One of my favourite places in china, you can spend a week in this area - some of most amazing landscapes of China. Don't miss them!
The reed flute cave is very nice. But one day is probably enough in Guilin (big city).
The best is yet to come! Spend a few days in Yangshuo. This town is equally touristy as beautiful.
It takes 1 or 2 hours to go by bus from Guilin. You can also go by boat, but it is expensive, slow and long from what people told me. You could just take a bamboo raft (1h30) to go down the most beautiful part of the river. That's amazing and much cheaper! It is incredibly beautiful, you will pass the landscapes that are on the 20-yuan banknote!
One of my best memories was to cycle for a day in the countryside towards Dragon Bridge surrounded by the mountains, the fields, the farmers... it is really peaceful, green... Take a good mountain bike! or motorbike for the lazy. ;-)
You can also cycle another day to moon hill, the big banyan tree... not so quiet as you stay on a main road.
Back in Guilin, don't forget to go to Longji for amazing rice terraces in the mountains. I went to the village to the quiet village of Dazhai (where pictures are actually taken), you will meet just a few tourists (mainly chinese) there. It is wonderful to hike through the rice terraces for 1 or 2 days.

my favourite place in China. What a breathtaking views........this place is magical. We cruised down river li for hours and u get to see water bufallos, amazingly green fields, crystal clear water, beautiful hills, people fishing, also lots of them trying to jump on the boat and sell u things.........highlight of my China adventure. Check it out on the net and u will see for yourself, my words do not do it justice...........

An awesome cruise. You see the mountains that you see in Chinese paintings that tower into the sky. Traditional villages along the river. Great if you have an adventurous appetite.

It's been a long time since I was there (1994). Probably it has changed a lot but I enjoyed very much taking a small fisherman boat along the river. Also riding a bicicle around the quiet rice fields.

One of the must-see places of China, one of the most amazing places I have ever visited, unbelievable picturesque landscape scenery, nice people ... would recommend to everyone.
