Old Faithful

Old Faithful geyser is, of course, the best-known feature of Yellowstone National Park, though it is neither the tallest nor the most regular of the geysers in the park. Nonetheless, because it erupts nearly every hour and because it is near the main lodge there is always a crowd there. The rest of the geyser basin is usually less busy and has many features that are as interesting as Old Faithful and it is worth spending time there, if one can find parking during the busy season.
