There are no off road trails in Yellowstone NP. The closest thing is a gravel road on the Blacktail Plateau in the northern section of the park. However it's a one way road, maybe 12-14 miles, that runs parallel to the main road. The scenery is great, but it can be done in a sedan.

Traditionally the main roads in Yellowstone do not open for vehicle traffic until Memorial Day weekend. With as much snow as we've had this winter, even Memorial Day may be pushing it. There was a story in the local papers last week about 2 of their monster snow pushers breaking trying to clear the roads. I make a trip to Yellowstone every Memorial Day weekend and it is always, always cold. Like below freezing temps cold, and with tons of snow still on the ground. Be prepared.

Not trying to kill your buzz, but a call to the Yellowstone and GTNP ranger stations regarding current conditions would be a very good idea.
