I have been to Hatfield McCoy Quite a few times & will be going in June,Little Coal River Trail is a good trail to start out on there are some easier trails there as well as more challanging ones,It is the only trail system without a town connector so you can't ride into town (Mostly due to a issue with crossing busy 4 lane Hwy.119) There is a Campground (Forgot The Name) & Katherens Kabins (Where We Stay) Not sure about the pet you would have to call & Check,As far as Rentals of ATV'S I don't think anyone is currently doing rentals do to people destroying the rentals,As stated above visit
