In KOREA, there are several rail bike attractions.
The farthest rail bike is SAMCHEOK RAIL BIKE at EAST SEA.
The second farthest one is JEONGSEON RAIL BIKE, which shows the real deep mountain scenery.
But, most tourists staying at SEOUL choose GANGCHON RAIL BIKE nearby NAMI ISLAND.
GANGCHON RAIL BIKE has two trails, which are 1) GANGCHON RAIL BIKE and 2) GYEONGGANG RAIL BIKE. You can choose either one.
GANGCHON RAIL BIKE is the one-way route and you need to get on the (engine) train for the last-half of the journey.
Whereas GYEONGGANG RAIL BIKE is the round-trip journey by 100% man-power. But, the built-in motor of each bike pushes the bike from behind while you are coming up the path.
Our company prefers GYEONGGANG RAIL BIKE to GANGCHON RAIL BIKE because GYEONGGANG RAIL BIKE’s 1) scenery is similar, 2) price is cheaper, and 3) less crowded.
