Wandering among the thermal features of the Upper Geyser Basin in Yellowstone National Park is a must-do activity when visiting Yellowstone National Park. After exploring the basin, a short hike up to Observation Point gives a different perspective.
From the Old Faithful area, the footpath leads over a bridge to cross the Firehole River to Geyser Hill. Just after the bridge, take the signed trail to the right up the hill. Switchbacks and steps make the climb pretty easy up to the hillside clearing overlooking the whole geyser basin. Expect a good crowd up here around the time of an Old Faithful eruption. From up here the geyser dwarfs the people filling the viewing stands nearby and shows how large the geyser really is. Beautiful views of the entire Upper Geyser Basin and beyond are a great reward for this climb.
