Want an adventure that will make you realize just how alive this earth truly is? Hiking through the Old Faithful Area in Yellowstone National Park will do the trick. Numerous trails wind through the the area, past hot spring pools, geysers, and thermal vents. The crystal clear blue water and explosions of steam that happen at regular intervals is surreal, and undeniably beautiful.
Starting at the Old Faithful Lodge, which is a sight to see in itself, several trails start out heading away the actual Old Faithful geyser. You can take either one as they form a loop so you will eventually end up back where you started. It is a combination of dirt trails and wooden walkways that crisscross and zigzag throughout the different areas.
There are numerous thermal pools and geysers that go off at regular intervals. Signs posted lead you in the direction of whichever spring you choose. By each spring there are signs that provide names and information.
Some notable things that I wouldn't miss are the Morning Glory Spring (pictured above), Old Faithful itself (obviously) and the Beehive Geyser.
There is so much to see you could easily spend an entire day exploring the area.
Make sure to stay on the marked paths so you do not disturb the environment.
