So, yeah, we are getting a snow tubing hill in Harpers Ferry. Don't count on any expansion of winter sports beyond that. 

It's on the western slope of Bolivar Heights, facing Schoolhouse Ridge and on the south side of US340. If you know where the Clarion Inn/White Horse Grill is, it is just below it. River Riders has had a zipline on the same slope. 

It does not come anywhere near the river, icy or not. 

River Riders was a terrible outfitter IMO.  After experiencing the ones up in Ohiopyle, they were a huge step down.  Equipment sucked and all the guides did was kvetch about tips.  Probably the only time I ever gave a crappy tip to a river guide.

I'd sooner drive up to Liberty before I ever go there again. I think the distance is roughly the same.
