"We are located in the Northeastern part of Tennessee, in Sneedville, TN, just 10 miles off 25E, between Morristown and Tazewell. This is a privately owned park that has designated open rides throughout the year. It is a 20 acre natural ROCK playground that will challenge any vehicle and driver capabilities. We have some of the best rockcrawling in the SE, this is not a place to trail ride or joy ride with the family -- it is pure hardcore crawling, (expect body damage and parts breakage, so come prepared). Roll cage and seat belts are mandatory. A place like this to ride is priceless, so -- FREE admission. Contact: (423)300-9146 Jeff Ferguson."
