We began exploring the wonders of 2 countries on our
3-week combined
Cambodia Vietnam tour in Siem Reap, where the atmosphere instantly captivated us: gentle warmth, the scent of incense, and kind, welcoming smiles. We kicked things off beautifully with visits to Angkor Thom,
Ta Prohm, and of course, the majestic
Angkor Wat, which we explored by bike. Watching our children ride through these thousand-year-old ruins, eyes wide with wonder, was pure joy. There was a mystical energy in the air, amplified by the giant tree roots embracing the ancient stones.

The peaceful atmosphere of the Buddhist temples in the Roluos group brought us a deep sense of calm during our 21-day Cambodia Vietnam itinerary. These less touristy sites allowed us to truly feel the spiritual essence of the place. The hike to Kbal Spean, through the lush jungle, was another wonderful surprise. At first, our children were a bit grumpy, but they soon ran ahead, captivated by the ancient carvings in the riverbed and the sounds of the forest. Continuing our 3-week Cambodia Vietnam tour, the Banteay Srei temple left us utterly amazed. Its incredibly fine carvings, etched into pink sandstone, rendered us speechless with their delicate beauty and exceptional craftsmanship.
During our combined
Cambodia Vietnam tour, the boat ride on
Tonlé Sap lake, winding through the floating villages, was one of those timeless moments. The striking contrast between the simplicity of local life and the raw beauty of the landscape deeply moved us and invited quiet reflection.
The atmosphere of
Phnom Penh surprised us with its vibrant energy and stark contrast to the previous days: more urban, more steeped in history. The Royal Palace, the Silver Pagoda, and the colorful markets,
top things to do in Phnom Penh, immersed us in a completely different side of Cambodia.
Vietnam welcomed us in
Ho Chi Minh City, bubbling with life and history. The energy there was tangible, vibrant. Our children loved the organized chaos of the traffic, and we savored our first bowl of phở on a terrace, just like the locals. Continuing our
21-day Cambodia Vietnam trip, we boarded the
Bassac cruise in the Mekong Delta, and it was magical! Spending a night on a traditional boat, rocked by the gentle lapping of the river, and waking up in the heart of this floating world was one of the highlights of our journey.
Cai Rang floating market amazed us: boats overflowing with fruits, lively exchanges echoing through the air, it was vibrant, authentic, unforgettable.

After a short flight to
Hoi An, the charm worked its magic instantly. This town is a true gem! We loved the bike ride to
Tra Que vegetable village, where our children got their hands dirty in the fields, laughing out loud. The dinner with a local family remains a precious memory, warm hospitality, delicious homemade dishes, and heartfelt exchanges that went beyond words.
3 week Cambodia Vietnam trip, we then headed to Hue, with its imperial relics and lush landscapes. Visiting Thuy Bieu village brought us closer to the simple and generous rural life of Vietnam.
Northern Vietnam marked the final stage of our
3-week Cambodia Vietnam itinerary, starting with
Hanoi capital, a vibrant, contrasting city full of charm. Its Old Quarter, peaceful lakes, and street vendors created a unique atmosphere. We strolled through the lively streets, tasted local specialties, and fully soaked in the distinctive spirit of the city.
Ninh Binh, or "Halong Bay on land" took our breath away with its dramatic karst formations rising from lush rice fields. The sampan boat ride was poetic, almost surreal. And what about the
Halong Bay cruise? Spending a night on a traditional junk boat, gliding between limestone islets at sunrise... it's an image forever etched in my memory.
This 21-day Cambodia and Vietnam trip was more than just an exploration of new places. It brought us closer together, recharged our spirits, and filled us with wonder. Our children still talk about the temples, the floating markets, the buffaloes in the rice fields, and the many warm smiles they encountered along the way.
