This cache is a box full of books. You are invited to take a book and left another one. Also, the objectif of this cache is to invite you to a nice hike in the Montachique hills.
Go to Montachique village by the A8 highway. Follow the waypoints passing by the villages; Cabeço de Montachique, Tocadelos and Salemas. Park your cachemobil at the proposed coordinates Park 1 or Park 2 (depending on your cachemobil). Visit the cave Gruta das Salemas (don't forget a lamp). This cave is referred as a place where vestiges of the Neanderthal Age were found. It has about 30 m and is safe to explore. Then walk to the cache place following the reference points in the file. The final part is tuff, an inclined ascent. From RefPoint4 to the cache, only Geocachers phisically skilled can do it. Also, MTB/4WD vehicles can't go further. The area is full of aggressive shrubs. Wear mountain shoes and clothes that protects your legs and arms. Take water with you too.
I choosed the place based on a nice hiking book called Portugal Pé ante Pé, Livros Forum Ambiente, Bertrand Editora.
A plastic box (40 x 25 x 20cm) with; Logbook, stash note, pen, documentation about the hike and some nice books for you to exchange ( Please, list the book you take and the book you left, in your log.).
Don't forget: "Cache in, trash out" and Leave No Trace
