Sometimes it makes you angry to arrive at a mountain without a summit or a mailbox... this is not the case of Aldamiñape, with a "huge" monolith that looks like the entrance to a sanctuary.

It is beautiful, but the location in which it is situated is truly privileged.

Beautiful, magical place. The final stretch is difficult to access. Not suitable for everyone. Very steep slope and lots of loose stones. The ground is also quite rocky, so on rainy or humid days it has to be very slippery. Otherwise, it is beautiful and you can take it easy and enjoy it.
