The bumper boats area is dismally small and the mini golf area looked decent but you need to face facts, this place is all about the sand dunes.
We took that half hour tour and it was worth every penny. It was absolutely amazing, the views, the speed, the angles they take the buggy on will blow your mind. And it’s informative too.
When you buy your ticket(s) make sure to get some advice regarding attire and cameras and then follow that advice to the letter if possible. Every inch of exposed skin will get a slight exfoliation care of the sand and the wind. Cameras should be kept in a zippered pocket and only brought out when stopped and even then you probably don’t want to bring your most expensive piece of equipment.
This is one of those experiences that you actually have to do, it’s difficult to describe and nearly impossible to do it justice with mere words. If you’re in the area do this at least once, you won’t regret it.
