The invention relates to a gravity control water curtain generation type sightseeing channel. The sightseeing channel comprises a walkway, an arc-shaped dome is arranged over the walkway, through holes are evenly formed in the walkway, a step plate is arranged in each through hole in a matched mode, each step plate can move up and down in the corresponding through hole, an intermediate plate is fixedly arranged below each step plate, a compression spring is arranged between each step plate and the corresponding intermediate plate, an upper inserted bar is fixed to the center of the lower end face of each step plate, the lower end of each upper inserted bar penetrates through the corresponding intermediate plate, a base plate is fixedly arranged below each intermediate plate, each base plate is provided with a side slide rack, each side slide rack comprises a side slide plate, and rolling wheels are arranged between each side slide plate and the corresponding base plate. According to the gravity control water curtain generation type sightseeing channel, high pressure water jetting equipment is utilized for jetting water flow to the dome, due to the fact that the dome is in an arc shape, water does not splash when being jetted to the camber surface but rolls down along the dome, therefore visitors inside the sightseeing channel cannot be threatened or influenced, great impact force is generated for visual sense, auditory sense and stereo perception, and the visitors can generate certain excitement and nervous sense.
