The Firehole Falls is a cascading waterfall with one drop. The waterfall is located in Yellowstone National Park within the Firehole Canyon. The falls can be seen from Firehole Canyon Drive, which is a one-way street.
The Firehole Falls is known for its trout fishing. The falls themselves were originally a barrier to fish and no fish were found in the river located above. However, in 1889 brook trout were placed in the river above the falls. Brown trout were also introduced to these waters. In the early 1900s, rainbow trout were introduced into the river. Even though the falls still blocks fish migrations from the Madison River, the upper Firehole is one of the best places to fish for trout.
There is no historical documentation as to how the falls got their name. The falls were first mentioned in history in the 1871 when Lt. Gustavus C. Doane of the U.S. Army set a report back to the Secretary of War. In the mid 1880s, Firehole Falls were routinely called by that name in various military and domestic reports and the name stuck.
The Firehole Falls is an easy level hike and it is worth stopping to see while see the other sites within Yellowstone National Park. Fishermen will enjoy the challenge in catching trout in the Firehole river. The season for the falls is April through September.
