Okay, so imagine you are on a really big adventure in a place called Bulgaria. Bulgaria is a country far, far away from where you live. There is this really cool place in Bulgaria called the Bulgarka Nature Park.
In this park, there is a lot of beautiful nature - this means trees, flowers, and animals that you might see in books or in the zoo. Also, there are some really big mountains that you can climb. These mountains are so tall that you might get tired if you try to climb them all at once.
The Bulgarka Nature Park is a very special place because it is important for making sure the trees and animals stay safe and healthy. This park is a bit like your own room or your house, where your parents try to keep everything nice and clean. The people of Bulgaria also try to keep the park clean and safe, so that visitors like you can enjoy it without worrying.
One really cool part of the park is that it has some ancient history. This means that people, like your great-great-grandparents, used to live in the park a long, long time ago. There are some special rocks and caves where the people used to leave messages and drawings on the walls. These messages and drawings help us learn about what life used to be like for the people who lived in the park a long time ago.
Overall, the Bulgarka Nature Park is a really cool place to go to see animals, climb mountains, and learn about history. It is important for people to take care of it so that you and your friends can go on an adventure there.
