Green Tea Straight from the Source and a Scamper through  Streams
Longjing Village is everything you'd hope to find in search of an authentic Chinese tea drinking experience - your cup of tea will likely have been produced within a few hundred meters of consumption. In addition to striking the gold of Longjing green tea production, there is also a fantastic hike through the tea plantations themselves. Know as 9 Streams and 18 Gullies, this walk not only brings you through the enchanted land of tea - it leads you scampering through a stream, 9 times over. And if you head out on a warm summer day, you may not want to leave.
While it's definitely a tourist destination, the demographic is mostly Chinese - so as a non-Chinese-character reading traveler, finding clear information regarding the area was difficult. But here I am, to lay it out for you.
You can get yourself to Longjing Village easily enough, via taxi or bus (your hotel or guesthouse will be able to advise on the proper bus). If you do take a taxi, your driver will most likely drop you at the entrance to the village (but up the hill from the village proper), which is marked with a large Chinese arch. From there you head down the hill and straight into the village (passing Longjing Imperial Tea House on your way - a gorgeous garden surrounded with hills full of tea). Continue on Longjing Road - at the end of which, you'll find the trailhead to 9 Streams and 18 Gullies.
