This park is named for an ancient well whose water is considered ideal for brewing the famous local longjing (Dragon Well) tea. Distinguishing between varieties and grades of tea can be confusing for novices, especially under high pressure from the eager hawkers. It's worth a preliminary trip to the nearby tea museum to bone up on what's what. The highest quality varieties are very expensive, but once you take a sip you will taste the difference. Prices are intentionally high, so be sure to bargain.
