Not long ago, a study was done to determine which state was the "most mountainous". Not which state had the biggest mountains, but the state where it seemed that people would encounter the most mountains or most perceptibly be around mountains. That state was, to some folk's suprirse, the one that had already received the nickname "The Mountaineer State" over a century prior. West Virginia usually gets short shrift from the coastal elite as a state that is deeply backwards culturally. History says that the state was created when Unionist counties in space not particularly conducive to cotton growing within Virginia broke away as a result of the US Civil War. In the late 19th century and early 20th century, West Virginia was home to much of the violent fighting between mercenaries hired by coal mines along with occasional assistance received from the US Army (including aerial bombardment!) against newly unionized workers seeking higher wages and safer conditions.
Yes, West Virginia has problems. That's what happens when the infrastructure for your area is largely left up to the state to fund and there's no flat land anywhere. If it wasn't for deals worked out by (former Klansman and future Democrat) Senator Robert Byrd via "pork barrel spending", who even knows what the state would resemble in terms of rail lines, freeways, and buildings. West Virginia probably needs a lot more of that long term to become more sustainable, if that is even a possibility.
Those ancient days of labor union fighting coincided with a period of of small trolley companies and their amusement parks. West Virginia had many such parks - I did some light research and came up with the names of 15 long, long gone parks. Some of these had closed a century ago with nary a sign of their existence except a road that had never been renamed. Only one park remains in the state - Camden Park, a 116 year old ex-trolley park built by the Camden Interstate Railway Company along the banks of the Ohio River. The park long appeared on the endangered list - I remember going there for the first time and seeing the long defunct Thunderbolt Express Arrow Shuttle coaster sitting there in an advanced state of decay - but has seemed to turn around with some reasonable investments and clean up. Camden is even making an unexpected appearance in a video game - Fallout '76.
With so few permanent facilities in the state, we should go about mentioning the largest single collection of amusement rides the state sees: the West Virginia State Fair. Reithoffer sources the rides at present, and this year's event will see 3 coasters going up, along with a pile of flat rides.
West Virginia has a few small water parks: Waves of Fun in Huntington and Water Ways in Julian are the main outdoor facilities the state has. ACE Adventure Resort in Oak Hill has a "water park" in so much as they have a swimming hole with a bunch of big inflatable things in it to climb on or jump off of. More interesting is the "non themed" attractions they have - walking the maintenance paths inside the New River Gorge Bridge, spelunking, zip lines, and white water rafting.
Finally, Wheeling's Oglebay Good Zoo is not only AZA accredited and alone in the state as such, but home to a train ride that's pretty lengthy and leaves the zoo itself to wander into the surrounding 1650 acres of Oglebay Park.
