Vietnam’s northeast is one of Southeast Asia’s best-kept secrets. The Cao Bang Loop is a remote motorcycle circuit right at the Vietnam-China border — jaw-dropping karst landscapes, authentic ethnic minority villages, and zero other tourists for long stretches. It’s also raw, unpredictable, and occasionally chaotic. This guide covers everything: getting there, surviving Hanoi, renting a motorcycle, and all the highlights on the loop itself. Real talk included. 😂
Not up for the DIY? Book a guided day tour with free pickup from Cao Bang City instead.

When to go?
Hanoi is Vietnam’s capital city, located in the north side of the country. Cao Bang is the northernmost part of Vietnam- bordering China. These areas do experience four seasons! The best time to go is from October to April, when the weather’s cooler. March to April is when flowers bloom in Cao Bang.
Getting There: Jakarta to Hanoi 🛫
We flew VietJet from Jakarta; a decision that definitely had us nervous. There are plenty of TikTok horror stories about strict carry-on weighing and long delays. Thankfully, my trip went fine.
Soekarno-Hatta (CGK airport) accepted our online check-in QR without printed boarding passes (works as long as Hanoi is your final destination, no transfers). We also only had carry-ons, which allowed us to solely do online check-in. Carry-ons weren’t strictly weighed at the gate. No food or drinks on board; bring your own snacks. Flight was 4 hours 15 minutes to Hanoi’s Noi Bai International Airport, which went smooth enough.
Pro Tip: General consensus is to book Vietnam Airlines over VietJet. The one advantage VietJet has is its significantly cheaper price! If you’re flying direct, it’s workable. Just bring snacks (and prepare to be extra patient if there are hiccups). 🍿
Scammer Alert: Hanoi Edition 🥷
Hanoi has a genuine scammer problem; just open Reddit and you’ll see plenty of stories! Here’s what to watch for and how to stay safe.
Common scams:
- Airport taxi: Rigged meters or “broken” meters that charge whatever at the end.
- Wrong change: Vietnamese bills are unfamiliar to tourists; scammers swap or shortchange quickly.
- Pickpockets: Fast motorbike riders snatch bags. Wear your bag in front.
- Fruit seller photos: They hand you the wooden poles for a cute photo, then aggressively demand payment.
How to protect yourself:
- Get a Viettel SIM at the airport or an eSIM before you fly.
- Download Grab with your credit card connected. Price is fixed before you book. Always match the driver’s plate number to the app before getting in.
- Use Xanh SM (green taxis) as a Grab backup during surge pricing.
- Break large 500K VND bills at Circle K, Winmart, or Vincom Mall; never at street stalls.
- Carry two wallets: one for large bills, one for small change (10K–100K VND), in separate places.
- Say NO firmly if you think something’s fishy and don’t waver!
What happened to us: At Noi Bai Airport, someone showed us a phone translation saying Grab was “closed for the holiday” (it was a day before Vietnam’s Independence Day). Absolutely not true- ridesharing apps don’t shut down for public holidays. We ignored them and waited for a Grab driver to come through. Grab pickup is in the parking building across from Arrivals– short walk, worth it.
If you don’t want to DIY the Cao Bang Loop
Definitely fair! Especially if you’re nervous about riding motorcycles alone on mountainous roads. Not to mention motorcycle engine issues- which we went through… 😭
You can book a 3D3N Cao Bang loop adventure with experienced easy riders. It includes food and accommodation for $254.20 at the time of this posting. For a shorter 2D Cao Bang loop trip, you can choose a car or motorcycle options with comparable prices. Ha Giang loop is a more popular route, and booking this route includes food and accommodation as well.
Transport: Hanoi to Cao Bang City
After one night in the Old Quarter, head northeast. Two main options:
| Sleeper Bus | Limousine Van | |
|---|---|---|
| Duration | ~8 hours | ~6 hours |
| Pickup | Bus station | Multiple points (we used Hanoi Opera House) |
| Drop-off | Bus station | Your hotel / homestay |
| Cost | 300K–380K VND | 370K–380K VND |
| Notes | Reckless driving, scarier at night | Still reckless, but smaller vehicle |
We booked the limousine van, specifically Trùng Khánh Limousine via Vexere (which was cheaper than 12Go.asia). The driver contacts you on WhatsApp, picks you up at the Opera House, collects a few more passengers along the way.
Our driver was aggressively fast- think Vietnamese Fast & Furious- but the mountain scenery made up for it. Two rest stops en route; go light on water beforehand, the squat toilets aren’t great.
Where to Stay in Cao Bang City
Cao Bang Eco House is where we spent the first night. Modest, clean, right on the Sông Bằng River. Also rents motorcycles, which is handy. The riverside comes alive at night: locals out for duck pho, river-view cafes, roller skating, and a bouncy castle inexplicably set up by the street. The bridge lights up in colour. It’s one of the more charming small-city evenings I’ve had anywhere in Southeast Asia.
Motorcycle Rental: What We Got Wrong at Cao Bang Loop
Eco House rents bikes and is fairly known for their quality. Just rent from them. We found a separate agency with great Google Maps reviews instead, and that’s where everything that could go wrong, went wrong.
The owners were warm and thorough- checked our International Driver’s License, rented out helmets, bungee cords to tie our bags, knee and elbow guards. Test ride was perfect. We rented a semi-automatic Honda for two days at 600K VND total, confirmed our itinerary with them: Angel’s Eye Mountain, Ban Gioc Waterfall, Nguom Ngao Cave. Manageable. Famous last words.
What went wrong: The engine overheated. Repeatedly. A repair shop topped up the coolant mid-Day 1 and told us to pour water over the engine if it acted up again (now I know it’s debatable advice 😂). Day 2, it gave its final death rattle near Truong Khanh. The rental company eventually sent an easy rider to escort us back to Cao Bang City. They offered compensation; we declined. The breakdowns is part of the story I guess.
What to do instead:
- Inspect coolant, brakes, and tire pressures yourself before leaving; don’t assume the rental shop has.
- Keep the rental owner’s number handy and check in throughout the ride.
- Download Google Translate offline with Vietnamese. Show them mechanical problem phrases specifically.
The Loop: What to See
Angel’s Eye Mountain / God’s Eye Mountain (Núi Mắt Thần) 🏔️
~1 hour from Cao Bang City
Erosion carved a perfect 50-metre circular opening through the mountain peak — the valley below is framed like a painting. In Tay language it’s called Phja Piot, meaning “mountain with a hole through it.” The trek from the parking lot is minimal, only 10–15 minutes. We met only a couple tourists. The Thang Hen Lake System below is worth a look too — water levels shift with the seasons via underground flows. Boat rides on the lake are available if you want to get closer; we skipped it.
Ban Gioc Waterfall (Thác Bản Giốc) 🌊
2 hours from Cao Bang City
The 4th largest waterfall straddling two countries in the world! We could see the Chinese flag visibly on the opposite bank. There are two falls: the main and subordinate, which can merge in high-rainfall seasons.
Finding the entrance is genuinely confusing. The Google Maps pin drops you into a cluster of yelling parking attendants and souvenir shops. Park (10K VND), walk into the alley behind the shops, find the tucked-away ticket counter. We also rented a conical hat decorated with a Vietnamese flag for 5K VND, which was definitely the move for iconic photos!
Don’t skip the boat ride (50K VND). It brings you close enough to feel the spray and puts you right at the Vietnam-China border. Multiple viewing platforms on land are also well-maintained. Friendliest local tourists we met on the whole trip were here; ended up swapping photos with a couple we’d just met.
Khuoi Ky Stone Village 🗿
Overnight stop
We rolled in just as golden hour hit, after the Day 1 engine saga. It was worth every stressful kilometre.
A 400-year-old Tay ethnic minority village where all the stilt houses are built entirely from stone. Each house can take 2–3 years to construct. Only 14 houses remain, occupied by 16 households.
Stone is sacred here; the villagers worship the Stone God for protection. Surrounded by mountains and a clear river stream, it’s one of the most idyllic overnight spots I’ve come across anywhere. Stay the night if you can.
Nguom Ngao Cave (Tiger Cave) 🐯
Near Khuoi Ky Stone Village
- Cost: 45,000 VND standard / 195,000 VND guided- cash only
- Visit time: ~40 minutes (standard route)
- Hours: Check locally; we arrived at 10am on a weekday and had it almost to ourselves
Part of the Non Nuoc Cao Bang UNESCO Global Geopark since 2018. The cave is 400 million years old and 2.1km long; the public route covers about 1km. The guided ticket takes you beyond that.
The formations are enormous. The coral stalactite alone is about five people tall. The most famous is the upside-down lotus stalactite — legend says a monk, frustrated after years of failed meditation here, kicked his lotus platform down. The impressive lotus-shaped limestone result is now the cave’s most-photographed spot. 🪷
It gets narrow in places; you’ll need to squat at one point to get through. Wear non-slip shoes; it’s damp and dripping. Not wheelchair accessible.
Where to Stay on the Cao Bang Loop
Lan Rung Homestay (Khuoi Ky Stone Village). Right in the village, perfect location. Their restaurant was closed when we arrived (Vietnam Independence Day), but we were able to get a meal at Tay Homestay next door without issue.
Where to Eat
Savory
Bánh Cuốn Phố Cũ (Cao Bang City): The local favourite for banh cuon breakfast. Silky steamed rice sheets around seasoned pork, topped with crispy shallots, served with bone broth, a delicate roll, and pork sausage. One full set costs 30K VND (~$1.15 USD). Honest caveat: I found a flattened mosquito garnishing one end of my roll. The flavour was so comforting it almost didn’t matter. Almost. 😅
Duck Pho / Pho Vit (Cao Bang City riverfront): A Cao Bang specialty. Follow the locals to the riverside restaurants in the evenings.
Tay Homestay restaurant (Khuoi Ky): Pork belly, bok choy stir-fry, tomato-tofu, warm rice. Exactly what you need after a breakdown-filled day. The menu listed “bee larvae” — watching staff extract them from what was clearly a wasp nest was enough for us. We passed. No regrets.
Duck pho near Ban Gioc: Restaurant appeared completely empty on arrival; required translate-app negotiation to locate the owner. Hygiene was questionable. Broth was genuinely good.
Coffee & Drinks
Cafe Lapin (Cao Bang City riverfront): The local go-to for evening drinks, colourful teas, and sunflower seeds by the river.
Cafe near Nguom Ngao Cave: Mango smoothie and Vietnamese sea salt coffee. Essential fuel before a 400-million-year-old cave. 🥭
Login Cafe (mid-loop, Day 1): Our refuge during the first motorcycle breakdown. The owner pointed us to a repair shop and didn’t judge us once.
Practical Tips for Cao Bang Loop
- Best time to go: October–April. Avoid June–September (rainy season! mountain roads get dangerous and slippery)
- Motorcycle: Inspect coolant, brakes, and tyre pressure yourself. Don’t assume.
- Language: Google Translate offline, Vietnamese downloaded. Screenshot phrases for mechanical problems, medical needs, and directions.
- Accommodation: Book ahead during Vietnamese national holidays!! Family-run places close.
- Food: Pack probiotics and basic meds. Go cautiously on raw vegetables from street stalls.
- Cash: Many attractions only accept cash (Nguom Ngao Cave confirmed). Have small bills ready.
- International Driver’s License: Required for motorcycle rental. Make sure to bring one.
- Not doing DIY? The guided day tour covers all the highlights in one day from Cao Bang City, with free pickup.
The Cao Bang Loop isn’t polished travel. There are no guarantees, English support is minimal, and the bikes don’t always cooperate. But somewhere between pushing a motorcycle through a rice paddy and watching the mist rise over Ban Gioc, something clicks that hey.. that’s life!
There are a lot of warmth that we experienced as well. Locals who don’t speak your language will still help you (they are SO NICE, I cannot emphasis this enough!). A little girl ran to get us a bowl of water. A group of women filled up our water bottle.
Our escort easy rider took us to a knife artisan village that wasn’t in our original itinerary. The rental company offered compensation for the motorcycle troubles; we declined. The adventure, breakdowns and all, had become the story. Sometimes how you handle hardship is what makes the adventure 😊
Go if you can handle real travel. You won’t regret it. 🏍️
Back in Hanoi after the loop, we went straight to the legendary Bun Cha Obama. Some rewards are well-earned. 🍜
