청초호 is a curated attraction in Korea — full details, hours, and access info on the official Korea Tourism page.
Cheongchoho Lake is a coastal lagoon in Sokcho, Gangwon-do, with a long lakeside walking and cycling circuit, mountain views toward Seoraksan, and direct integration with central Sokcho. The lake is one of two famous lagoons in Sokcho (the other being Yeongnangho) — both formed by the Korean East Sea coastal geomorphology where lagoons sit just inland of beach barriers. For travelers based in Sokcho and wanting a low-pressure outdoor anchor that captures the area's coastal-lagoon character, Cheongchoho is one of the cleaner single picks. Best as a half-day lakeside walk combined with central Sokcho dining.
