Why Lan Ha Bay is Our Favorite Alternative to Ha Long Bay
When you think of northern Vietnam, your mind probably wanders to the soaring limestone karsts of Ha Long Bay: towering rock formations rising from emerald water, and traditional junks drifting through the mist.
And rightly so – it is one of the most iconic landscapes in the country for a reason.
But just south lies Lan Ha Bay, a quieter bay that offers much of the same jaw-dropping scenery, only with calmer waters, fewer crowds, and a more local feel.
This isn’t about declaring which one is ‘better’. Ha Long Bay remains extraordinary, and we still visit on several of our Vietnam adventures.
But if you’re seeking a more peaceful experience – the kind where you hear paddles dipping into the water and birdsong echoing across the bay – Lan Ha Bay is the most rewarding alternative. Here’s why.
The scenery is just as spectacular
Let’s start with the obvious question: does Lan Ha Bay actually look like Ha Long Bay?
In short, yes, very much so.
Lan Ha Bay forms part of the same vast limestone karst landscape shaped over millions of years by tectonic activity and erosion. The result is the same dramatic scenery: jungle-cloaked limestone towers rising from jade-green water.
Ha Long Bay may be the larger of the two, with approximately 1,600-2,000 limestone islands and karsts, while Lan Ha Bay has around 300-400. But despite being smaller, Lan Ha feels no less cinematic.
This may be because there are far fewer cruise boats navigating the waterways, and the karsts are more tightly clustered, so the scenery often feels even more immersive.
There’s also something wonderfully dramatic about arriving in Lan Ha Bay. The further you cruise from the mainland, the quieter things become.
The water calms, the cliffs envelope you, and suddenly it feels as though you’ve stumbled into a secret corner of Vietnam that hasn’t entirely given itself away yet.
Bright Cave reveals a quieter side of the bay
One of the highlights of visiting Lan Ha Bay is exploring the Dark and Bright Caves (Hang Sáng – Tối), a limestone cave system tucked among the karst cliffs of the Cat Ba Archipelago.
While the two caves form part of the same geological network, visitors typically explore Bright Cave, a natural passage that offers access to one of the bay’s quieter corners.
Named for the contrast between them, Bright Cave is naturally illuminated. And on our Best of Vietnam adventure, you’ll cruise into the heart of Lan Ha Bay before exploring Bright Cave by kayak or traditional bamboo boat.
As you pass beneath the cave’s low ceiling, you’ll notice rock walls smoothed by centuries of tidal movement, along with pockets of vegetation clinging to cracks in the stone. The natural archway frames the surrounding karsts, while light reflected from the water creates ever-changing patterns across the rock.
The surrounding cliffs and waterways are also home to an array of wildlife, and if you’re lucky, you might spot macaques in the trees above or kingfishers flashing across the water. The limestone has spent millions of years perfecting the view – and it shows.
For generations, local fishing communities navigated these waterways as they moved between fishing grounds and sheltered anchorages. Today, exploring Bright Cave offers a glimpse of a quieter side of Lan Ha Bay and a fascinating insight into how this dramatic landscape has been shaped by both nature and people over thousands of years.

Lan Ha Bay feels more connected to local life
Another reason travelers warm to Lan Ha Bay is that it feels closely tied to the communities that live around it, particularly around Cat Ba Island.
On our Hiking Northern Vietnam trip, you get the opportunity to pass by floating fishing communities such as Cai Beo – one of the oldest fishing villages in Vietnam, believed to date back thousands of years – where colourful homes bob gently between the karsts and life still revolves around the water.
There’s an opportunity to kayak through the bay itself, slipping between limestone outcrops and quieter corners unreachable by larger boats.
Nearby oyster farms and floating seafood platforms are scattered across the bay too, with locals cultivating oysters, fish and pearl mussels using traditional methods that have sustained families here for generations.
Compared to some of the busier routes in Ha Long Bay, there’s a stronger sense here that everyday life continues at its own pace – tourism exists, certainly, but it hasn’t taken over the landscape.

Hiking in Northern Vietnam
Leave the backpackers and hike the remote north with a leader who knows the trails better than any
Our Hidden Vietnam Sapa & Beyond trip also offers a kayaking excursion across this part of the wider Cat Ba Biosphere Reserve, a UNESCO-recognised protected area known for its rich biodiversity and striking mix of limestone karsts, mangroves and rainforest-covered islands.
After time on the water on this adventure, your group retreats to Cat Ba Ecolodge, a family-run hideaway tucked into the forested hills of Cat Ba Island. It’s a place where bamboo bungalows, locally sourced dinners and the warm welcome of the hosts make it feel less like a hotel stay and more like being let in on a well-kept secret.
Fewer crowds, more calm
Ha Long Bay welcomes millions of visitors each year, and while tourism has brought significant economic opportunities to the region, it has also created challenges around overcrowding – particularly during peak travel periods.
Certain parts of the bay can become extremely busy with day boats, tourist traffic and overnight cruises all sharing the same routes.
Lan Ha Bay offers a noticeably quieter alternative. We have seen tourism increase here too, in recent years, but the bay still sees far fewer boats overall, particularly large cruise vessels. The atmosphere is calmer, slower and, frankly, a little easier to sink into.
That difference becomes especially noticeable when kayaking. Instead of navigating through clusters of boats, you’re more likely to glide through peaceful stretches of water where the loudest sound is the splash of your paddle or the occasional creak of bamboo from a nearby fishing boat.
From the hidden lagoons of Lan Ha Bay to the legendary karsts of Ha Long Bay, our Vietnam adventures showcase the best of both. Browse our full collection of Vietnam adventures.
