Elephant Trunk Hill is a famous landmark in Guilin, named after its resemblance to an elephant drinking water from the Li River. This natural rock formation is a symbol of the city and offers a beautiful view of Guilin's skyline. You can climb to the top of the hill and enjoy panoramic views of the surrounding area, including the river and the city's skyline. There's also a cave within the hill called Water Moon Cave, which is worth exploring for its unique rock formations and ancient inscriptions.
