Explore Gyeonggi and Gangwon Suwon and around Incheon The West Sea Islands The Demilitarized Zone Chuncheon Sokcho and around Seoraksan National Park Gangneung and around Jeongdongjin Samcheok and around Taebaeksan to Chiaksan Share To the south of the island is Jeondeungsa (전등사), a pretty temple dating from the fourth century – when Buddhism was just taking root on the peninsula – making it one of the oldest temples in the country. It was also the venue for the creation of the famed Tripitaka Koreana, eighty-thousand-plus blocks of carved Buddhist doctrine which now reside in Haeinsa temple near Daegu. To reach the temple, take one of the half-hourly buses bound for Onsu-ri. About 5km west of Onsu is Manisan (마니산), the main peak of the island, which affords wonderful views of the surrounding islands. Studding Ganghwado’s east coast are three fortresses – Gwangseongbo (광성보), Deokjinjin (덕지진) and Chojijin (초지진) – which are best seen by making use of the bicycle lanes that run alongside the main road; otherwise, buses run every hour or so. Gwangseongbo (daily 9am–6pm) is the northernmost and most interesting of the three, and dates from the mid-seventeenth century; its strategic importance will be obvious to all visitors, as it peers out over the channel that separates Ganghwado from the mainland.
