Distances In Chile Are Long
Although Chile cannot claim to be the world's longest country, it may easily be the shortest. In actuality, it is barely 180 kilometers wide on average (111.85 miles). As a result, many people wrongly believe that Chile is the world's longest country. When measured from east to west, however, Russia is somewhat longer, and Brazil is slightly longer when measured from north to south.
You've figured it out: distances are long, and domestic flights take a few hours on average (for instance, it takes roughly 3,30 hours to get from Santiago to Punta Arenas). You'll have to drive a lot, especially if you go to Patagonia, in addition to the hours spent flying. A 5- to 6-hour (beautiful) trip from the Punta Arenas airport to EcoCamp Patagonia is required!
If you're planning a trip to Easter Island, keep in mind that the "world's most distant island" is 3.759 kilometers (2.335 miles) from Santiago (a 5-hour and 40-minute flight).
