Street food & seafood

Halong Bay offers tourists a wide range of delicious and affordable dishes, combining both Vietnamese and Western cuisine. Cruise dining generally has high hygiene standards, especially mid-range and luxury cruises. However, when eating street food or at local stalls, it’s better to choose clean and busy places to ensure both safety and health.

Tips:

• Avoid raw or undercooked seafood unless you’re certain it comes from a reliable source.
• Wash or sanitize your hands before every meal.
• Watch out for common allergens in Vietnamese cuisine such as fish sauce, peanuts, or shellfish.
• Choose freshly cooked, steaming-hot dishes instead of food that has been sitting out.

• Pro: Authentic culinary experience, diverse flavors, affordable prices.
• Con: Higher risk of stomach upset if food hygiene is not guaranteed.

2. Drinking Water & Hydration

Most mid-range and luxury cruises in Halong Bay offer bottled water daily for guests, and  it is strongly recommended that you rely only on that water for drinking. It’s essential to note that tap water in Halong Bay and surrounding areas is not always safe for direct consumption, as the filtration systems may not meet international standards. Even for brushing teeth, many travelers prefer using bottled water to minimize risks of disease.

Tips:

• Always carry sealed bottled water, especially when leaving the cruise for excursions.
• Drink regularly throughout the day, even if you don’t feel thirsty, to prevent dehydration.
• Avoid ice in street stalls unless you’re certain it’s made from purified water.
• For sensitive stomachs, consider bringing electrolyte packets or oral rehydration salts (ORS).

Eco note: To reduce environmental impact, you should bring a reusable bottle and refill it at cruise or hotel refill stations where available.

To stay safe and enjoy your trip without disturbance, keep these below tips in mind:

Tips:

• Wear protective clothing: Light, long-sleeved shirts and pants can be helpful when spending time on deck at night or during shore excursions.
• Keep your cabin secure: Make sure doors and windows are closed, and use the cabin’s air-conditioning if available. 
• Avoid strong scents: Avoid using perfumes, scented lotions, or heavily sweet fragrances as these scents may attract mosquitos. 
• Consider natural options: Some travelers carry citronella oil, lavender, or mosquito patches, which can be an extra layer of protection.

If bitten: 

• Wash the affected skin gently with soap and clean water to reduce irritation and prevent infection. 
• Apply a soothing cream or an anti-itch lotion (such as aloe vera gel, calamine lotion, or hydrocortisone cream) to relieve discomfort. 
• Avoid scratching too much, as this can worsen the irritation or cause minor infections.
