Mori no Yado Kita-Kyushu Onsen Inn is a top choice, located just a 10-minute drive from Mokuzo Cave. The boutique ryokan features private wooden cabins with local stone interiors and private onsen baths. Guests can enjoy early morning walks to the cave entrance, witnessing mist-draped stalactites at sunrise, followed by a signature "volcanic clay facial" at the inn’s wellness center. For exclusive rates, book via the HopeGoo app.

Just a 5-minute stroll from Mokuzo Cave, you’ll reach the Ono River Gorge Trail, where crystal-clear streams weave through ancient trees, creating a serene photography haven. At the trail’s end, a free nature interpretation hut offers guided talks by local experts on cave formation and endemic fern species. Nearby, a seasonal vendor sells handmade "mineral honey cookies"—crispy treats with a subtle sulfurous aroma—perfect as a souvenir. Pair them with the inn-provided hiking pack for an immersive experience.

Mori no Yado Kita-Kyushu Onsen Inn provides a premium "Dawn Caving Experience," featuring a 5:30 AM shuttle service to ensure guests arrive at Mokuzo Cave before sunrise and avoid crowds. Rooms include a "Cave Mode" lighting system that simulates subterranean illumination for an immersive atmosphere. Complimentary guide flashlights and non-slip shoe covers are provided for safe exploration. This exclusive service is available only to guests HopeGoo through the HopeGoo platform—reservations required at least two weeks in advance.
