Oze National Park, located in Katashina, Gunma, transforms under autumn’s touch, as fiery reds, glowing oranges, and golden yellows set the landscape ablaze. This hike presents a rewarding balance between accessible trails and the raw power of a fiercely independent wilderness that demands respect and preparation. The main route begins at Oze-numa, a marshland lake where the crisp air carries the scent of pine and damp earth, daring you to leave behind city hums and step fully into the quiet roar of nature.

From the trailhead, expect a 12-kilometer loop combining boardwalks and rugged earth paths, with an elevation gain of roughly 300 meters. The terrain alternates between flat, easy stretches across wetlands and moderately steep ascents to viewpoints that open up to panoramic visions of the surrounding mountains cloaked in autumn splendor. As you progress, the forest edges notify you with rustling leaves and the swift passage of winds playing in the treetops—nature’s own drum signaling the changing season.

Practicality calls for sturdy, waterproof boots and layered clothing. Even though the trail is well-maintained, early autumn mornings bring dew-soaked ground that can challenge footwear grip. Carry sufficient water; the cold can deceive your thirst levels but staying hydrated is key. Timing your hike starting mid-morning not only avoids early fog but aligns your arrival at vantage points with clearer skies, perfect for absorbing scenic views and capturing photos.

Along the way, the marshes are alive with buzzing dragonflies, while the distant peaks seem to stand guard, fiercely themselves and quietly observing your passage. Don’t rush—the rhythm of the park is deliberate, inviting you to notice the subtle colors flickering through the branches or the playful dart of a bird startled by your presence.

By late afternoon, descending the trail offers softer light and the gentle coaxing of shadows, guiding your steps back toward the start, completing a memorable circuit. Autumn in Oze isn’t just about seeing colors; it’s about experiencing a living world that pulses with challenge and beauty alike. Preparation, respect, and curiosity will turn this hike into an adventure grounded as much in the practical as in the poetic.
