Seonam Lake Park in Ulsan has a 4.0km walking path around a lake, a lotus pond, and a playground. A full loop of the lake takes about 40 minutes to an hour, passing a small temple, a Catholic church, a Protestant church, a rose tunnel, and an artificial climbing wall. The Rainbow Playground is open from 9 a.m. to 6 p.m., with pavilions, benches, and a snack bar in various spots. The entrance on the Gaeunpo side has few signs, so it is hard to find on a first visit.
