One of the most beautiful gates I have ever passed through. When I was getting closer, it seemed incredible that you could pass by

This port is one of those accesses that when you arrive you see it impossible to climb the rocks in front of you. The thing is that it also does not have greater complexity. And the views, as good as all of the Sierra.

The complicated part is not the T1 path until reaching the track, that part is simple and pleasant. The downside is the downhill "track", which had nothing to do with "track", it had a steep slope and was quite slippery even in the dry.
