After telling Eduardo about the geocaching, he got so interested that we decided to hide a cache close to the place where he works to assist the cache frequently.
The cache is hidden close to Lago Grey and marks the right way to the icebergs. I made the mistake to walk directly and found the river, which took me a lot more time to reach the "mirador".
After going over the hanging bridge, walk the way until you locate the rock. There are some cavities at the ground where we found a perfect place. Look on the left side of a cavity and you will see the zip bag containing a logbook, Eduardos Data for contact, some EURO coins 2x50 argentinian centavos, 2 spare zip bags and a green pencil.
Remember to bring moskito repelent!
Small note on cache maintenance: Eduardo works in the hotel and takes care of the cache.
