Hi Attila,

That is certainly true around the geyser basins. This is for your own safety. Many people have died or been injured in the geyser area by falling into scalding water. People forget that Yellowstone is essentially a giant volcano - which explains why things like Old Faithful and the other hot pools.

Having said that, the park is pretty well marked out after all of these years. There are mNy places to go unencumbered, and i suggest that the best way to see Yellowstone (or any park) is exactly as you suggest - off of the beaten path.
