On the 4th day, we went rock-climbing. The rock-climbing was really challenging but exciting. We went by bus to the rock-climbing place. There were 5 courses and there was the easiest one to the hardest one. I did the third hardest one. We put on helmets and life belts so that it will be ok even we put our hands off the rock or lose balance. I did rock-climbing before but it wasn’t that big. This one was huge!! When I got to 6m, my hands hurt so I couldn’t go to the top. Some of the people went to the top on the one I did, and harder ones. They were really cool. I watched other people do it and talked with my friends. After everyone had more than a turn, we went back to our hotel. Rock-climbing was harder than I thought was really fun. I want to rock-climb again and try to go to the top.
