Dongxi Scenic Area has lots of pretty rock formations, canyons, caves and temples. You can take a circular hiking route that will take maybe 1.5 hours (there's lots of signage everywhere) or just go explore for hours. There's a restaurant and tiny gift shop by the entrance and some small stalls at various points along the trails.
