Bariloche is a city in a state called Rio Negro in Patagonia．This city brings me a lot of memories because I went there for my graduation tip from high school．We left in the first week of September．We were a group of 50 students and it was the best trip ever．

We visited different places such as Isla Victoria which you reach by boat，sailing（航行）through the NahuelHuapi Lake．This is a very calm place and worth visiting．We went as well to the Cerro Viejo which has a beautiful restaurant on the top from where you can admire the whole city．We went skiing to Cerro Catedral four days out of ten and it was a great experience．

We visited the LlaoLlao hotel that is pretty different from other hotels．It is in the middle of a group of mountains and it seems as if we were watching a postcard．From there，we went to a farm where we did some horse riding，and we played some games which made us wet and dirty．Finally，some of us went fishing and the rest walked through the forest，We spent that night there camping and the next morning we went on a bus to Cerro Tronador which is the highest mountain in the whole area．It is3478 meters tall and there we visited forests and lakes．During our last day in Bariloche，we went shopping and they offered us all kinds of things．You can buy things such as handmade clothes and shoes．We also visited a chocolate factory and watched the whole process of producing chocolate and selling it．

Visiting Bariloche with my classmates was a great experience．
