The classic route through Vietnam runs via Ha Long, Hue and Hoi An. This one chooses another face of the centre. First comes Phong Nha–Ke Bang National Park, whose limestone mountains hide some of the largest caves in the world: you enter them by river boat, on wooden walkways or by kayak. Evenings are for cycling between rice fields and a simple dinner by the river.

The second half is a coast without crowds. After a short stop in Da Nang, the journey continues south to Quy Nhon, a city where the beaches still belong to fishermen and thousand-year-old Cham towers stand on the hills. The route suits families with children who like to be active, and couples who want to balance adventure with rest in comfortable stays by the sea. The pace, the activities (matched to children's ages) and the stays would be shaped around you.

The route

The journey

  1. Dong Hoi
  2. Phong Nha–Ke Bang
  3. Da Nang
  4. Quy Nhon
  1. A river curving past a village and fields between green limestone hills

    01Days 1–2 · Phong Nha village

    Arriving among the limestone hills

    From Lithuania you fly via European and Asian hubs to Hanoi or Ho Chi Minh City, then take a short flight to Dong Hoi. Less than an hour's drive brings you to Phong Nha village on the Son river. The first days are slow: cycling between rice fields and buffalo pastures, a swim in the river and a first evening on a terrace as mist rises over the hills.

  2. Emerald water beneath a wide cave mouth, with small figures of visitors on the bank

    02Days 3–4 · Phong Nha & the Dark Cave

    By river into the mountain

    A wooden boat carries you up the Son river to Phong Nha cave, and the engine falls silent as you are paddled into the underground river between the stalactites. The next day is more active: kayaking on the Chay river, and for the braver a zipline and a headtorch walk into the Dark Cave, where a mud bath awaits. Age and height limits apply, so younger children would have gentler trails and a swim in the Nuoc Mooc streams instead.

  3. Softly lit stalagmites and calcite walls in a great limestone cave chamber

    03Day 5 · Paradise Cave

    An underground cathedral

    Paradise Cave is one of the park's most striking: after climbing hundreds of steps to the entrance, a boardwalk of about a kilometre leads through vast chambers of stalagmites and calcite curtains. Those who want more could join a day or overnight trek into wild caves with a licensed guide. The famous Son Doong cave is also in this park, but it can only be reached on small, permit-limited expeditions; that is a separate journey, not part of this route.

  4. The rocks of the Marble Mountains rising above the rooftops, Da Nang

    04Days 6–7 · Da Nang

    A pause by the sea

    By train, or by road via Hue, to Da Nang. Two quiet evenings by the city's long beach, a morning among the cave shrines of the Marble Mountains, and the forests of the Son Tra peninsula, where with luck you may spot the rare douc langurs. If you'd like to see Hoi An, go early in the morning while the old town is still empty, then return to the sea.

  5. A long sandy beach with round fishing coracles beneath a mountainous headland

    05Days 8–11 · Quy Nhon

    A coast that still belongs to fishermen

    The coastal train heads south, several hours past rice fields, lagoons and hills, to Quy Nhon, where you stay in a quiet hotel by the sea outside town. The days are slow: swimming, round fishing coracles on the beach at dawn, a boat to the clear water of Ky Co bay and a coastal path along the rocks of Eo Gio. Evenings mean seafood and prawn banh xeo in simple local eateries.

  6. Fishing and day boats in the bay off Nhon Hai island, Quy Nhon

    06Days 12–13 · Nhon Hai & the Cham towers

    Thousand-year-old towers above the sea

    The final days are for history and fishing villages. Around Quy Nhon stand the brick towers of the Champa kingdom: the Twin Towers in the city itself and the Banh It towers on a hill overlooking rice fields and the river. A boat can take you to the fishing villages of Nhon Hai and Nhon Ly, where nets dry along the shore. You depart via Phu Cat airport, with flights to Ho Chi Minh City or Hanoi.

First, we listen. Then, we explore what's possible.

Make it your own

  • With younger children

    Fewer steps and more water: Phong Nha cave by boat, swimming in the streams and longer by the sea instead of the Dark Cave.

  • A caving adventure

    Adults and teenagers could add a night camping in a wild cave with a licensed guide: physically demanding, with limited places.

  • With Hue

    On the way to Da Nang, spend two nights in Hue, the imperial city of the citadel and royal tombs along the Perfume River.

  • More rest at the end

    Add a few more days at a hotel by the sea in Quy Nhon, or continue to the islands of the south.

Practical considerations

  • The Phong Nha caves are usually best visited from around February to August; in autumn (roughly October–December) rain and flooding close some caves and trails.
  • On the central coast, swimming is most pleasant in spring and summer, while storms and tropical downpours are possible from autumn; midsummer can be very hot.
  • Active cave excursions have age, height and health requirements; we'd check these for everyone travelling, and it's worth asking a doctor about children's health on the road.
  • Trains along the central coast are comfortable but not fast, so transfer days are planned without rushing.

General guidance only. Seasons, weather and wildlife are never guaranteed, and travel requirements are always worth checking before you go.
