Hanoi at $915 RT

A dip in Hạ Long Bay (see above) is looking pretty tempting right about now...

Vietnam’s back in full tourist swing—but affordable high-season flights with checked bag? That’s seriously sweet. And just in time, because this is when the north really shines.

While the southern regions stay hot and dry, Hanoi cools off just enough for misty mornings, breezy strolls through the Old Quarter, and steaming bowls of phở without breaking a sweat. Bonus: Skies are often clearer in the fall and winter, making it an ideal time to sail between limestone cliffs.

Vietnam’s also got a solid rail network, so hopping between regions is a breeze. Take an overnight train down to chase the sun... Or just slow down with an egg coffee and lakeside people-watching.
