A visit to Cu Chi Tunnels typically takes 5 to 8 hours, including travel to and from Ho Chi Minh City. This allows enough time to explore the tunnels, watch the introductory video, try cassava and tea, and check out the exhibits and traps. If you're joining a morning tour, you'll be back in the city by early afternoon—perfect if you’ve got other plans. But if you prefer a later start, afternoon tours offer the same experience with a quieter, less crowded atmosphere.
