I think it is cheapest to eat rainbow trout in Huairou, and the taste is almost the same! I'll go to Huairou Mountain. No matter the size, it's 20 yuan a piece. When you get to Shidu, you will find Fangshan. The cheapest price is 25 per catty and golden trout is 30 per catty. Black Dragon Pool should be in Miyun. I went to Miyun Reservoir last time. The farmhouses there were very expensive and the food was not good.

If you go to Miyun, go to the Herb Botanical Garden. There will be lavender in bloom in July, which is called Little Provence!
