As if my jet leg alone was not enough already to get me sleepless nights in Ho Chi Minh City we had to meet up in the Lobby of the Grand Hotel Saigon at 04.00 in the morning for our trip to Phong Nha-Ke Bang National Park. We were about to travel to Quang Binh Province to check out all the tourist spots in the Phong Nha-Ke Bang National Park. It wasn't my first trip to Vietnam, but it was my first time to this part of the country.
