The story: Erhai is a high-altitude freshwater lake shaped like an ear — "er" means ear in Chinese — sitting at 1,972 m between Dali Old Town and the Cangshan Mountains. For centuries it was the economic lifeline of the Dali Kingdom, feeding fishing villages and trading towns along its shore.
Why it's a must-see: The classic Dali experience is to rent an e-bike or join a car and trace the lakeshore, stopping at fishing villages, cafés, and viewpoints. Sunrise from the east shore (Caicun) is spectacular, and the water turns from silver to deep blue as the day warms up.
💡 Kat's tip: The full loop is 130 km — doable by e-bike in one long day if the battery is good, but most people split it. Check your rental's range. The west side near the old town gets crowded; the east side is quieter and better for sunrise.
