Đồng Mô Tourism Area
Located 22 miles (35 kilometers) from the center of Hanoi, Đồng Mô tourism area is popular among Vietnamese locals for a weekend away from bustling city life, especially Son Tin Camp. Surrounding the area are verdant hills, endless forest and a clear lake, making it an ideal place to lace up your hiking boots. Since it is a popular retreat you will have access to additional activities set up by enterprising outdoors folk, including zip lining and paddle-boating.
Cúc Phương National Park is the biggest national park in the north of Vietnam, spreading over three provinces with the majority set in Ninh Binh (famous for its spectacular karst topography). If Ninh Binh is on your Vietnam itinerary, then spending a couple of days here is ideal. Nature and adventure lovers will be rewarded with spectacular scenery including lush mountains, photogenic rivers, underground caves and a diverse ecosystem. Head over during northern Vietnam’s dry season (which spans from December to May), when the forest is less humid and temperatures more pleasant. April and May are when the butterflies are in full bloom. Cúc Phương National Park is protected by the local authorities, so do call in advance.
