Located in the heart of the Sintra-Cascais Natural Park and the Natura 2000 Site of Sintra-Cascais, this trail stands out for its stunning, rugged coastline, with the Sintra Mountains in the background. Starting at Malveira da Serra, the route passes through Janes and Charneca, heading towards the coast and continuing by the Forte do Guincho before reaching Praia da Grota. From there, the trail veers inland and returns to where it all began: Malveira da Serra. Along the way, keep an eye out for the local wildlife, which is often hard to spot: wild rabbits, foxes, weasels, lizards, snakes, and their predators, such as kestrels, barn owls, little owls, round-tailed eagles, and rock doves. If you look up, especially around the cliffs, use binoculars to catch a glimpse of the common kestrel, peregrine falcon, blue rock thrush, or seagulls.

As for the flora, the local conditions allow Mediterranean plants with medicinal and aromatic properties to thrive, such as mint, chicory, fennel, oregano, honeysuckle, St. John's wort, and rosemary. Bring along a notebook and take note of your discoveries.
