The area is home to the rare Aleppo pine, which grows naturally in only a few locations in Sardinia.
The five beaches within the oasis are numbered sequentially, each offering slightly different sand types and sea depths.
The lagoons inside the reserve are interconnected with the Gulf of Orosei, allowing for a unique brackish water ecosystem.
The reserve is part of a larger network of protected areas designed to mitigate coastal erosion in the Orosei region.
The specific flora in the park includes strawberry trees (arbutus), mastic bushes, and wild lavender, which contribute to the local air quality.
Oasi Biderosa is a protected coastal nature reserve on the Gulf of Orosei consisting of five distinct beaches and 860 hectares of Mediterranean maquis, forests, and ponds. The site is managed by the Cooperativa Le Oasi, which strictly limits the number of daily visitors to preserve the fragile ecosystem. The terrain includes paths through Aleppo pine and cork oak forests leading to sandy coves with turquoise waters. The preserve features internal saltwater lagoons that serve as habitats for diverse bird species, including pink flamingos. Entry to the reserve is only possible via a gated access point on the SS 125 Orientale Sarda. Visitors navigate the area by foot, bicycle, or private vehicle, depending on the current seasonal access regulations. The beaches, such as Biderosa 1 through 5, are noted for their fine white sand and shallow, crystal-clear sea. It is a strictly regulated environmental area where activities like camping and open fires are prohibited.
The elevated lookout points on the trail between beach 3 and beach 4, providing a panoramic view of the coastline.
