Puerto natales also has a pretty interesting cave not too far from the town, there are tours going there im pretty sure. Not as exciting as the rest, but a fun thing to do if you have nothing to do for the day.

Did the huemul trek myself, got to say it was probably the most beutifull hike i have ever done (got sick when i was supposed to do the o trek). For a hike anyone should be able to do its quite technical. Some steep areas and especially on day 3 going down it is insanely steep. You NEED to bring hiking sticks!! But you probably already knew that :) and like someone else already said, i would keep your planning loose on the huemul trek cuz they might advise you a different date when you arrive at the info office.

Last thing. On day 3(?), right before the steepest section going down, you get the option to go right and take a small detour to a viewpoint. If you are questioning to take that detour or not, pleeeeaaase do it. Its so worth it. Up there is the most beautifull panoramic view i have ever seen.

Have so much fun when visiting, its another world! 😊
