Thirty days is genuinely comfortable pacing for Vietnam: room for the two mountain regions in the north, the full length of the country, and slow island time at the end, with rest days built in rather than added as an afterthought. No single month suits every region equally, so the route below states the months each leg actually wants. For the shorter version this builds on, see the 3-week Vietnam itinerary; for the full range of lengths, see the Vietnam itinerary guide.

This route rides the Ha Giang Loop and treks around Sapa as two separate legs with a rest day in Hanoi between them, since the two mountain regions don't sit on the same road. If you want a second island, budget an extra 3 or 4 days for a separate flight to Con Dao rather than assuming it connects easily to Phu Quoc. Cavers with a fixed month should ask a licensed operator about a multi-day Son Doong or Tu Lan expedition out of Phong Nha, but book as early as you can: Oxalis lists its 2027 and 2028 Son Doong seasons as fully booked, and the expedition runs only from January to August.

Choosing between them

Choose...If...
The full route (the loop and Sapa both)You want everything the country offers and don't mind two separate mountain legs
The centre and south, slowerYou'd rather skip the far north's cold and the motorbike risk, and like the idea of continuing into Cambodia
The centre in depthCaving is the priority and you're planning a Son Doong or Tu Lan trip well ahead

Costs, best time and getting around

Outside international flights, budget about US$35 to 45 a day for a month in Vietnam, including a dorm bed or homestay. The Ha Giang Loop adds a 4-day easy-rider tour at about US$190 to $240 at budget operators (some quote US$280 or more), and Phu Quoc and Con Dao both cost more than the mainland once flights and beach accommodation are added. No single month suits every region, since the north's cool season, the centre's dry season and the south's dry season don't fully overlap. The far north is coldest and foggiest from December to February and wet, with landslide risk on the mountain roads, from May to September. The Ha Giang Loop is best in October and November, with March and April a good shoulder season. The centre gets heavy rain from about mid-September to December, with floods most likely in October and November, and is driest from February to May. The south's wet season runs from about May to November (May to October on Phu Quoc). March to April is the best compromise across all of them. See best time to visit Vietnam for the month-by-month detail. A Vietnam e-visa runs up to 90 days, well inside a month-long trip for most nationalities; see the Vietnam visa guide for your passport.
