No, they are not the same.

Li River boat trip is an about 4-hour journey, you will go with an air-con ship with 60-80 passengers, which is comfortable and easy, and lunch is included. The scenery along Li River is amazing. But in the winter, when the water level is very low, it will take more time to stay in the ship, which is kind of boring.

Yulong River is a tribute of Li River flowing through the countryside of Yangshuo, the scenery is exceptional. You will sit in the bamboo-made deck chair attached to the bamboo raft, which is a very unique and pleasant way of sightseeing. It’s no doubt that it is more fun for those soft adventurous travelers to do it, you can even try how to row the bamboo raft by yourself! During the rainy season, when there is a flood, we don't recommend the travelers to do the rafting.
