Nuclear Bunker (Berlin, Germany)
Your eyes will require some minutes so they can adjust to the dim surrounding of this Cold War bunker that is said to be radiation proof. Notice the silence of the surroundings and how creepy it is to see rows and rows of bunk beds taking most space. This bunker can house around 3,500 people and operate for two weeks given all the supplies were provided prior to a nuclear attack.
Cu Chi Tunnels in Vietnam
The Cu ChiTunnels is an underground network stretching for around 200 kilometers. The narrow trapdoor entrances are deceiving since you will find below the ground dormitories, kitchens, conference rooms, and even a hospital. The tunnels were vital to the thousands of Viet Congs who fought during the Vietnam War. They were bombed several times but the villagers below were not captured.
Aktun Chen Caves (Yucatan, Mexico)
You will love te cenotes or the subterranean rivers in these caves in Mexico. The water is crystal clear and the floors of the wells are pristine white. You can explore them by trekking or you can also scuba dive. The only word that describes the fossils, stalactites, stalagmites, and rock formation is amazing.

This is the dirty side of the City of Lights which ironically helps keep everything clean. The sewers is about 2,092 kilometers long where millions of gallons of water rush through everyday. Trekkers will learn about waste disposal with attractions ranging from aged waste disposal systems and flushers that keep solid debris out. You have to bare with the smell though of the city underneath Paris.
