Trail Overview

Starting from the Onna Village Museum, the trail meanders through historical sites and natural attractions. One of the first notable segments is the Hiyagonbira Stone-Paved Road, a well-preserved portion of the Kunigami Hōsei Kaidō, a historic route dating back to the late 15th century. This stone path, ranging from 1.5 to 3 meters in width, offers a glimpse into the island's past and is said to have been the site of a battle during the Satsuma Domain's invasion of Ryūkyū in 1609.

Historical Landmarks

As you continue, you'll encounter the Nakadomari Ichirizuka, an ancient milestone mound that served as a guidepost for travelers. These mounds were traditionally erected at one-ri (approximately 3.9 kilometers or 2.4 miles) intervals. The Nakadomari Ichirizuka consists of two mounds: one on the north side, utilizing natural features and a Ryūkyū limestone hill, and one on the south side.

Further along, the trail leads to the Ishibashi Stone Bridge, an elegant stone arch bridge spanning the Yaga River. This bridge is a testament to the architectural ingenuity of the Ryūkyū Kingdom era. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Kunigami_H%C5%8Dsei_Kaid%C5%8D?utm_source=openai))

Natural Attractions

The trail also offers access to Cape Maeda, a renowned spot for diving and snorkeling. The cape is famous for the "Blue Cave," a naturally formed cave created by seawater erosion, known for its mystical blue glow caused by sunlight reflection. Even without entering the water, visitors can enjoy panoramic views of the East China Sea from the observation deck. ([skyticket.com](https://skyticket.com/guide/55182?utm_source=openai))
