Top 3 Reasons Why Should Visit
Halong Bay & Lan Ha Bay in Autumn

Recognized as a UNESCO World Heritage Site since 1994, Halong Bay is one of the most extraordinary natural wonders in Vietnam and the world. With nearly 2,000 towering limestone islands and karsts shaped by over 500 million years of geological evolution, the bay offers a dramatic seascape of emerald waters, mysterious caves, and hidden lagoons that captivate every traveler. This breathtaking destination is not only a geological treasure but also a cultural and historical symbol of Northern Vietnam.

Just south of Halong lies Lan Ha Bay, often known as its untouched twin. While sharing the same limestone formations and stunning scenery, Lan Ha remains quieter and less crowded, making it a serene escape for those seeking tranquility. Its crystal-clear waters, pristine sandy beaches, and rich marine biodiversity make it a hidden gem waiting to be discovered.

Easily accessible within just 1.5 hours by car from Hanoi, Halong Bay has long been a must-visit destination on any Northern Vietnam itinerary. From Halong, a short one-hour speedboat ride brings you to the peaceful haven of Lan Ha Bay, where unspoiled beauty and authentic experiences await. Together, Halong and Lan Ha represent not only Vietnam’s most iconic landscapes but also essential highlights for any Southeast Asia journey.

Why Autumn is the Perfect Season

Autumn, from September to November, is the best time to experience these two bays. With mild temperatures, gentle breezes, and crisp, fresh air, the season offers the most comfortable cruising conditions. The romantic golden sunsets, clear blue skies, and calm waters create a magical atmosphere for both exploration and relaxation.

For travelers who wish to immerse themselves in this beauty, Ambassador Cruise I is the perfect choice for a Halong Bay adventure, while Ambassador Signature Cruise offers a refined journey through Lan Ha Bay with itineraries of 2 days 1 night (2D1N) or 3 days 2 nights (3D2N).

This autumn, let Ambassador Cruise take you beyond ordinary travel. From world-class dining and unique sundeck experiences to immersive excursions, discover the top three reasons why you should not miss Halong Bay and Lan Ha Bay in autumn.

Refreshing Weather – Perfect for Outdoor Adventures

Autumn in Halong Bay and Lan Ha Bay offers the most pleasant weather of the year, with cool breezes and crisp air, making it the perfect season for outdoor exploration.

Hiking with panoramic views

Travelers can challenge themselves by hiking up Titov Island in Halong Bay or Ngu Lam Peak in Cat Ba National Park. The trek to Titop takes about 30 minutes, while Ngự Lâm requires roughly an hour - both rewarding adventurers with sweeping views of emerald waters, lush green mountains, and refreshing autumn breezes at the summit.

Kayaking & bamboo boat rides

The cooler waters of autumn make kayaking even more enjoyable. As your paddle touches the bay, you will feel the chill at first, but it quickly turns into pure exhilaration. For a gentler experience, bamboo boats are also available, offering the chance to glide under limestone arches, discover centuries-old rock formations, and spot native wildlife. With Ambassador Cruise I, you can explore Luon Cave, while Ambassador Signature Cruise takes you to the Dark & Bright Cave. Life jackets are always provided to ensure safety during water activities.

The scenic 5km route allows you to pause for photos under lush canopies or beside rice fields before reaching the village, where local life and traditions are carefully preserved. For those less inclined to pedal, electric cars are available. This authentic cultural experience adds depth to your cruise journey.

Romantic Sunsets & Golden Autumn Glow
