To the credit of the negative reviews, this guide does just stay on a road that is accessible to anyone in their own car. But the point of this tour, to me, is not the driving but the guide. You get access to someone who’s super knowledgeable about the area and can tell you all the things that Google won’t. Plus they do take family pics, which to some people is really important. Our guide, Rene, hit every mark. She was worth 2x as much as we paid! So if you’re brand new to the area do this first thing and then go back in with a better idea of what to do.
