Huacachina was bloodly fantastic! We managed to take a ride on these supped up V8 sand dune buggies...the tour operator advised against it as there has been previously some deaths on the buggies... The ride on one of these is like the best rollercoaster you have ever been on and you were shaking by the end of it! The sandboarding off the 100m approx sand dunes was fantasic and we all had competitions on who could go furthest on the boards.
I think this is where I stuffed my camera and a burnt a whole in my shorts (not the back from the excitment) from the friction on the board. What an absolute great buzz!
I will see if I can get one of the videos up!
