White Rock Lake meets our short list of essential criteria for a perfect picnic spot. It's clean and close by, with choice scenery, and hardly anyone ever gets murdered there. White Rock Lake spans 1,873 acres and offers so many interesting venues, it would be tough to get tired of it as a picnic paradise. People fish, feed the ducks, walk, run, bike, sightsee, bird-watch, paddle and sail, enjoying the water, six playgrounds, 11 miles of trails, Dallas' first dog park and historic buildings such as Bath House Cultural Center, created in the 1930s.
