One of my best travel adventures was traveling as a medical volunteer to Cambodia. I flew solo to Phnom Penh and from there, with the rest of the volunteers; we made our way to the health centre, which was about 2 hours away. The ride itself almost gave me a heart attack as the Phnom Penh highway is a one lane road and how they overtook cars before cutting back into their own lane when they were only barely 5 meters away from each other still thrilled me to this day.
The health centre is tucked away in the middle of a tropical jungle with plenty of mosquitoes, rambling elephants, limited electricity so much so we had to work with the patients and our way around the toilet in the dark at night, cold rain water showers even in the monsoon season and in a very simple environment with nothing but the basic necessities. Our sleeping area was a shared area with mats below and mosquito nets above. There are not even fans but being au naturale, at night we can see fireflies blinking brightly above us as we dozed into sleep creating a very beautiful and romantic sight.
