Welcome to the oasis in the desert. I’m told that this oasis is the last one in Ica province. At first I thought it was perhaps a mirage, but it also had good mobile phone reception!
The main reasons people come here are to see the oasis, but also to go on buggy tours and go sandboarding.
Buggy tours are a rather interesting activity. You can strapped into a buggy while somebody from Huacachina practices driving like he is driving in Lima! Basically he goes really fast up a hill and then plummets down the other side. The buggies have large tires and a roll cage (although I would still not like to be upside down in one) so they are pretty stable in the sand. You can to stop a few times for photos and to watch the sunset.
