Very good, beyond expectations, the first half of the fir river rafting is gentle, you can enjoy the scenery on both sides of the Straits, drifting in the Grand Canyon, giving people a sense of Jurassic world jungle adventure. The second half is more exciting, and dopamine rises in a straight line. At night to the county at night drifting, relatively gentle, you can watch the lights on both sides of the Straits.
