This one-way, 3-mile-long road takes you past Great Fountain Geyser, which shoots out jets of water reaching as high as 200 feet about twice a day. Rangers' predictions have a two-hour window of opportunity. Should you witness it, however, you'll be rewarded with a view of waves of water cascading down the terraces that form the edges of the geyser. This road is not open to over-snow vehicle traffic in winter, only foot, snowshoe, or skies, and is rarely traveled by any of those options because it is not groomed for those uses.
