I spend my holidays by the seaside with my family. It was a fun trip, we were walking near the seaside, taking a lot of pictures. It's sad, that the summer is over, I really would liked to go back to the beach and the gorgeous see. Also I was in a summer camp, where I have found lots of new friends and learned a lot from everyone.
