Is 3 weeks enough time for Vietnam?

Yes, 3 weeks gives you proper time in each region without rushing. You can see the main highlights, experience different cultures from north to south, and have buffer days for rest or spontaneous discoveries. Shorter trips feel rushed; longer trips start hitting diminishing returns.

Should I book accommodation in advance?

Book your first 3 nights only, then stay flexible. Vietnam has abundant backpacker accommodation, and booking on arrival gives you better rates and flexibility if you want to extend stays. Only pre-book during Vietnamese New Year (late January/early February).

How much cash should I carry?

Carry $200-300 in small bills for visa-on-arrival, initial expenses, and rural areas with no ATMs. ATMs are common in cities and tourist areas. Notify your bank before travel. Many places accept USD but give change in Vietnamese dong.

Is it safe to eat street food?

Yes, but be smart about it. Choose busy stalls with high turnover, avoid pre-cut fruit, and drink bottled water for the first week while your stomach adjusts. Pho from busy morning stalls is generally very safe. Avoid ice in drinks initially.

Do I need to book tours in advance?

No need to book tours from home. Local booking saves 30-50% and you can read recent reviews. Book Ha Long Bay cruises 1-2 days ahead, other tours can be arranged same-day or next-day through your accommodation.

How to Plan a 3-Week Vietnam Backpacking Route

Start in Ho Chi Minh City, work your way north through the Mekong Delta, central coast (Hoi An, Hue), and finish in Hanoi with a Ha Long Bay trip. Allow 5-7 days in the south, 8-10 days in central Vietnam, and 5-7 days in the north. Book internal flights for long distances and use buses for shorter hops.

Choose your direction. Go south to north (HCMC to Hanoi) or north to south. South to north works better for most travelers because you end with cooler weather in the north and can fly home from Hanoi. North to south works if you want to end with beaches and warmer weather.
Plan your three regions. Allocate 5-7 days for southern Vietnam (Ho Chi Minh City, Mekong Delta, Cu Chi Tunnels), 8-10 days for central Vietnam (Hoi An, Da Nang, Hue, possibly Dalat), and 5-7 days for northern Vietnam (Hanoi, Ha Long Bay, possibly Sapa). This gives you buffer days for travel and rest.
Book your international flights. Fly into Ho Chi Minh City and out of Hanoi (or reverse). Multi-city tickets cost $50-100 more than round-trip but save you a $150-200 internal flight back to your departure city. Book 6-8 weeks ahead for best prices.
Plan internal transport. Book one internal flight: HCMC to Da Nang (or Da Nang to Hanoi) for $60-80. Use buses for everything else. The Sinh Tourist and Hanh Cafe run reliable tourist buses between major stops. Night buses save accommodation costs but are tiring.
Book first 3 nights only. Reserve accommodation for your first 3 nights and leave the rest flexible. Book through Hostelworld or Agoda. Dorm beds cost $8-15, private rooms $20-35. Having your first stop sorted reduces arrival stress.
Plan around weather. Avoid central Vietnam during October-December (heavy rains) and northern Vietnam during December-February (cold and drizzly). March-May and September-November are ideal for most regions. Southern Vietnam is warm year-round.
Get your visa sorted. Most nationalities can get a 30-day e-visa for $25 or visa-on-arrival. Apply for the e-visa 2-3 weeks before travel. If you're staying exactly 21 days, you don't need an extension. Longer trips need a visa extension ($45-60) or exit and re-entry.
