An overnight cruise on Halong Bay is more than a beautiful journey through limestone karsts and emerald waters — it is a full experience. Beyond the cabins, the spa, or the views from the sundeck, what truly makes your time on the bay memorable are the curated activities included in your itinerary.
If you’re planning your first cruise and wondering “What will we actually do onboard?”, this blog is the perfect guide. From peaceful kayaking to lively cooking classes and quiet moments squid fishing under the stars, here’s everything you can expect during an overnight adventure on Halong Bay.
Why Activities Matter on an Overnight Cruise?
A day cruise on Halong Bay gives you a taste of the scenery, but an overnight cruise immerses you in it. Activities break up the journey, create meaningful moments, bring you closer to local culture, and help you enjoy the bay from multiple angles — water level, cave interiors, sandy beaches, or outdoor decks.
These experiences are why overnight cruises remain the most recommended way to explore Halong Bay.
Kayaking — The Signature Halong Bay Experience
If there’s one activity every traveler remembers, it’s kayaking. Gliding quietly through hidden lagoons, passing close to limestone pillars, and drifting into tranquil coves gives you a unique connection with the bay that no boat can replicate.
Why Kayaking Is a Must-Do
- It brings you closest to Halong’s natural formations.
- Perfect for photography, especially in calm waters.
- A peaceful escape — even when the main routes are busy.
- Many areas are accessible only by kayak.
What to Expect
A typical kayaking session lasts 45–60 minutes, with double or single kayaks available. Life jackets are mandatory, and you’ll be guided to safe, scenic routes. Depending on your cruise, you might kayak in:
- Luon Cave area — calm waters in a circular lagoon
- Ba Hang fishing village — peaceful, cultural surroundings
- Vung Vieng (Bai Tu Long Bay) — pristine, quiet
- Hang Bo Nau or Dark–Bright Cave — sheltered and picturesque
Even beginners can join, as the waters of Halong Bay are usually very calm.
Cave Exploration — Halong Bay’s Geological Treasures
Halong Bay is home to some of Vietnam’s most impressive caves, formed over millions of years. Visiting a cave is like stepping into another world — giant chambers, shimmering stalactites, mysterious rock formations, and cool temperatures that feel like natural air conditioning.
Why Caves Are Famous
- They bring the story of Halong Bay’s geology to life.
- Each cave has its own shapes, legends, and atmosphere.
- They offer an easy, enjoyable walk for all ages.
Popular Caves on Overnight Cruises
• Sung Sot Cave (Surprise Cave)
The largest and most famous cave in the bay. It features two vast chambers with dramatic lighting and impressive formations.
Expect a 30–45 minute walk with steps leading to panoramic views at the exit.
• Thien Canh Son Cave
Often included in premium cruises operating in Bai Tu Long Bay. Smaller, quieter, and known for its dreamy, photogenic interior.
• Dark & Bright Cave (by bamboo boat)
A serene, narrow water cave leading into a hidden lagoon — ideal for photography.
Caves are a beautiful contrast to time spent on the boat — adding both adventure and education to the journey.
Island Visits — Beaches, Views & Short Hikes
Island visits let you stretch your legs, swim, relax on the beach, or climb to stunning viewpoints overlooking the bay. They are especially fun for families and active travelers.
Why Visit an Island?
- Gives you a chance to swim in warm seasons.
- Provides “Instagram-perfect” bay viewpoints.
- Offers a refreshing change of scenery.
- Creates memorable moments outside the cruise ship.
Common Islands on Overnight Cruises
• Titop Island
The most well-known island for overnight cruises. Features:
- A clean sandy beach
- A viewpoint at the top of ~400 steps
- Wide panoramic views of the bay
It can be busy in high season, but the view is worth the climb.
• Soi Sim Island
A quieter alternative with a softer, more natural atmosphere but the island is still closed now
Onboard Cooking Class — A Fun Taste of Vietnamese Culture
One of the most enjoyable activities on an overnight cruise is the Vietnamese cooking demonstration. It’s short, interactive, and brings you closer to the cultural heart of Vietnam: its cuisine.
Why Cooking Class Is Popular
- It’s easy and fun for all ages.
- A great way to connect with other guests.
- Helps you understand Vietnamese ingredients.
- You get to taste your own creation!
What Usually Happens
In the late afternoon or early evening, the staff gathers guests on the sundeck or in the dining room. You may learn how to:
- Roll fresh spring rolls
- Make fried spring rolls (nem)
- Prepare dipping sauces
- Decorate simple dishes
The session lasts 15–20 minutes and usually leads into sunset drinks or pre-dinner time.
The activity is lighthearted, social, and often becomes one of guests’ favorite memories.
Night Squid Fishing — A Quiet and Relaxing Experience
After dinner, when the bay falls silent and other boats anchor nearby, guests can join one of the most traditional local experiences: squid fishing.
Why Squid Fishing Is Unique
- It offers a peaceful moment under the stars.
- It reflects the life of local fishermen.
- It’s simple, relaxing, and surprisingly fun.
What to Expect
The crew sets up rods, lights, and small fishing lures to attract squid. You stand at the stern of the boat, gently lifting and lowering the rod. Sometimes you catch one; sometimes you don’t — but that’s part of the charm.
Best Season
November to March usually offers the best chances of spotting squid.
Tips
- Bring a warm jacket — evenings can be breezy.
- Be careful near the railings.
- Even if you don’t catch anything, enjoy the quiet ambiance.
Squid fishing is less about results and more about soaking in the atmosphere of Halong Bay at night.
Bonus Activities on High-End Cruises
Depending on the ship, you may enjoy:
- Morning Tai Chi or Yoga on the sundeck
- Sunset cocktails
- Spa & massage treatments
- Tea tasting sessions
- Board games or mini library
- Cinema or lounge activities
Luxury cruises typically offer more wellness-style options to complement the scenery.
