Best Things to Do in Ha Long in January

Enjoy a Peaceful Overnight Cruise

January is the perfect time to experience an overnight cruise in Ha Long Bay, thanks to the calm seas and cool weather. With fewer tourists around, you’ll enjoy a more intimate and tranquil atmosphere while gliding through mist-covered limestone islands.

Relax at a Seaside Resort or Spa

Events/Festivals In Ha Long In January

Tet Holiday (Vietnamese Lunar New Year)

Tet is Vietnam’s most important and widely celebrated holiday. When it falls in late January, Ha Long becomes vibrant with colorful decorations, red lanterns, blooming peach blossoms, and festive music. Travelers can witness cultural performances at 30/10 Square or along the Bai Chay promenade, enjoy fireworks, and explore Tet markets selling traditional foods and lucky charms. Many cruises and hotels also host unique Tet experiences such as lucky money gifting, making bánh chưng (traditional sticky rice cakes), and New Year’s Eve feasts. Visiting Ha Long during Tet offers a rare cultural experience in a magical, misty coastal setting.

Ha Long Winter Carnival

Although not held annually, the Winter Carnaval is a smaller version of Ha Long’s famous summer carnival and often takes place in late January or early February. Hosted at venues like Sun World Ha Long Complex or the Bai Chay waterfront, the event features parades, street performances, light shows, and food stalls. If the Winter Carnaval coincides with Tet, it often includes traditional dance, music, and lion dances, creating a festive blend of modern and cultural vibes.

Yen Tu Spring Festival (early preparation starts late January)

Held at Yen Tu Mountain, about 50–60 km from Ha Long, this is one of Northern Vietnam’s largest Buddhist festivals. While the main event falls on the 10th day of the Lunar New Year (usually in February), pilgrims begin arriving as early as late January. Visitors hike through misty mountain trails, visit ancient temples, and climb to Dong Pagoda at the peak to pray for luck and peace in the new year. The combination of spiritual tradition and breathtaking natural beauty makes Yen Tu an unforgettable cultural day trip from Ha Long.

Tips for Traveling to Ha Long in January

Book Tours and Cruises in Advance

While January is not peak season, it still draws many international travelers thanks to the cool, dry weather. If your trip overlaps with Vietnamese Lunar New Year (Tet), accommodations and cruise slots may fill up quickly. It’s highly recommended to book Ha Long cruises and tours in advance, especially if you prefer specific itineraries or mid-to-high-end options. Early booking also helps secure better deals and avoid last-minute price surges.

Pack for Cool and Misty Weather

The temperature in January ranges between 13°C and 19°C, so make sure to pack warm layers such as sweaters, jackets, and scarves, especially for early morning or evening excursions. The weather is often misty and humid, so water-resistant shoes, a small umbrella, and a light raincoat are also useful. Don’t forget sunscreen and moisturizer, as the wind can be drying even in cooler months.

Choose Cruises Over Hotels for the Full Experience

If you’re deciding between a land-based stay or an overnight trip on the bay, January is ideal for a Ha Long Bay overnight cruise. The calm sea and fewer crowds offer a more peaceful experience, with activities like kayaking, cave visits, and onboard dining. While hotels in Bai Chay or Tuan Chau offer comfort and convenience, cruises provide unmatched scenery and immersion in the bay’s atmosphere.

Avoid Swimming and Be Mindful of Fog Delays

Swimming is not recommended in January due to the cold sea temperatures. Instead, focus on sightseeing, photography, and cultural experiences. Also note that heavy morning fog may occasionally delay boat departures, especially in early hours. Keep your schedule flexible and avoid tight transfers on cruise days. Always check the weather forecast before heading out on any day tours or seaplane flights.
