Halong Bay and Lan Ha Bay, located in northeastern Vietnam, are renowned for their breathtaking landscapes. With thousands of towering limestone karsts and islets rising from emerald waters, these unique rock formations have captivated travelers worldwide, offering a glimpse into Earth’s ancient past and the natural artistry sculpted over millions of years.
Iconic rock formations in Halong Bay
Halong Bay, a UNESCO World Heritage Site, boasts over 1,600 limestone islands and islets. These formations are the result of complex geological processes spanning more than 500 million years, involving tectonic movements, sea-level changes, and the gradual erosion of limestone by wind and water. The bay’s karst landscape is a testament to the power of natural forces in shaping the Earth’s surface.
Among the myriad limestone pillars, several formations stand out due to their distinctive shapes and the legends associated with them:
Fighting Cock Islet (Hòn Gà Chọi): Perhaps the most famous symbol of Halong Bay, this formation resembles two roosters mid-fight, facing each other. It has become an emblematic image representing the bay’s unique beauty.
Stone Dog Islet (Hòn Chó Đá): This islet is named for its resemblance to a stone dog sitting atop the waters, symbolizing protection and loyalty in Vietnamese culture.
Thumb Islet (Hòn Ngón Tay): Shaped like an upraised thumb, this formation is often seen as a gesture of encouragement and positivity.
Notable formations in Lan Ha Bay: the serene neighbour
Adjacent to Halong Bay, Lan Ha Bay is a tranquil alternative, encompassing over 300 limestone islets and karst formations. While geologically similar to Halong Bay, Lan Ha Bay is distinguished by its numerous white sandy beaches nestled between limestone pillars, offering secluded spots for relaxation and exploration.
Among Lan Ha Bay’s captivating landscapes, several rock formations are particularly noteworthy:
- Turtle Islet (Hòn Rùa): This small islet resembles a swimming turtle and is located near the route from Ben Beo Pier to Viet Hai Village. Covered with lush greenery, Turtle Islet maintains its vibrant appearance throughout the year.
- Pen Islet (Hòn Bút): Also known as Bell Islet (Hòn Chuông) or Candle Islet (Hòn Nến), this limestone formation resembles an upright pen emerging from the sea. Standing approximately 30 meters tall, its base has been sculpted by centuries of wave erosion into a distinctive shape. According to local legend, this islet was a gift from the dragons who created the bay, symbolizing knowledge and wisdom for future generations.
- Frog Islet (Hòn Ếch): This formation resembles a frog poised to leap, lending its name to the surrounding area known as Frog Pond. The frog-shaped rocks here are emblematic of Lan Ha Bay’s whimsical topography.
- Resting Buddha Islet: This rock formation bears a striking resemblance to a reclining Buddha, symbolizing serenity and adding to the spiritual ambiance of the bay.

The unique rock formations of Halong Bay and Lan Ha Bay are not only geological wonders but also cultural treasures. Their preservation is vital for maintaining the area’s natural beauty and ecological balance.

Questions
When is the best time of year to visit Halong Bay?
Spring (March to May) and autumn (September to November), when temperatures sit between 20°C and 28°C with clear skies and calm seas. Summer (June to August) brings heat and a risk of typhoons; winter (December to February) can be cool and misty, with lower visibility.
Is 2 days 1 night enough, or should I choose 3 days 2 nights?
Two days and one night is enough for a first visit, with kayaking, a cave and both sunset and sunrise on the bay. Three days and two nights suits travellers who want a slower pace, deeper exploration of Lan Ha Bay or Cat Ba Island, and more time for swimming and excursions.
What happens if my cruise is cancelled because of bad weather?
Sailings are regulated by the Quang Ninh Maritime Administration for safety, mainly during typhoon season (July – August). If a cruise is cancelled before you leave Hanoi, you can usually choose a refund or a new date. If it is cancelled mid-trip, you pay only for the services already used and the rest is refunded.
Does Lyra Cruise Collection include hotel pick-up in Hanoi?
Hotel pick-up is available from the Hanoi Old Quarter as an add-on rather than part of the cruise price. Add it when you book, or ask your travel consultant.
What is the difference between Halong Bay, Lan Ha Bay and Bai Tu Long Bay?
Halong Bay is the classic UNESCO site, with landmarks such as Sung Sot Cave and Ti Top Island, and the heaviest traffic. Lan Ha Bay, to the south near Cat Ba Island, has cleaner water, fewer boats and better kayaking. Bai Tu Long Bay, to the northeast, is the quietest and most untouched.
What is usually included in the cruise price?
Usually all meals on board, entrance fees, cave visits, kayaking or bamboo-boat rides and an English-speaking guide. Hanoi transfers, drinks, spa treatments and personal expenses are normally extra.
Can cruises cater for vegetarian, vegan or halal diets?
Lyra Cruise Collection caters for vegetarian, vegan, gluten-free and allergy-related diets at no extra cost with 72 hours’ notice, and halal meals can be arranged on request.
Is there Wi-Fi and phone signal on board?
Most modern ships have free Wi-Fi, though it can weaken between the karsts. Viettel and Vinaphone 4G/5G generally works in open water but may fade near cliffs and caves.
Is a cruise suitable for young children, pregnant women or older travellers?
Most cruises welcome families, but some caves and viewpoints involve stairs. Check with the cruise about step-free options and medical support before you book.
What should I pack for an overnight cruise?
Comfortable shoes for caves, swimwear, light layers, sunscreen and a light jacket for evenings on deck. If you travel by shuttle, check its luggage allowance in advance.
