15 Best Things to do in Halong Bay, Vietnam

Halong Bay is one of the best places to visit in Vietnam. Have you ever heard of this amazing place? If you haven’t, I hope that we are about to blow your mind with a few images of this enchanting place. When we booked a last-minute trip to Vietnam, we arrived without plans but knew we had to get to Halong Bay.

It wasn’t until we were already in Hanoi that we debated going on a Halong Bay cruise, which was one of the best things to do in Halong Bay! Halong Bay is one of Vietnam’s most well-known tourist attractions, but that can sometimes lead to questionable destinations full of tourists. However, after the advice of many, we had to Halong Bay for ourselves.

We didn’t know what to expect, but now it remains a highlight of all our travels worldwide. If you find yourself in beautiful Halong Bay, here are all the amazing things you can do!

The Best Things to do in Halong Bay

Take a boat cruise

One of the first things you should do upon arrival to truly see and appreciate the beauty of Halong Bay is to take a Halong Bay boat cruise around the bay. Halong Bay covers a vast area comprising some two thousand islands. You could take one of these cruises every day and still discover something new. 

There are different options for these cruises (usually on traditional Vietnamese-style boats), whether you want an inexpensive, authentic experience or something a little more elevated like an overnight cruise with food packages included.  We personally cruised on the Au Co for three days which was so amazing!

Note* A multi-day Ha Long Bay cruise with a full itinerary is one of the best things you can do in Ha Long Bay. Many of the things I’m about to mention are included in a two or three-day cruise itinerary. It would be logistically easier to book a Ha Long Bay cruise and let them handle the logistics for you rather than doing all of these on your own!

  • Insider Tip: For something a little more adventurous, try a multi-day kayak tour, where you can spend the night sleeping in caves.

Visit Cat Ba Island

Best Things to do in Halong Bay

This is definitely one of the more popular islands in Halong Bay, and for very good reason. Some of the most popular things to do on the island include a bike tour, hiking Cat Ba National Park (see if you can spot any langurs among the nearly three dozen varieties of animals on the island), and a central market where you’ll find the freshest vegetables, fruits, and seafood, including crab and shrimp.

You can also visit Hospital Cave and Two Cannons Fort, both historical remnants of the Vietnam War. The Hospital Cave, in particular, is fascinating. It was a fully-functional secret hospital during the war that was located deep in a cave impervious to the bombing.

  • Location: Cat Ba Island
  • Insider Tip: Cat Ba is one of the boats of the main port leave for cruise tours, so this is a great spot to choose as your base in the area.

Go diving or snorkeling

Tasha Diving Kuramathi

The marine life in the area is incredibly vibrant and diverse. This is an ideal spot for a little underwater exploration combined with very clear waters. Among the sea life, you might be able to spot cuttlefish, crustaceans, or even octopi. Don’t miss the underwater grottoes; they are truly magical and otherworldly.

There are diving schools nearby to give you quick crash courses in the diving basics, but all boat cruises will offer snorkeling stops if you prefer not to go as deep. Note that December is generally considered the best month to dive since water temperatures are ideal.

  • Insider Tip: The best diving spots are near Van Gio Island, Cong Do Island, and Trai Cave. This is where the highest concentration of coral reefs can be found.

Check out the karst formations

Halong Bay Cruise

The best way to explore these awe-inspiring rock formations is by kayak since you won’t be able to do this on foot! The area is rich with what are known as karst formations.

The island-like rocks you see scattered around the Ha Long Bay region are made from limestone or similar rock and worn away by the water near the bottom so that the base appears narrower than the upper areas. Many of these rocks are so huge that you can kayak right underneath the negative space near the base! 

  • Insider Tip: If you have a waterproof camera, this is the time to break it out – the photos you’ll leave with will be unparalleled. 

Take a seaplane

Best Things to do in Halong Bay

This is the best way to get a bird’s eye view of Ha Long Bay and appreciate the region’s beauty from above. These tours can be as cheap as 2.3 million dongs (or, if your guide accepts USD, around USD 99) and usually leave from nearby Hanoi. There is currently just a single company offering these tours – Hai Au Aviation.

The 25-minute ride will take you on an incredible aerial tour of the Ha Long Bay region, with the pilot pointing out specific areas of interest. If you’re not afraid of heights, this is definitely something you should add to your list of things to do in Ha Long Bay.

  • Location: Leave from Hanoi (72 Bà Triệu, Trần Hưng Đạo, Hoàn Kiếm)
  • Insider Tip: The company also offers quick trips between Hanoi and Tuan Chau—better than a four-hour car ride.

Go parasailing

Another activity that’s not for the faint of heart, nor those afraid of heights, is parasailing. With such an expanse of clean, clear blue waters, many companies offer parasailing adventures for those who want to feel like they are flying above the world.

You’ll be soaring at the height of about 35 stories off the water, and the sweeping views of the whole area are hard to beat—especially as you take in the rich blue of the water and the lush, jungle-like nature sitting atop many of the bay’s islands.

  • Insider Tip: This is a good time for the GoPro camera you’ve wanted to test out (go for the chest strap for a hands-free experience)

Explore the ‘Bewitching Grotto’

Things to do in Vietnam

With a name like ‘The Bewitching Grotto,’ it’s impossible not to want to visit. Known locally as the Me Cung Cave, this is one of the dozens of enchanting cave grottoes in the Ha Long Bay area, but also one of the most beautiful and most visited.

Be warned; the entrance to this cave is quite narrow, but once you’re inside, it opens into a cavernous inner chamber full of winding tunnels with ceilings full of stalagmites and stalactites. If you’re really up for an adventure, there are also options for guided spelunking inside the cave. You’ll come across a fair few fossils for your efforts.

Note* If you’re on a multi-day Halong Bay cruise, this activity will likely be included in the cruise itinerary.

  • Location: Me Cung Cave
  • Insider Tip: Those with limited abilities or afflictions like asthma or claustrophobia might want to sit this out.

Ha Long City

If you’re visiting Ha Long Bay, chances are you’ll be using nearby Ha Long Bay City as your jumping-off point. But there’s so much to do here that you may want to stay an extra couple of days to experience it all. 

Since the city has grown with the increase in tourism, there are a lot of hotels in the city. These are a good option if you enjoy the popular boat cruises but aren’t keen on spending the night on the water. The city is divided into two parts – Bai Chay (more catered to visitors and tourists, with hotels, restaurants, and bars), and Hong Gai, the local area.

  • Location: Ha Long City
  • Insider Tip: Don’t miss the local delicacy – gio, a minced pork dish.

Bai Chay Market

This one is for you for anyone who is a fan of markets. The Bai Chay market is a huge indoor market in Ha Long City. It’s situated in prime proximity to the day of island adventuring you have planned.

Not only does the market have stalls selling the freshest fruits, vegetables, and tantalizing seafood, but clothing and textiles are also sold. This market typically caters to locals, so you are guaranteed a really authentic experience. 

  • Location: Đường Anh Đào, Bãi Cháy, Thành phố Hạ Long, Quảng Ninh 202400
  • Insider Tip: The evenings are typically considered best since nearby nightlife will trickle into the market area.

Lan Ha Bay

Ha Long Bay is a UNESCO World Heritage Site. He is easily accessible to travelers, so it’s not surprising that the area sees an extremely high volume of tourists all year round. As such, the area can sometimes feel overcrowded, especially during the high season (October through December).

If you want to visit at a busier time of year but avoid the crowds, don’t miss Lan Ha Bay. It’s in a quieter part of the region and has all the best elements that any other busier island offers, such as sandy white beaches, crisp, clear water, and tons of things to do, like swimming, hiking, rock climbing, and snorkeling. 

  • Location: Lan Ha Bay
  • Insider Tip: If you’re in it for the history lesson, this area is also home to some of Vietnam’s oldest floating houses.

Visit the Virgin Cave Shrine

This is more of a local legend, but the cave is real. Hang Trinh Nu is a famous grotto in the Ha Long Bay area, but its heartbreaking story is even more famous. Legend has it that a woman who was trapped in a loveless marriage ended her life inside the cave. There are two endings to the story.

One says that her body turned to stone, and another states that she was found and buried by local fishermen—one of whom was the man she was truly in love with. Today, a shrine is dedicated to the woman inside the grotto, which remains a popular attraction in the Ha Long Bay area. 

  • Location: Bo Hon Island
  • Insider Tip: The cave itself has multiple caverns and tunnels that wind through the rock, so there’s more to this stopover than just the shrine.

Visit Monkey Island

Uluwatu Temple

Monkeys may be sneaky little troublemakers, but there’s something irresistible about them nonetheless. In Ha Long Bay, there’s even an island (aptly named Monkey Island in English, or locally known as Cat Dua) where you can spot them in the wild.

Aside from the local wildlife, Monkey Island is a popular stop on many boat cruises, and for a good reason. There’s a hike to the summit with incredible views, white sand beaches for sunbathing, and crystal clear waters perfect for snorkeling or just going for a swim. 

  • Location: Cat Dua Island
  • Insider Tip: Monkeys can be aggressive if you get too close, so don’t approach them.

Night fishing for squid

Best Things to do in Halong Bay

If you’re doing an overnight cruise, many will offer a pretty unique experience – night-time squid fishing. Cruise management provides all the necessary equipment, and when darkness falls, the small squid flock close to the water’s surface.

Once you’ve netted your catch of the night, it will be barbecued up on deck so that you can enjoy your dinner. Guests with some fishing experience can expect to catch around two dozen squid! Ideal fishing seasons are from April through January, with the best times being October through November.

  • Insider Tip: Regardless of the season, this is a weather-permitting event.

Go hiking on Ban Sen Island

Halong Bay Cruise

If you’re feeling fed up with crowds and interested in doing something a little more off the beaten path, then Ban Sen Island is the haven you’ve been seeking. This is a much less traveled island in the Halong archipelago. Few roads and wilder foliage exist than on many islands with more human occupation. Because of its more challenging terrain, it makes for a great getaway.

If you’d like a guide who can show you the ropes and the best-hidden spots on the island, find one in Cai Rong before you leave. While you’re on the island, don’t miss out on local delicacies like Sen oranges and farmed seafood like oysters and geoduck (clams).

  • Location: Start from Cai Rong and catch the ferry across to Quan Lan. 
  • Insider Tip: There are no roads or facilities whatsoever on the island, and it’s extremely densely forested, so this is better suited to a quick day trip.

Visit Tuan Chau 

Best Things to do in Halong Bay

This schist island is connected to Halong City by a land bridge. It’s composed partially of human-made beaches and partly of volcanic rock formations that created even more caves. Don’t miss Dau Go Cave. Just a quick ferry ride over from Tuan Chau. This enormous and impressive cave is full of stalactites and stalagmites and illuminated with artificial light to make the inside appear even more otherworldly. 

Check out the island’s marina. This is an important entryway into the Ha Long Bay region, and all manner of interesting vessels dock here or pass through. You likely won’t spend much time here, but there are definitely some interesting points while you use it as a jumping-off point.

  • Insider Tip: This area is also rich in archeological history: remnants from early peoples have been found all over the island.

Our Recommendation For Travel Insurance

Things to do in Nara

We don’t travel without travel insurance, and neither should you. You never know what can happen in a foreign country, and it’s best to be prepared. HeyMondo offers excellent short and long-term travel insurance policies.

Sometimes it’s nice to let someone else do the work! 

Grayl Waterbottle
Travel Water Bottle

Plastic pollution is a problem in Vietnam, so it’s best not to contribute to it by buying plastic water bottles everywhere – plus, the water from the taps here is perfectly safe to drink. We’ve shifted to using an insulated aluminum water bottle as it handles the hot sun well.

However, we also love filtered water bottles in areas uncertain of the water supply. Read more about your favorite water bottles for travel in our post.


Remember that Vietnam uses the Type C adaptor. Make sure you find a good universal adapter like the one I have to keep you charged. Otherwise, you may be paying for a cheap one once you land.
