The park contains the Arrábida-Espichel marine reserve, which functions as a biological corridor for dolphins in the Sado Estuary.
The Arrábida mountain range is primarily composed of Jurassic limestone, which creates a unique microclimate compared to the surrounding regions.
It is home to the 'Arrábida flame' (Lithodora diffusa), a shrub that is particularly emblematic of the local karst flora.
The Convento da Arrábida was built by the Franciscan Order in 1542, intentionally designed to blend into the natural rock face.
The park supports a rare population of Bonelli's eagles, a protected bird of prey species in Portugal.
Due to extreme fire risk, significant portions of the park's interior trails are closed to the public during high-temperature summer months.
The park’s underwater landscape features a 'canyon' formation, allowing for diverse marine life usually found at much greater depths.
Parque Natural da Arrábida is a protected coastal reserve situated on the northern side of the Sado Estuary. It features a rare Mediterranean scrubland ecosystem with high botanical diversity, including over 1,000 recorded plant species. The park encompasses a rugged limestone mountain range that drops sharply into the Atlantic Ocean. Geologically, it is noted for its karst formations, caves, and fossil-rich cliffs. The marine section of the park is protected as a Marine Reserve to preserve nursery grounds for commercially important fish species. Access to several beaches within the park, such as Galapinhos and Creiro, is strictly regulated to prevent environmental degradation. The area includes the 16th-century Convento da Arrábida, which is integrated into the steep, vegetated cliffside. It remains one of the few places in Europe where primary Mediterranean-type vegetation is preserved in a coastal setting.

Verify current road closures or beach access restrictions on the ICNF website before arrival, as rules change frequently during peak season.
Carry sufficient water and supplies, as facilities are highly concentrated and limited to specific beach areas.
Plan for steep terrain; the transition from mountain trails to coastal zones involves significant elevation changes.
Attempting to drive to the most popular beaches during summer weekends, as road access is frequently restricted to shuttles.
Access to specific beaches is limited during the summer months due to traffic and environmental capacity controls.
Stick to marked trails to prevent erosion and avoid disturbing sensitive flora; wild camping is strictly prohibited.
