🇹🇭Thailand, Hin Sam Wan Rock (Three Whales Rock) 

The futuristic mystery of nature Hin Sam Wan from Bueng Kan province, Thailand is the "Stone of Three Whales" that majestically "swim out" of the mountains.
The rocks were formed 75 million years ago and create the illusion of a family of whales swimming in the middle of the forest. And for fans of Ridley Scott's early films, they are more likely to resemble alien xenomorphs from the Alien film series.

Only two rocks ("mother whale" and "father whale") can be reached on foot, it is impossible to reach the "baby whale" by land.

This place is not very popular. Moreover, relatively recently, images from space have shown that there are several more such natural “structures” in the jungle, the existence of which even the locals did not know. According to geologists, the rocks assumed an unusually smooth and rounded shape due to the centuries-old influence of tropical winds and heavy rains.
