Sandboarding in Huacachina is well worth it, even just for the impressive views over the sand dunes. We took a taxi from Ica and the taxi driver took us to a hostel called Huacaf***ingchina where we could book a tour. Don't go with this company. The sandboarding tour was 90% dune buggy and 10% sandboarding and even though the lady in the shop said the guide would help us learn how to do sandboarding he really wasn't any help at all, even when we asked. The boards are ancient and you can't even attach them to your feet properly. The dune buggy ride is like a rollercoaster ride, so be aware if this is not your thing. Not only that, my seatbelt came undone while the guide was driving which was really scary. The worst part of it was, when I told the guide the seatbelt wasn't working (so he could maybe get it fixed before the next tour) he just shrugged. A really disappointing and actually quite dangerous trip.
