Route Briefing: London to Hanoi
Hanoi is one of those cities that genuinely rewards the effort of getting there, and from London, that effort amounts to around eleven and a half hours in the air with one stop — entirely manageable for what awaits on the other side. Vietnam Airlines flies the route directly from their home turf, while Cathay Pacific routing through Hong Kong and Qatar Airways via Doha both offer strong options that frequently undercut the standard fare. Speaking of which, standard tickets tend to sit above nine hundred pounds return, but patient bookers who plan three to six months ahead can regularly find deals under six hundred — a significant saving worth building your schedule around.
Timing matters in Hanoi more than in many Asian capitals. The city sits in northern Vietnam and experiences genuine seasons, unlike the tropical south. June through August brings heat and humidity alongside the summer holiday crowds, while December and January offer cooler, drier weather that makes wandering the Old Quarter genuinely pleasant rather than sweaty. Both windows are peak season for good reason, so if you're flexible, the shoulder months of March, April, or October can offer a quieter, more atmospheric experience of the city.
And the Old Quarter is where Hanoi earns its reputation. This tangle of narrow streets, each historically dedicated to a specific trade, is chaotic in the best possible way — motorbikes weaving past French colonial shopfronts, vendors balancing bamboo poles loaded with produce, and the smell of pho drifting from doorways at six in the morning. Hanoi's street food culture is extraordinary: bun cha, banh mi, egg coffee, and cha ca are all dishes with deep roots here, and eating well costs almost nothing if you follow the locals to the plastic-stool spots rather than the tourist-facing restaurants.
Beyond the food, Hoan Kiem Lake sits at the heart of the city like a breathing space amid the noise, and the Temple of Literature offers a genuinely beautiful glimpse into Vietnam's scholarly history. The Ho Chi Minh Mausoleum complex is sobering and fascinating in equal measure.
From Noi Bai International Airport, the city centre is roughly thirty kilometres away. The public bus service connects the airport to the city at very low cost, while metered taxis and ride-hailing apps offer a more direct route — just ensure you use a reputable service or agree on a fare before setting off to avoid the overcharging that can catch new arrivals off guard.
One tip worth taking seriously: book your Old Quarter accommodation before you arrive. The neighbourhood's most characterful guesthouses fill up fast, and staying inside it rather than near it makes an enormous difference to how the city feels.
