Taşyaran Valley , which is 45 km away from the city center on the Uşak-İzmir Highway ; It was formed as a result of water, wind and tectonic movements. The rocks that cover the valley and take on different colors starting from the ground seem like a painter's color palette.The indented and lacy formations that the stream has eroded over thousands of years are beautiful to inspire sculptors and painters. In addition to the water, materials such as gravel carried by the stream are thought to erode the rocks. Many of the small ponds in this area are filled with gravel brought by the water. The water entering the cracked systems of the valley opened by earthquake faults has been ground like a mill with strong currents and the pebbles it carried, and created such extraordinary shapes over thousands of years.
