Tennyogahara Marshland Trail

Along the hiking trail, which is approximately 3.4 km from the starting point of the trail near the cable car Sanroku Station to the footpath around Sugatami-no-ike Pond, and has a height difference of 550 m (hiking time approx. 2 hours), you can enjoy the changes in flora across different elevations and a view of the Tennyogahara Marshlands. The Tennyogahara Marshlands are classified as a high moor, where only limited types of flora can grow. High moors are oligotrophic marshlands that are sustained solely by rainwater. They are characterized by withered sphagnum moss that turns into peat because it cannot be broken down, and is not fed by groundwater since large amounts of peat accumulate, forming mounds that are higher than the rest of the area. In addition to observing marsh plants such as tsurukokemomo (cranberry), watasuge (hare's-tail cottongrass) and mousengoke (round-leaved sundew), the Tennyogahara Marshlands are perfect for observing wild birds such as komadori (Japanese robin).
