Reviews
I participated in a nature guided tour. It was a pleasant experience just to take a walk in the beautiful natural environment, and the guide staff explained a lot of trivia to us, so we were able to learn about the beauty of nature and how it came to be.

It was an experience that reminded me of the importance of protecting the environment and how magnificent nature is.
This time we stayed in a room for five people, and the room was spacious! We also had a lake view in front of us and enjoyed the beautiful view with stars at night and sunrise in the morning. The staff was very kind and we had a warm and comfortable stay. We will stay there again. Thank you very much!
