Gangchon Rail Park

When the Gyeongchun line to Chuncheon was rerouted and electrified in 2010, a stretch of the old single track was left in place, and rail bikes were put on it. You pedal a four-wheeled cart - two or four seats, with an electric assist on the climbs - about eight kilometres from Gimyujeong station along the Bukhangang, over an iron bridge, through several tunnels lit with coloured installations and music, to Gangchon, where a converted train carries you and the bikes back. The riding is easy and mostly flat; the tunnels are the part people remember, and the river scenery is genuinely good in autumn. The starting station is named after the writer Kim Yu-jeong, who was born in the village, and there is a small literary village nearby. Slots sell out at weekends and in peak autumn, so booking matters.

What you'll find

• The old single track - eight kilometres of the disused line.
• The lit tunnels - coloured installations and music inside.
• The Bukhangang - the river and the iron bridge crossing.
• The return train - the converted service back from Gangchon.

When to go

April to June and September to November; autumn colour along the river is the peak and books out. Weekdays are easier. It runs in light rain but not in storms.

What to expect

Ticketed and time-slotted - turning up without a booking at a weekend usually fails. It is a leisure ride, not transport, and the pedalling is easy to the point of being undemanding. Riders sit exposed to the weather.
