Andes climber (5)
I believe the answer is:
llama
'andes climber' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for llama that I've seen before include "Andean camelid" , "Pack animal, native to the Andes" , "S American animal related to the camel" , "One bearing burden" , "20vian beast" .)
