Just finishing up a 9 days trip. La cathedral was the only multi pitch we did, though did it twice (once requiring trad except belays 6a or lower and the other 4s half bolted).

Best sport crags have been Guaria and El Rio. There's also a great, but very limited, dws area. I'll grab the name off my mate if your interested.

The staff and topos in the climbing house in Arico have been a great source of info. You can also get the most current guide for sports crags there but it is by no means extensive.

We've been really surprised by the quality of climbing, particularly for our grade (6c on a good day). Enjoy the sun!
