I love camping. It’s my favorite way to spent the summer vacation. Last year, my family and I went camping in the countryside. It was one of the most excited experiences I had never had. We slept in a tent and went on a long walk every day. We cook over a fire and the food always tasted wonderfully. For a whole week, I saw lovely mountain views or breathed fresh air. At night, I heard the gentle wind blowing in the tree, and I felt so peaceful. It doesn’t cost many to camp, and what I believe it’s the best way to get close nature and enjoy its beauty.
