Last summer, I went to Nha Trang beach with my family , it was such a memorable summer holiday. We went there by car , and when we nearly got there, from the far distance , I could see how wide and beautiful the beach was. The weather was so nice that made me want to run directly to the beach, enjoy the fresh air and clean water. There were a lot of people swimming , sunbathing, playing volleyball on the shore , and some children even built sand castles and flew kites .We stayed at Edele hotel whose service I found very satisfied and I had the chance to eat the sea food there , they were very delicious . I went to Vinpearl Land , Long Sơn pagoda,too .They were very wonderful. I felt very fun and happy because I also met many foreigners ,they were tourists and I had talked to them a lot . We stayed in Nha Trang for a week and the last day , I went to some gift shop near the beach to buy souvenir for my grandparents and my friends . When I came back home , I felt very happy but a little regretted because I wanted to stay there longer. I told my dad I liked Nha Trang and I hoped we can go to Nha Trang again one summer .

Weather is always hot in summers , that is why many people choose to escape the heat by going to somewhere cold such as Da Lat or Sapa . And lucky for me , last summer I had had a great chance to go to Da Lat with my friends on my summer holiday. To me , the weather there was so perfect , it was still always cold during that summer . The atmosphere there was very clean and fresh ,which made me feel very comfortable.  Which made me surprised most is that the hotel we stayed has no air-conditional , but we still felt cold ,that’s awesome . We stayed there for about 2 weeks and we had gone to many spectacular places . We went to Love valley- one of the greatest tourists attraction in Da Lat, Elephant falls , Lang Biang , Dambri waterfall, …. I also had chance to try out various food , drink, and fresh fruit . I really liked the mulberry smoothy there ,  avocado ice cream , fruit jam which was made totally from real fresh fruit ,....They were all very tasty . Especially , Da Lat had a number of beautiful scenery,many lovely coffee shop and attractive spots that made me want to take a lot of picture to keep the memory. There was also a night market ,always crowded with customers , where people can buy food , flowers , or any stuff they want. I had went there and buy many gifts for my family . It was an unforgettable trip , I was quite upset that I could not stay there for a long time , but I hoped I still can visit Da Lat whenever I have time , and I really recommend you went to Da Lat for holiday , it is very wonderful !!
