The 'turtle' rock is a naturally eroded granite boulder that has become the iconic landmark of the beach.
The water clarity is attributed to the sandy substrate and the presence of seagrass meadows (Posidonia oceanica) nearby.
Cala Girgolu is situated within a coastline stretch that transitions from sandy beaches to rocky promontories.
The site provides a direct line of sight to the limestone massif of Tavolara island.
Cala Girgolu is a coastal destination in Loiri Porto San Paolo characterized by pink granite rock formations shaped by wind and erosion. The area features a series of small, interconnected sandy coves rather than a single continuous beach. The most famous rock feature is the 'Tafone,' a natural stone sculpture resembling a turtle located at the northern edge. The coastline faces the Tavolara Marine Protected Area, offering views of the island of Tavolara. Water depth in the coves is generally shallow with a sandy bottom, making it suitable for swimming and snorkeling. The surrounding vegetation consists of Mediterranean maquis, including junipers and holm oaks. Access involves traversing narrow paths through private and public sections of the coastline. The granite rocks here exhibit distinctive tafoni weathering patterns common to Northern Sardinia. Public parking is available near the entrance to the trail leading to the shore.
