Found it marulhar
Aí está uma cache bem antiga da região de Lisboa, uma pioneira nesta serra da Carva e ainda sem rival que lhe faça sombra!
Talvez pelo "peso histórico", imaginei dificuldades muito maiores do que as que vim encontrar... De facto, quer a cache quer os acessos à gruta são evidentes para qualquer pessoa minimamente atenta às pistas que se inscrevem na paisagem.
Gostei muito do local e de toda a envolvente natural. Não fiz trocas.
Obrigado!
Found it MAntunes
In this hunt Mantunes & Snoopy, again, accompanied me.
This cache, close to the "Toca do Gato" cave, is located in a very beautiful region, near Lisbon, that make us put out of our minds the preoccupations of our life.
The place is very cool, with a great view over the surrounding hills and over Lisbon, and with many geologic curiosities.
The cache wasn’t easy to find, cause is hidden in a not so obvious place.

Out: Only the trash...

Found it :-) Welll... this time with the help of "PH".
We had this hunt settled since we were in "Half a Mountain" and, when time arrived here we go!
We parked the car where suggested and walked as suggested until half the way. After we turned to the left and took the way proposed to the returning. When we arrived to the spot, we decided that this time I should be the first to search. "PH" remained far from the area while I was searching, searching... after half a hour, I decided to stop and give "PH" the opportunity to search the cache while I stepped out to gave drink to "Snoopy". After a half a hour, "PH" gave up and we decided to search as a time. We started thinking together, thinking, thinking... and we decided to change the startegy. It only take us 10 minutos to find it. At a given moment, we where trying to search in the same place but starting from diferent approaches... "PH" found it first!
About the place, I must say that when we was climbing the hill, we noticed that it seems that we were entering another "world" and I commented out to "PH" that one only need to pretending that no cars noise could be ear there. The lanscape is perfect (and we got a perfect day!). Very nice place and we trully enjoyed it.
In the cache logbook, we saw a visit not reported yet in this cache page.
Thanks "PH" for your company and thanks "CLCortez" for this very nice cache.
