What to see in Vietnam
The Cu Chi tunnels are an interesting attraction to understand first-hand the recent history of Vietnam, the Vietnam and Indochina wars and above all, the Vietnamese ingenuity. To explore the complex of tunnels requires crawling in the dark through very tight and claustrophobic tunnels however they have been enlarged to accommodate tourists, although you are still likely to brush shoulders! You will have to crouch and crawl as the tunnels are extremely low. The tunnels, which are extremely humid, are unlit, so you will have to delve deep into the dark.
