Benham Falls is a scenic cascading water fall west of Lava Lands Visitor Center on the Deschutes River, or the “River of Falls” as French explorers named it. Two trails start at the parking lot. A short interpretive trail goes upstream and deals with the railroad logging industry that flourished in the Central Oregon during the first half of the 20th century. The other trail goes down stream to Benham Falls and follows the old mainline Shevlin-Hixon railroad grade.
Prior to the eruption of Lava Butte, the Deschutes River occupied a canyon (80 to 100 feet deep) from Bend to a point several mile upstream from Benham Falls.
Lava flows from the eruption of Lava Butte 7000 years ago reached the Deschutes River and filled the existing canyon from the Benham Falls area to Dillon Falls with more than 100 feet of lava and formed a dam. The river backed up to form a lake which extended south through the Sunriver Area. When the lake reached its maximum depth it spilled over a low saddle on Benham Buttes and began to cut the channel that today is known as Benham Falls.
