Koboke Gorge Rim Trail (Mount Kamegamori approach)

The Koboke Gorge Rim Trail begins a 5-minute walk from JR Koboke Station, making it one of the more transit-accessible hikes in Tokushima's Tsurugisan Quasi-National Park; no permit is required and parking is available near the station for those arriving by car. The trail runs 3 km one-way along the rim above the Koboke Gorge on the Yoshino River, gaining roughly 100 m as it climbs toward the Mount Kamegamori approach, with most hikers retracing their steps back to the station rather than continuing to the summit. The path is a gentle dirt and gravel rim trail with partial tree cover, alternating between open viewpoints over the gorge and shaded forest sections; there is no scrambling or technical difficulty, though the rim sections have real drop-offs and are not fenced. Landmarks include several signed overlook points above the Koboke Gorge's swirling river channels, a junction where the trail continues toward Mount Kamegamori for hikers wanting a longer outing, and views of the Yoshino River gorge boat tours passing below. The signed junction toward Mount Kamegamori is a natural turn-around point for those doing the rim walk only. There is no water source along the trail; the last opportunity to refill is near Koboke Station before setting out.
