The Tagus Estuary Nature Reserve (RNET) is located in an area of high natural richness and diversity. Covering approximately 14,415 hectares, it is integrated into the largest wetland area in Portugal – the Tagus Estuary, including estuarine waters, sandbanks, salt pans, agricultural land, and cork oak forests. The connectivity of these habitats ensures the presence of a great diversity of living beings, such as mollusks, crustaceans, and small amphibians. It is also a nursery for various species of marine fish and a very important ecosystem for migratory fish. The estuary is also of great importance to aquatic birds, being one of the places with the most wintering birds in Europe.

Section of the path on a gravel road that runs alongside the wind farm. The feeling of walking next to a large rotating wind blade is interesting to say the least. Panoramic views of Serra da Archeira.

Forte da Archeira, part of the Lines of Towers defensive north of Lisbon during the Peninsular War, is a military fortification located at an altitude of 345 m. It was part of the 1st Defensive Line with the forts of Catefica and Feiteira. Despite not having gunboats, it has traces of a magazine. It forms part of the Lines of Torres, a system of 152 fortifications stretching over 80 km, built between 1809 and 1812 to prevent the advance of Napoleonic troops.

At the top of Mount Mecca, there was once, I believe it was still working in the 90s, a basalt quarry. it has been closed and has barbed wire to prevent people from entering. As I found out, there were people who went there to bathe, but there was someone who cut part of that fence, and you can get there by bike. The panorama is amazing...

This crater is located in the place usually known as Cabeço de Meca or Cabeço de Santa Quitéria, and is classified as having been a volcanic chimney. This chimney, which was operated as a quarry for the extraction of basaltic material for years, is currently unprotected, as a result of the impasse caused by the PARP, leaving visible the industrial structures that support this extraction, such as a lake in the center of its crater, also a consequence of the same exploitation.

This waterfall is normally dry after 1 month of rain season, so by late march or early april it is normally dry. Then it should have water by november.
