Cu Chi tunnels located in Vietnam, it was about 2 hours from the District 1 in Ho Chi Minh City. Cu Chi Tunnels is an underground space. This Tunnels developed by Vietnam Army's to defend their homeland. This area is located in the forest, so the enemies could not reach the places.
While the war happened, the tunnels were used not only as a hiding place, even as a wedding and honeymoon rooms. I felt so amazed when I heard the story about the struggle of Vietnam Army's.
I even had the chance to get into the tunnel, but it just like sauna rooms, hard to breathe and space was so tiny. So, I gave up and went out from the tunnels.
If you want to go here, better you go with the travel, it will make you safe.
