Cat Ba Beach Guide 2026: The Best Beaches on Cat Ba Island (and Where to Escape the Crowds)

Cat Ba Island, in North Vietnam, isn’t just a gateway to Lan Ha Bay—it’s a full-blown beach town playground. 

There are golden sands tucked beneath jungle-covered cliffs, hidden coves you can only reach by kayak, and screensaver-worthy sunset spots.

This guide breaks down the best beaches on Cat Ba Island, from the easy-to-reach classics to the secret spots most travellers never find.

And yes, we’ll also tell you which ones are actually worth your time in 2026 (because not all beaches are created equal).

Why Cat Ba Island Should Be Your Next Beach Escape

Let’s be honest: when most people think of “Vietnam beaches,” they picture Central Vietnam. But Cat Ba quietly does its own thing—and does it very well.

Here’s what makes it different:

• Dramatic limestone islets (similar to Ha Long Bay)

• Calm, swimmable waters (thanks to sheltered bays)

• A mix of lively social beaches and total off-grid escapes

• Easy access to kayaking, boat trips, and hidden lagoons

• A wild, rugged feel you won’t get in resort-heavy destinations

Plus, you’ve got Cat Ba National Park right in the middle of it all—so you can hike in the morning and swim by lunch. Efficient. We like that.

How to Get to Cat Ba Island  

Getting to Cat Ba Island is thankfully very easy.

From Hanoi:

• Bus + ferry combo (easiest option)

• Private transfer if you’re feeling fancy

• Travel time: ~3.5–4.5 hours

From Ha Long Bay:

• Ferry or speedboat from Tuan Chau

• Scenic, slightly smug-worthy arrival through karsts

👉 Bong Hostel tip: Book a transfer through us and skip the chaos. More beach, less bus station confusion.

Best Time to Visit the Beaches on Cat Ba Island

As is common throughout North Vietnam, timing your visit carefully is important.

Best overall months:

• March – May: Warm, dry, fewer crowds

• September – November: Golden weather, calm seas, dreamy sunsets

What to know:

• Summer (June–August): Hot, busy, peak domestic travel season

• Winter (December–February): Cooler, misty, not ideal for swimming

Also worth noting: locals tend to visit the beach late afternoon, so mornings are your best bet for quieter swims.

The Best Beaches on Cat Ba Island (2026)

Let’s get into the good stuff.

1. Cat Co Beaches (1, 2 & 3) 

If you’re staying in Cat Ba Town, these are your go-to.

What to expect:

• Clear, calm water

• Easy access (walking distance)

• A mix of chill and social vibes

The breakdown:

• Cat Co 1: Quietest, tucked between cliffs

• Cat Co 2: Social, beach bars, cold beers within arm’s reach

• Cat Co 3: Slightly more polished, a bit more space

There’s also a scenic coastal walkway connecting them, which makes for a wonderful sunset stroll.

Best for: Quick beach fixes, lazy afternoons.

2. Tung Thu Beach 

Just outside town but way more relaxed.

Why it’s worth it:

• Fewer crowds than Cat Co Beaches

• Wide sandy stretch

• Surrounded by cliffs so the water is calmer 

It’s got enough facilities to be comfortable (showers, cafés), but still feels low-key.

Best for: Chilled beach days without the chaos that comes with being closer to town.

3. Dao Khi Cat Ba (Cat Ba Monkey Island Beach) 

Welcome to Monkey Island, where the views are stunning and the furry locals might steal your snacks.

What makes it special:

• Clear water and soft sand

• Short hike to an epic viewpoint

• Kayaking access to nearby hidden beaches

Reality check:

The monkeys are cute… until they’re not. Keep your distance and your belongings close.

Best for: A little bit more adventure in your beach day, and amazing views.

4. Ba Trai Dao Beach 

Also known as “Three Peaches Beach,” this one’s a stunner.

Highlights:

• Turquoise water

• Powdery sand

• Surrounded by iconic karst formations

It’s only accessible by boat, usually as part of a Lan Ha Bay cruise—but that’s part of the magic.

Best for: Iconic photos, if you want to take a boat trip, and kayaking.

5. Van Boi Beach 

Hidden away in the bay, this is where things slow down.

Expect:

• Minimal crowds

• Clean water

• Peaceful, natural setting

You’ll likely need a boat or kayak to get here—which keeps the masses away.

Best for: Escaping everyone (in a good way).

6. Nam Cat Island Beach 

A small island just off Cat Ba that feels like a private escape.

Why people love it:

• Clear water

• Eco-style accommodation

• Kayaking and snorkelling on your doorstep

It’s the kind of place where you plan to stay one night and accidentally stay three.

Best for: Couples or families who want to get away from the main island and chill.

7. Freedom Island 

Yes, it’s actually called Freedom Island—and yes, it lives up to the name.

What’s unique:

• Two different beach sides

• Great for camping

• No overdevelopment

You can swim, BBQ, or just lie there questioning why you don’t live here permanently.

Best for: Off-grid vibes and slow travel days.

8. Moody & Tiger Beach 

Not your typical beach day—but definitely one of the most unique.

What’s here:

• Rock climbing routes for all levels

• Dramatic coastal cliffs

• A very different kind of beach experience

Even if you’re not climbing, it’s worth visiting just for the scenery.

Best for: Active travelers and adrenaline seekers

9. Secluded Beaches (The Real Hidden Gems)

Here’s the truth: the best beaches on Cat Ba Island aren’t always on Google Maps.

Some of the best moments come from:

• Kayaking into random coves

• Joining a boat tour and jumping off wherever looks good

• Finding tiny, unnamed beaches with no one else around

A couple to know:

• Beach near Woodstock Beach Camp

• Abandoned Bayview Resort shoreline (raw, but beautiful)

👉 Quick note: Some remote beaches do have litter issues, so manage expectations—but the scenery still delivers.
