The Gwanbuk-ri archaeological site and Busosanseong Fortress at 15 Buso-ro, Buyeo, form part of the Baekje Historic Areas. KTO's accessible-travel listing mentions three wheelchairs at the main-gate information desk, an entry ramp and an accessible restroom near the parking area.

Accessible entry does not mean the entire hillside is accessible. The routes toward Nakhwaam Cliff and Goransa Temple are specifically described as steep, rocky paths difficult for wheelchair and stroller users.

Listed hours are 09:00–18:00 in March–October and 09:00–17:00 in November–February. Families and mobility-aid users should plan around the accessible entrance and confirm which sections are usable before visiting.
