Iquitos is the biggest city in the world without any roads leading to it. To get there we had to take a three hour flight over the rainforest, and when the clouds cleared, the view from the window was pretty spectacular.
After spending three chilly weeks at high altitude, it was something of relief to land in the sweltering heat of the rainforest town of Rurrenabaque. The little 19 seater plane touched down at the smallest airport I have ever been to. Only the runway was tarmac, the plane had to taxi over grass and mud to reach the terminal building where pigs roamed freely. No such thing as airport security here.
