It's worth it. You have to rent Jeep's four-wheeler to go up the hill. It's like going up to the top of the observatory in the sky. Surrounding the surface like the moon, driving this dangerous section of stone road, very narrow, two cars facing each other carefully. When passing through the clouds in the middle, you can't see anything. Visibility is too low and you have to climb carefully. Driving feeling is very strong. The air on the observatory is thin, cold and windy, so you can't run fast at the highest altitude. The world's largest astronomical telescope is like an unforgettable experience in outer space. But some of the top photos were stolen from another cell phone.
