After walking for about an hour, I came to the top of the mountain. There is a cactus botanical garden on the top of the mountain. Ticket price: 4€, free under 11 years old. The mountaintop is full of sunshine and is a good place to take pictures. The cactus is rich in variety and the shape is beautiful. You can see the beautiful scenery of the whole mountain from the top floor. It is great. After reading it, you can only return the same way, there is no other exit~
