What time does Old Faithful erupt?
Old Faithful erupts on the average of every 70 minutes. The length and strength of the preceding eruption is used to calculate the next expected eruption. Most public locations within the Upper Geyser Basin (which is where Old Faithful is located) post that time as soon as it has been calculated giving a +/- time within 10 minutes. (Our guides on the Old Faithful Tour schedule the day to ensure you spend enough time in the Old Faithful area to see an eruption and explore.) If your interests are Geysers and Thermal Activity, then you will want to visit the area south of Madison Junction. This would include the Lower Geyser Basin, Fountain Paint Pot, Midway Geyser Basin, Biscuit Basin and the Upper Geyser Basin or Old Faithful area. There are many geysers to watch and enjoy besides Old Faithful and many that are more spectacular. Beehive is tremendous, as is Castle, Giant and others. This total area is filled with geysers, hot pots and pools that are beautiful and fun to enjoy.
