The Ozaisho Pond and Akamatsu Pond walking trail is a 1.5-kilometer path, a hiking course taking about 45 minutes one way. Nearly halfway along the trail, visitors will find "Ozaisho Pond" and the small "Akamatsu Pond" (also called Goshikino Pond), with a small observation deck conveniently located for resting and viewing these two ponds.
Akanuma, as its alternative name "Goshikinuma" (Five-Colored Ponds) suggests, changes color five times throughout the year as the seasons shift. During summer, its waters transform from cloudy blue to vivid blue, then to turquoise. In autumn, they revert to cloudy blue, and in winter and spring, they turn brown.
Wetland plants bloom along the walking paths from spring through midsummer. Skunk cabbage flowers from April to July, water crowfoot from May to August, cottongrass and dwarf rhododendron in June and July, and deer cabbage in July and August. Come autumn, the landscape bursts into flames of red and orange with the autumn foliage.
Please note that there are no water sources or restroom facilities along the walking path.
