Old Faithful is one of many geysers that can be found in Yellowstone National Park. What makes Old Faithful special is its very predictable pattern of regular eruptions, every 45 to 120 minutes, and when it erupts it throws between 13,000 to 30,000 litres of boiling water 40ish metres into the air.

The site is also home to the Old Faithful Inn, one of Americas oldest Log built park lodges and is really impressive to visit
