The Taehwagang River cuts across the heart of Ulsan City and flows into Ulsan Bay, which is connected to the East Sea. The river basin, which stretches 36 kilometers from east to west and 28 kilometers from north to south, is mostly comprised of mountainous terrain, but there is fertile land on both sides of the river and at the southern end of the river. The Taehwagang River is presently an important source of drinking water for the citizens of Ulsan. Taehwagang Simnidaebat is an extensive bamboo field covering the areas between Taehwa Bridge and Samho Bridge along the Taehwagang River. The bamboo field, which is about 4 kilometers long and 20-40 kilometers wide, was created by the villagers in hopes of preventing the frequent flooding that occurred during the Japanese colonial period. Today it is a rich bamboo forest. In spring, the flowering plant garden in Taehwagang Grand Park offers splendid scenery created by over 60 million spring flower blossoms from 7 different species that include poppies, cornflowers, and golden coreopsis. It is the largest single riverside flowering plant garden in the country.
