About Hangzhou

Choose May-September for this rhythm: bike the lake causeways, sip Longjing tea, and stroll broken-bridge legends. Spring mist and autumn clarity are classic West Lake moods.

Travel Tips

West Lake Morning Mist
West Lake paths and causeways are magical at sunrise before tour groups. Midday heat pushes visits toward temples and museums.
Metro & Lake Bikes
Metro reaches major hubs; shared bikes suit flat lakeside loops. Boats and causeways connect scenic spots without taxis.
Temple & Tea Fees
Lingyin Temple and some gardens charge entry; West Lake itself is free to walk. Longjing tea villages may expect purchases with tastings.
Tea Culture Courtesy
Sip slowly and ask before photographing tea workers. Summers are humid - light clothes and insect repellent help near lotus ponds.
