My first visit to Nha Trang, the coastal city, was three years ago. It was a pleasant and memorable trip.

Nha trang, the capital of Khanh Hoa province, has one of the most popular municipal beaches in all of Viet nam. In Nha Trang, nature beauties are so tempting. Waves crashing onto the cliffs, the soft sigh of the sea breeze, clean white sands and turquoise waters, it all makes for a stunning landscape. On my visit to Nha Trang, I used to get up early each morning to stroll along the beach - a chance to breath in the fresh sea air and enjoy the sunrise across the water. One attraction that captivated me three years ago and still it does is the collection of small offshore islands, that is Hon Tre where is the largest of the islands.

Nha Trang is the city in hamoney, its fine wather, favorite position and friendly people bring it a certain balance. Nha Trang is a great holiday destination. I hope to have chance to come back
