Pedras de Portimão is a large rocky structure lying on a sandy bottom and extending southwards for hundreds of meters along the coastline of the town of Portimão, with walls up to 4m in height. This structure allows for several interesting scuba diving sites, with similar characteristics in terms of environmental conditions, fauna and flora. They also offer excellent conditions for underwater photography.
- Pedra do Arco: A site comprised of two large rocky formations of more than 3m in height, sheltering lots of sea life. In its Southern rock formation there is an arch that gives the place its name ("arco") and which can be passed through without difficulty.
- Castelo de Neptuno: A relatively small, terraced rock rising up to 8m full of sea life, where it is common to see white seabream and ballan wrasse. On the top of the rock - nestled among the algae and gorgonians - you will find various types of nudibranch, offering excellent opportunities for photography.
