🏮 Hoan Kiem Lake & the Old Quarter
The heart of Hanoi: a lake with the red The Huc Bridge and an island temple, ringed by 36 old streets, each of which once sold its own trade: silk, silver, paper lanterns.
Price: Free; Ngoc Son Temple about 30,000 ₫
Insider tip: From Friday evening to Sunday the streets around the lake are closed to cars and bikes: walk, eat and watch the street musicians. At 6 am locals dance and exercise by the water.

📜 Temple of Literature
Vietnam's first university, founded in 1070. Five quiet courtyards with ponds and stelae on stone turtles, carved with the names of the country's best scholars.
Price: About 70,000 ₫
Insider tip: Go at opening time (8 am), before the school groups. In May and June graduates in gowns come here for photos: lovely and lively.

🚂 Train Street
A narrow lane where the train passes half a metre from café tables and front doors. You sit with a coffee on a tiny stool as the train rumbles past, horn blaring.
Price: Free entry; coffee at a café 50,000–80,000 ₫
Insider tip: Access keeps opening and closing: in 2026 some entrances are blocked and only café customers are let in. Ask the café owner for the train times and pull your feet and bags back as soon as you hear the signal.
