My favorite season is summer. Because my birthday is in summer. And I like to go to the beach because I like swimming.
Activities that I can do in summer are swimming, hiking(of course in winter, spring, fall too.), riding a bike, eating ice cream(of course in winter, spring, fall too.), etc.
I feel good when I'm swimming. And I like hiking too. I went to Dobong Mountain, and Acha Mountain, etc. (In Korea, you can speak like this: Dobongsan, Achasan.) Ilove riding a bike at least it is so cold. And I love eating ice cream, too. It is sweet and delicious.
So my favorite season is summer, and activities that I can do in summer are swimming, hiking, riding a bike, eating ice cream, etc.
