As Vietnam’s capital, Hanoi is home to an abundance of landmarks and must-see sights, from temples and lakes to night markets. Hanoi’s famed Old and French quarters make up just part of this incredibly vibrant city. With a turbulent history (still very much on display), there remains much to discover in what used to be the beating heart of French Indochina. And whilst travelling, it’s noteworthy to think about Hanoi weather to find out the best time you can visit this beautiful capital city.
