aspa is the high point of the Algarve’s coastline: a white geodesic marker on a clifftop at about 156 metres, around 4 km west of Vila do Bispo, close to Praia do Castelejo [1]. There was once a watchtower here, part of a 16th-century coastal lookout network, but nothing of it survives; what you come for is the view [1].
From the top you look down on Castelejo’s dark cliffs and pale sand and along the west coast [2]. Sources give the height as 156 m [1][3] or note a nearby point at 157.8 m [2] — either way, the highest cliffs on this coast. It sits inside the Southwest Alentejo and Vicentine Coast Natural Park [1].
Who it suits. Walkers first: outdoor platforms recommend the detour if you are on the Fishermen’s Trail stretch of the Rota Vicentina [3]. For a nomad in Sagres it is a half-day outing on a non-beach day; for families, an open clifftop where small children need a hand held.
Getting there. Head west from Vila do Bispo toward Castelejo [1]. Whether the last stretch is drivable or a walk on a dirt track, and where to leave the car, we could not confirm from a reliable source.
Check before you go: the access track and parking; wind on the clifftop — this is fully exposed coast.
