They have 2 kinds of tours one with the dunes and another one is cheaper without dunes. I paid more because I expected that we will be actually driving on dunes but no, they just bring you there and you get off buggies because it's a national park and you are not allowed to drive there. My advice - take a cheaper option and enjoy dunes on your own

UNMISSABLE! Three hours of fun and lots of off-roading. Friendly, helpful and super prepared escorts. You will get dirty from head to toe! It is also possible to purchase the photos taken by the photographer during the entire duration of the excursion. We took them and they are truly amazing. Everything perfect, sympathy and adventure.

It was a super fun and unforgettable experience, time flew by, the views of the places they took us were spectacular, both the dunes and the volcanic area, and it was also good to drive by road, but the most fun is when They take you to the dirt roads, there we enjoy like children hahaha, what I recommend that you go prepared both with large glasses that cover your face well and a panty or handkerchief because you leave with dirt from top to bottom lol, but it's worth it, the Monitors had a super friendly treatment and are very attentive and friendly, in short I recommend living this experience to those who visit the island
