Wanting to do an easy hike one day, I went to the Cajón del Maipo with Neil. After our adventures on El Plomo, we wanted to go somewhere where we almost certainly wouldn't die, so we headed for the Monumento Natural El Morado. We knew the trail there closed in the early afternoon, so we made sure we were in time, only to find that the closing time had been changed to even earlier, and we'd missed it.
So we headed further up into the mountains, to the next valley, Valle de las Arenas. Confusingly, Monumento Natural El Morado contains Glaciar San Francisco, while Glaciar El Morado is in the Valle de las Arenas. We drove a long way up the valley on an incredibly rough track, then hiked up to the glacier.
It was an easy hike, and from where we parked, it was less than two hours to the top of the valley, 3200m above sea level. The path crested a small rise and we found ourselves by a chocolate brown lagoon full of icebergs from the glacier. In the mountains around us there were five or six more glaciers.
