Take your pick from these 6 coolest trips.
1. Explore the Forbidden City of China
If your father loves history and ancient architecture, don't think twice - just book yourselves a flight to China. The Forbidden City, a sprawling palace complex in central Beijing, covering and area of closely 2.6 million square feet with 800 buildings and expansive palaces, is a must-see. The Zhangjiajie National Forest Park, the Temple of Heaven, the Terracotta Warrior Museum, and Dunhuang Crescent Lake are other key places that will surely interest your dad. And yes, of course, visit the Great Wall of China (that goes with saying).
