If you are considering booking a tour with Fisher's, stop thinking about it and book it now!! You will not regret it. My sister and I took the 4 hour back country tour and loved every single minute of it. The staff are the absolute nicest people! They are well versed in their vehicles, the history of the land, and the terrain itself. They make sure all riders are comfortable and feel safe and know how to properly operate their vehicle. During the tour, your guide communicates with you the whole time to make sure you are aware of what is upcoming and preps you on how to get through the tricky (aka most fun) spots of the ride. Our guide, Kevin, was an absolute gem, and I'd venture to guess all the other guides are just as great. I would not hesitate to book another tour with Fisher's if/when I'm back in Nashville.
For future riders: You WILL get wet. Wear weather appropriate clothes/shoes for this. You could consider a poncho, but I'm not sure how well that will help. Bring a change of clothes, including socks and shoes, so you don't have to ride home in wet clothes. Relax and enjoy it. Splashing through the water is one of the best parts of this adventure!
