Meet your guide at 07:00 and set off for a full day exploring Cheorwan. Head north from Seoul, with your first stop at Sambuyeon Falls to admire the stunning 20-metre high waterfall. Continue to Sundam Maeul, the starting point for a 2-hour trek along the Hantan River Geopark, where you'll see unique rock formations, including basalt cliffs and gorges, shaped by volcanic lava remnants. After the trek, enjoy a Korean lunch at Goseokjeong Pavilion.
Then take a boat trip on the Hantangang River to admire the beautiful cliffs and landscapes from the water. Before returning to Seoul, visit Dongsong Market, a traditional market with a variety of stalls and vendors. Explore the regional cuisine and local culture, and consider picking up a souvenir. Transfer back to your Seoul hotel in the late afternoon.
