Embark on a 4-hour adventure in the Arrábida Natural Park. Overcome natural obstacles with the help of a guide. Descend cliffs, walk along little-known trails, and climb using a rope technique.

Meet your guide and set off on your adventure. Walk along the 700-meter-long “Fenda da Arrábida”, a tectonic fault that opens along the southern slope of the Serra da Arrábida, overlooking the beach of Portinho.

Overcome natural obstacles such as cliffs and confined spaces. Descend using a rope technique, with descents ranging from 10 to 30 metres. Walk along little-known trails, climb using a rope technique with a 100-meter extension, and cross confined areas.

If you're lucky, you might even see some bats.
