Dear Megan, Im so happy to know that you are coming to Vietnam for your vacation. When youre here, you should visit Hạ Long Bay. It is in the north of Vietnam and one of the UNESCO World Heritage Sites. Hạ Long Bay is special because it has over 1600 limestone islands with wonderful ocean views. You can take an overnight cruise trip or go kayaking there. Another place you shouldnt miss visiting is Sơn Đoòng Cave one of the most famous caves in the world. It is really big and it has its own river and a forest inside like a fantasy world. You can also go on a trek tour around Phong Nha Kẻ Bàng National Park. This place is home to tigers, elephants and 300 species of birds. The best time to go is from October to December, when the weather is really nice. See you soon, Nhung 33.
