Introduction to Crocodile Pool: This pool is naturally formed. Because the stone pressed under the cliff on the west bank of the pool is shaped like a crocodile's head, it is named Crocodile Pool. It is said that the crocodile wanted to block the river, so it was alarmed. He invited all the immortals to come to the mortal world and enchanted the crocodile under the stone. To this day, it is difficult for him to turn over.
