Following are links to Strava rides in North Chungcheong Province, and brief descriptions of each course.
Daejeon Lakes: This route around Daejeon is one of the most scenic as it winds its way around the lakes in the area that are created from damned rivers. This route is especially beautiful in April during cherry blossom season; however, during cherry blossom season the roads on the weekends are gridlock, so aim for a weekday during the month of April. The route begins at Daejeon Bus Terminal.
Jecheon Lakes: This route is a pretty tough ride starting and finishing at the bus terminal in Jecheon. It includes a couple steep climbs at the start and lots of small climbs throughout. The scenery is stunning, which is what Jecheon is most famous for.
