We were not impressed with this tour. I think since they cannot go to the waterfall anymore, it really doesn't seem like there is much substance to it at all (Thanks to Mark Zuckerberg purchasing the property it is on and restricting access). Driving around and in-hailing dust and dirt at 20-25 mph isn't my idea of fun. Even my kids (9,8, & 5) thought it was pretty lame. This tour needs to be no more than 1.5-2 hours. Not 3 hours. Not enough substance without the tunnel & waterfall access.
Furthermore, I do not understand why they have Polaris RZR1000's to only go max 30mph. Seems like a waste to me. If you are an experienced off-road enthusiast and are expecting this to be what you are accustomed to, I would not waste your time.
