Twin Falls is home to stunning geography. The impressive, deep Snake River Canyon forms the boundary line between Twin Falls and Jerome counties, and houses three waterfalls within its depths. The most famous, Shoshone Falls, is higher than Niagara. It reaches its peak in spring, after snowmelt swells the river and before the water is diverted to sustain the area’s thriving agriculture. The Snake River provides easy access to outdoor recreation such as fishing, rafting, canoeing, and stand-up paddleboarding.

Twin Falls is within driving distance of the South Hills, City of Rocks, Thousand Springs Scenic Byway, and many other incredible places that beg for exploration.
