Make ARTE Museum the fixed indoor visit, then decide on a second stop after checking the weather. This keeps a rainy-day plan centred around Gyeongpo and Chodang instead of spending the day crossing Gangneung to replace each cancelled outdoor activity.
Set the day around ARTE Museum
ARTE Museum Valley Gangneung is at 131 Nanseolheon-ro beside Gyeongpo Lake. Its visitor listing gives daily hours of 10:00–20:00, with last admission at 19:00. Listed exhibition admission is ₩19,000 for adults, ₩15,000 for teenagers, ₩12,000 for children and ₩10,000 for preschoolers; infants enter free. Check the museum’s visitor details for current ticket terms before travelling.
Keep lunch in the Gyeongpo–Chodang area. Ojukheon is a separate outdoor heritage stop: add it only if the rain eases, and allow for exposed courtyards and paths. The picture above shows Ojukheon House, not an indoor rainy-day attraction.
Decide whether a second stop fits
Before leaving the museum, check the conditions and your return connection. Confirm a local bus or taxi towards your base or Gangneung Station; if you have luggage or a train to catch, head back rather than extending the route. Use the Gangneung day plan for the wider rail-return sequence.
