This 10 kilometer square island is a delight.
A three- kilometer -high plume erupts from the Popocatepetl volcano, east from Mexico City.
It is the longest designated trekking trail of it's kind in the world and takes the adventure trekker on a 5330 kilometer journey from Cooktown.
It is less that half a square kilometer, and although it's population is less that 1000 people, it gets almost 4 million visitors per year.
This would charge each person per kilometer driven.
