Duung Wetland sits near the Sinduri Coastal Dunes in Taean, formed by a water channel trapped by sand dunes over 7,000 years. Wooden information boards and viewing decks line the wetland, where water lilies and lotus flowers bloom. It is known as a habitat for the gold-spotted pond frog, and a restroom shaped like the frog stands there. The space is small, so the walking course feels short.
