Last holiday. I went to climb the Tanggamus Mountain in Lampung. I have never climbed it before. I went there with some of my friends. We started climbing at 7 p.m. It was so dark but I felt no worried because all of my friends were professional climbers.We climbed slowly and enjoyed the moment. After climbing for about 7 hours, we could reach the top of the mountain. There were a lot of other climbers who reached that top faster than us. We waited for the rising sun while cooking some food and drinking coffee to get warmer. Others sang some songs together, shared stories or lay on the ground to take a rest. After seeing the sun rose, we prepared to set up the tent because we wanted to stay there for three days. We really enjoyed the moment and did so many interesting activities there.
After all, that was my greatest experience I have ever had in my life. It was really tiring but I was very happy.
