The Jeju Tourism Organization's Visit Jeju describes Olle Route 17 as a 17.9 km, moderately difficult trail starting at the Gwangnyeong-ri office and taking about 6–7 hours. It goes via Musucheon, Woldaecheon, Naedo's pebble beach, Iho Tewoo Beach, Dodubong, Yongduam, Jeju Mokgwana and Gwandeokjeong, ending near Dongmun Market. The coastal walk differs from the uphill stretch over Dodubong. Visit Jeju mentions a wheelchair-friendly section near Yongdam Leisure Park towards Yongyeon Bridge, but this does not make the entire route wheelchair accessible. Check access to each segment independently. Allow daylight for a full-day walk and bring water, comfortable shoes and protection from coastal wind. The official tourism listing warns that diversions and route changes can occur, so verify current Jeju Olle trail information.
