Technically, you need a certificate from the Vietnamese version of the FAA. I don't have this certificate and heard the agency is non-responsive.
I've been flying Phantoms and my Mavic over Vietnam numerous trips since 2014. I fly into Vietnam 2 or 3 times a year. With a few exceptions, I've found Vietnam to be a very permissive place to fly. My experience over the past 4 years has been mostly positive, but taking your quad to Vietnam is not without risk.

Airports
I have entered Vietnam through Hanoi and Saigon's international airports numerous times and never had a problem. Most times, my backpack was x-rayed at customs after baggage claim. Nowadays, the Vietnamese customs officers don't even blink so I'm not sure they notice or care.
NOTE: I've read about folks flying into Da Nang on international flights and having their drones confiscated. I once flew domestically from Hanoi to Da Nang and numerous other domestic flights, and had no problems. On my flight from HAN to DAD, I went through security and one of the security officers at the Hanoi airport opened my backpack and counted my five Phantom batteries, but that's the closest I've come to being heavily scrutinized at a Vietnamese airport.
Hanoi
Hoan Kiem is a No Fly Zone and this will show up on the DJI Go apps. You can walk halfway across Long Bien Bridge and descend down stairs to an island in the middle of the Red River and launch from there, but both my P3 and my MPP hit the electronic fence when I approached Hoan Kiem. There is heavy police and military presence, overt and undercover, at Hoan Kiem Lake; I've never tried to fly there.
I was able to fly the Lotte Tower with my P3, but I've never tried to launch my MPP anywhere else in Hanoi.

Halong Bay
I assume you're going on one of the overnight cruises and I have two recommendations.
- Two nights are better than one. Your time on the bay will be busy. You'll likely be part of a tour package that has a busy schedule and you're going to want to fly as often as possible. Even on my first trip to HLB, I wish I'd taken the 2-night package and that was before drones. I flew my P3 when everyone else was paddling the kayaks around the boat.
- Select a small boat. There are two types of boats on Halong Bay. Some of them are huge, carrying up to 250 passengers. Both of my visits (2012 and 2016) to Halong Bay were on Phoenix Cruise boats, carrying about 30 passengers. Aside from the overall experience of a being on smaller boat, I felt the smaller boats would be more permissive about launches from the deck.
Keep your fingers crossed for good weather, too. Halong Bay is beautiful in the fog, but your videos will be better if it's sunny. Your boat will surely have an excursion to Titop Island for an hour or two. Take your Mavic with you and hike to the top. I did a launch from there near the pagoda at the summit.
Sapa
I have not been to Sapa. I opted for the waterfalls at Ban Gioc instead. I wanted to be the first kid on my block to fly over a border and penetrate another country's airspace.
Mitigating risk
Realize flying in Vietnam, or any other country requiring certification, isn't without risk. There's a massive statue they call Lady Buddha in Da Nang. She is taller than the Statue of Liberty in New York City. I asked the security police there if I could fly my P3. "Sure! Nobody cares," was the reply I got. I opened my backpack to show them my drone. Yes, go ahead. No problem. Within a few minutes, I was buzzing around her face like an irritating mosquito and he was right. Nobody cared.
My mistake is I took this "nobody cares" attitude and applied it to all of Vietnam. On my next trip I was in Vung Tau flying from the promenade at the beach. I went back the next day and launched again. Within minutes, I was surrounded by 6 Vietnamese Army soldiers. I was compelled to recover the drone and taken to an Army Station in the city. I was treated professionally and courteously, but they confiscated my drone for 2 weeks while they "investigated."
Some tips:
- Be tactical and stealthy. Don't launch near crowds; they will gather around you. The soldiers at Vung Tau were tipped off by a guy at the beach.
- Range is your friend. Example: if you want to fly over the Imperial Citadel at Hue, launch from at least a mile away and across the river.
- Get your footage and go. As a rule, I don't do more than two flights from the same location. Have your backpack or case be the type where you can quickly shove your gear in and go, if necessary. Sort out your kit later.
- Bribe money - I always keep a few $100 bills handy just in case. I've never resorted to using them.
- Find a pretty girlfriend who works for a company that does a lot of business with the Vietnamese military. I would not have gotten my Phantom back without her and her negotiating skills.
Have fun! Vietnam is a beautiful country and very drone-worthy and drone-friendly. I'm heading back there on Friday. Maybe I'll see you in Hanoi.
