Ttangmoesan Hwangto Supgil is a hiking course beside the Hoedong Reservoir in Busan where visitors walk the yellow-clay path barefoot. The route follows the reservoir past cypress groves, a bamboo forest, and boardwalk sections. The clay path takes about 20 to 30 minutes round trip, and at the end there are foot-washing stations and an air-pressure dust-removal facility. There is no separate free parking lot, so parking is inconvenient.
