Planning a 3 weeks Vietnam itinerary is the perfect way to experience the country in depth, from north to south. Vietnam stretches over 1,600 kilometers, and within that distance lies a captivating blend of ancient culture, stunning natural landscapes, vibrant cities, and timeless rural traditions. With 21 days to travel, you can take your time to fully absorb the diversity of each region instead of rushing from one highlight to another. This Vietnam travel guide introduces a carefully curated journey designed to showcase the country’s most iconic landmarks as well as hidden gems. Begin in Hanoi, the thousand-year-old capital where colonial charm meets traditional temples, then cycle through Duong Lam Ancient Village and trek the rice terraces of Pu Luong Nature Reserve. Cruise overnight through the emerald waters of Halong Bay, before venturing to Phong Nha–Ke Bang National Park for an adventurous cave expedition. The central region offers the imperial grandeur of Hue, the lantern-lit charm of Hoi An, and the mystical ruins of My Son Sanctuary. Continue to the dynamic south with Saigon’s historic landmarks, the wartime history of Cu Chi Tunnels, and finally the waterways of the Mekong Delta with its floating markets and bird sanctuaries. This 21-day Vietnam itinerary is the ultimate way to explore the country at a comfortable pace, blending culture, adventure, and authentic local encounters.
