Buffalo Eddy sits on the Snake River along the Idaho–Washington border, where the water bends and slows and hundreds of images are carved and painted onto the dark basalt. It is one of the units of Nez Perce National Historical Park, and the rock art was made by ancestors of the nimíipuu (Nez Perce people). For RV travelers following the Snake River, it is a quiet, powerful stop that asks for care and respect rather than crowds.
Best season — Late spring through fall (confirm river-road access with NPS)

On the ground
The National Park Service describes hundreds of distinct images at Buffalo Eddy — petroglyphs pecked into the basalt and painted pictographs — that, per NPS, may date from as early as 4,500 years ago and continue to just a few hundred years ago. The imagery includes naturalistic bighorn sheep, elk, and deer alongside human figures and abstract designs.
The NPS message here is unambiguous: leave petroglyphs as you found them, and do not etch or paint over them, pry them from the bedrock, or disturb them in any other way. Digging, collecting, or damaging these resources is a felony punishable by fines up to $100,000, imprisonment, or both. This is sacred nimíipuu heritage.
Treat the visit as take only photographs and leave only footprints. Stay back from the panels, never touch the rock, and give the place the quiet it deserves. Confirm road access, river conditions, and any seasonal notes on the National Park Service site before you set out.
