Kaudulla National Park is a place where lots of special plants and animals live in a big area protected by the government. It's kind of like a big playground for the animals, where they can run around and play without being bothered by people who might want to hunt or hurt them.
One really cool thing about Kaudulla National Park is that it's home to lots of elephants! These elephants are very big and live in groups called herds. They like to eat leaves and branches from trees, and they drink water from rivers and ponds. The park also has other animals like deer, monkeys, and lots of different types of birds.
People can go visit Kaudulla National Park to see all these animals and learn about them from special guides who know a lot about the park. But it's very important that visitors don't disturb the animals or leave anything behind that might hurt them, because we want to keep the park safe and healthy for everyone who lives there.
