To expand a little on what Mad River said about Livermore -
Without a pass you can use Livermore to access hiking trails. The Greeley Ponds Trail is "free" as is the Timber Camp Tr, the Scaur, etc.
If Livermore is busy , as it is on the weekends, snowshoeing for a distance on Livermore isn't so much fun. That's because many skiers also use the center strip on Livermore , rather than the tracks on each side. You always have to be on the watch for them coming fast around the corners.
Greeley Ponds is a good destination, as you get off Livermore relatively quickly and it's free of the crowds.
I love snowshoeing in WV!!
