There's nothing like relaxing by the water while you're on vacation. Bring a picnic to Heaven Lake and then stick around for an impressive sunset.
You'll soon see why this Baishan body of water is a hit with travelers. If you're searching for more to do and see here, Changbai Shan Nature Reserve, Changbaishan Tianchi, and Changbai Mountain Museum are in this area too. They won't take very long to reach from Heaven Lake.
