Scenic Introduction
Gandel Mountain Fantastic Gorge, also known as "One-Line Sky". Stretching over 250 meters long, it is flanked by towering jagged peaks as if split open by axes and blades. The narrowest section is merely one to two meters wide. About one hundred meters into the gorge, a huge boulder wedges perfectly between the two rock walls, hanging suspended in mid-air. This peculiar sight lends an air of profound mystery to the whole valley.
Located on Gandel Mountain in the northwest of Hainan District lies this stunning gorge, as though a giant blade had sliced the mountain clean in two. The full length of the gorge is 650 meters, measuring 2 to 3 meters wide at the bottom and 5 to 6 meters wide at the top, with stone cliffs rising more than 100 meters on both sides. When walking deep inside and looking upward, the sky is compressed into a thin strip, hence the well-known name "One-Line Sky".
An elderly local herdsman shared: "Many legends surround the formation of One-Line Sky. Some say it was left behind when Erlang God split the mountain to rescue his mother; others claim Immortal He Xiangu carved this passage to make it easier to gather medicinal herbs on the mountain."
In 1994, a group of Chinese geologists gathered here to conduct special research into the gorge’s origins. The experts reached a unanimous conclusion that the One-Line Sky was formed by mountain fractures and displacement triggered by earthquakes. At present, Hainan District has incorporated the gorge into its development plan, aiming to develop this marvelous valley into a formal tourist attraction.
