The park is packed with families — especially around Old Faithful (just one of the park’s 300 geysers) and in the new children’s discovery area at the Old Faithful Visitor Center. The National Park Service says the vast majority of visitors don’t get more than a quarter-mile from the road though only about 3 percent of the vast park can be seen from that vantage point. That was why we opted to let Austin-Lehman lead the way.
