If you are looking for a cool summer get-away, be sure to check out some of Korea's splendid valleys. The fresh, leafy groves and icy streams rushing down from the mountains will surely help you beat the heat. There are a great deal of things to do, such as camping, fishing, and even extreme sports such as wake-boarding. History buffs can satisfy their curiosity by learning about events in the valley in times long ago. One of the most eminent Confucian scholars of the Joseon Dynasty, Lee Hwang (이황), spent 9 months in the Seonyudong Valley (선유동계곡) and gave names to all his favorite places. If you venture to Mureung Valley (무릉계곡), you can visit the famous 5,000-meter sq. Mureung Rock (무릉반석), which bears the inscribed names and works of the 'Arcadia' scholars and poets. If you enjoy trekking, check out Deokyusan National Park (덕유산국립공원). The trail goes from Baekryeonsa Temple (백련사) and is a 3-hour round-trip hike for the 6 km trail. Although it's a mountain trail, it's not that steep, making it ideal for trekking.
