Southern Vietnam (Ho Chi Minh City): Tropical climate with two seasons – dry (December to April) and wet (May to November). Temperatures remain consistently warm, typically 25 to 35 degrees Celsius.

Getting Around

Domestic Flights

Vietnam Airlines, VietJet Air, and Bamboo Airways operate frequent domestic flights between major cities. The flight from Hanoi to Ho Chi Minh City takes approximately two hours.

Trains

The Reunification Express runs the length of the country from Hanoi to Ho Chi Minh City, stopping at major cities along the way. The full journey takes approximately 30 to 35 hours, but shorter segments (such as Hanoi to Hue or Da Nang to Hoi An) are popular with tourists.

Ride-Hailing and Taxis

Grab is the dominant ride-hailing app in Vietnam and is the easiest way to get around cities. Metered taxis from reputable companies (Vinasun in the south, Mai Linh nationwide) are also reliable. Always confirm that the meter is running or agree on a fare before departing.

Motorbikes

Motorbikes are the primary mode of transportation for most Vietnamese people. Visitors can rent motorbikes, but this is only recommended for experienced riders. Traffic in Vietnamese cities is dense and follows local customs that differ significantly from Western driving norms.

Electricity

Voltage: 220V, 50Hz
Plug types: A and C (two-pin plugs, both flat and round). Most hotels provide universal outlets, but carrying a universal adapter is recommended.

Food and Drink

Vietnamese cuisine is one of the most celebrated in the world, emphasizing fresh herbs, rice, noodles, and a balance of sweet, sour, salty, and spicy flavors. Key dishes to try include pho, banh mi, bun cha, com tam, and fresh spring rolls.

Tap water is not safe to drink. Bottled water is inexpensive and available everywhere.
Ice in restaurants and established cafes is generally safe, as it is produced commercially.
Vietnamese coffee is strong and distinctive, often served with sweetened condensed milk. Egg coffee (ca phe trung) is a Hanoi specialty worth trying.

Health and Safety

Vaccinations: No vaccinations are required for entry, but hepatitis A, hepatitis B, typhoid, and tetanus are recommended by most health authorities.
Travel insurance: Strongly recommended for all visitors.
Safety: Vietnam is generally safe for tourists. Petty theft (bag snatching, pickpocketing) is the most common concern. Keep valuables secure and be cautious in crowded areas.
Emergency numbers: Police 113, Fire 114, Ambulance 115

Additional Practical Tips for Visitors

SIM Cards and Mobile Data

Purchasing a local SIM card is highly recommended for staying connected during your visit. SIM cards from carriers like Viettel, Mobifone, and Vinaphone are available at the airport and throughout cities for approximately $5 to $10 USD, including generous data allowances. Having mobile data makes it easy to use Grab for transportation, Google Maps for navigation, and Google Translate for communication.

Bargaining and Shopping

Bargaining is expected at local markets, street vendors, and some smaller shops. Start at about 50 to 60 percent of the quoted price and negotiate from there. Bargaining is not appropriate in supermarkets, shopping malls, restaurants, or professional establishments like dental clinics. At Serenity International Dental Clinic, all pricing is transparent and fixed.

Cultural Etiquette

Understanding basic Vietnamese customs helps create positive interactions:

Remove shoes before entering someone’s home or a temple
Dress modestly when visiting pagodas, temples, and religious sites (cover shoulders and knees)
Use both hands when giving or receiving items, particularly business cards or gifts, as a sign of respect
Avoid public displays of anger – remaining calm and smiling is valued in Vietnamese culture
Ask permission before photographing local people, particularly in rural areas

Can I use US dollars or other foreign currency in Vietnam?

While some hotels and upscale establishments in tourist areas accept US dollars, the Vietnamese Dong is the official currency and is required for most transactions. ATMs dispensing Vietnamese Dong are widely available, and exchange rates at banks and licensed exchange counters are generally fair. Avoid exchanging money with unofficial street changers, as counterfeit notes can be an issue.

Is Vietnam suitable for elderly travelers or those with mobility issues?

Vietnam is becoming more accessible, though challenges remain. Major international hotels and modern shopping centers generally have elevators and ramp access. However, sidewalks can be uneven, and many older buildings lack elevators. At Serenity International Dental Clinic, our facilities are designed to be accessible and comfortable for patients of all mobility levels. For elderly dental tourists, we recommend staying at a modern hotel near the clinic to minimize travel difficulties.
