1. Rain Tapping on Glass Roofs and Green Comfort: Sejong National Arboretum & Suwon's Irwol Arboretum
Step into a glass greenhouse on a rainy day and the colors of the leaves become far deeper and more vivid than usual. The Four Seasons Exhibition Greenhouse at Sejong National Arboretum, the largest in Korea, connects its tropical, Mediterranean, and special exhibition greenhouses, together covering an area of several soccer fields, entirely indoors, so you can fold your umbrella and stroll among flowers and trees.
In the capital area, the exhibition greenhouse at Suwon's Irwol Arboretum is a great refuge from the rain. Wander the greenhouse among Mediterranean olive trees and the scent of herbs, then sip a warm coffee at the café while watching rain fall on Irwol Reservoir through floor-to-ceiling windows, and a rainy day will feel more like a blessing.

Yeohaenggak editor's tip In Sejong, pairing the National Children's Museum in the morning with the Four Seasons Exhibition Greenhouse at Sejong National Arboretum in the afternoon lets you get through a full day without a single drop of rain on you.
2. The Earth's Inner Depths, Beyond the Reach of Rain and Wind: Danyang's Gosu Cave & Jeju Stone Park
If it rains in Danyang, a destination centered on mountains and valleys, head straight to Gosu Cave. Whether a downpour is raging outside or a heat wave is in full force, the inside of Gosu Cave keeps the stillness and cool temperature it has held for hundreds of millions of years, revealing a mysterious world of stalactites and stalagmites. Following the cave with a bubbling pot of spicy maeuntang (fish stew) at Geujip Ssogari is the best rainy-day treat.
On Jeju Island, where rain and fog are frequent, the Jeju Stone Museum, the large underground exhibition hall of Jeju Stone Park, and the Five Hundred Generals Gallery show their true worth. Walking past the rooftop water feature (Sky Pond), turned into a mirror by pooled rainwater, and the grand underground galleries of volcanic stone, you fall for the weighty aesthetics of Jeju's rainy weather.

Yeohaenggak editor's tip If it rains while you're traveling in western Jeju, Hallim Park, with Hyeopjaegul and Ssangyonggul (lava caves) and indoor greenhouses, is another great rainy-day course.
3. Warm Herbal Foot Baths and Indoor History Hall Tours: Daegu & Gunsan
The joy of a city trip on a rainy day lies in a tight route that runs from museum to museum and on to warm indoor experiences. In Daegu, tour the Daegu Modern History Museum and Daegu National Museum, then shake off the damp mood with a foot bath, soaking your feet in hot herbal water in the indoor experience room of the Daegu Yangnyeongsi Museum of Oriental Medicine.
Gunsan, too, is well stocked with high-quality indoor exhibition halls, including the Gunsan History Hall of the Japanese Colonial Period, the March 1st Movement 100th Anniversary Memorial Hall, and the Geumgang Future Experience Center. After the exhibits, enjoy fresh-baked bread and warm milk tea at the Iseongdang main store to complete the charm of a port city in the rain.

Yeohaenggak editor's tip When it rains during a trip to Busan, too, pairing the Busan Modern & Contemporary History Museum (main building and annex), an indoor cultural complex that revitalized the former Bank of Korea building, with NOTICE, a large warehouse café with a port view, keeps things comfortable.
