What to do?
Most of Quang Binh Province is lined with sand dunes and beaches in which Da Nhay and Ly Hoa Beach (60 km north of the city) are the most popular tourist destinations. However, the main attraction of Dong Hoi is a trip to the Phong Nha Cave, a spectacular cave was used by the Northern Vietnamese as a field hospital during the war and declared as a World Heritage Site by the Unesco in 2000.
When to go?
In Dong Hoi, the spring is cool, humid and foggy with the average temperature from18 to 25 degrees Celsius. The summer sees the hot, dry weather with the temperature may be as high as 35 degrees Celsius. It is rainy in the fall but the weather is comfortable with the temperature around 25 to 30 degrees Celsius. In the winter, it may be rainy and the temperature may go down to 12 degrees Celsius.
The best time to visit Quang Binh and Phong Nha Caves is the dry season, between February and April when the weather is cool and there is no flooding.
Travelers should check carefully the weather in this area during November and December before travel as during this period, the river is prone to flooding; the underground cave may be close. Though it’s possible, but also may be dangerous to visit the dry cave.
