It took me a bit more than 7 hours to get to the summit from the high camp (5950m) during my solo expedition "3 Cruces, 3 cumbres", on the classic normal route located on chilean side. The last 350m are a tough ascent through very big and unstable rocks. Finding "the gate" (6626m, S 27°05.824' W 068°46.871)is not that difficult on the way up but it is quite tricky while going back down. The day before, I was climbing Tres Cruces Central and two days later, Tres Cruces Norte. Beautiful and remote place. On this summit, I found (in the Banco de Chile box) few climber's log, and among them, the only person who apparently also climbed the three summits is Corax.
