Yes, taxis in Chengdu operate 24 hours a day, providing a reliable transportation option throughout the night. While public transit like the metro typically closes by midnight, official taxis are readily available at designated taxi ranks, major landmarks, airports, and train stations, or they can be hailed directly from the street. For added convenience, the ride-hailing app Didi Chuxing also functions around the clock, allowing travelers to book rides or make advance reservations even in the early morning hours. It is important to note that Chengdu taxis apply a late-night surcharge for trips taken between 11:00 PM and 6:00 AM, with the base fare increasing to approximately 9 or 10 CNY depending on the vehicle type. During these hours, travelers are advised to use official metered cabs or licensed ride-hailing services to ensure a safe and fairly priced journey.
