>>2367435>Vietnam must sees:
Hanoi - the tourist area is really nice, in my opinion
Ha Long Bay - a cruise is pricey but a must do, even if just for 1 night
Hoi An - touristy but a pretty little town to see for a couple of days>Vietnam optionals:
Sapa - nice, but an effort to get to and if you go in peak season (winter) you'll probably not see much through the fog - still worth while if you have the time/money.
Ha Giang Loop - a cool drive on a motorbike - you can pay a rider to take you if you can't ride.
Ninh Binh - worth a visit if you have the time, pretty nature and some neat places to visit in the area
Hue/Hai Van Pass - worth at least a day trip if you're in Hoi An/Danang but again, if you don't drive/ride it might be more effort than its worth
Hang Son Doong - a bit out of the way, but pretty damn cool
Nha Trang - a resort town
Dalat - pretty hill station town
Mui Ne - famous dunes people rent buggies to ride on
Ho Chi Minh City/Saigon - probably a must see in truth, personally I thought it was a generic city, not a bad base for the region though
Mekong Delta - famous for its floating markets
Phu Quoc - Vietnam's answer to Thailand's beaches
