Witnessing the travels of migrating animals has thrilled people for millennia. Elephants, polar bears, even monarch butterflies traverse the earth in search of warmer climates or nesting grounds.
Animals undertake any number of migrations, including seasonal, latitudinal and reproductive migrations. Luckily, some of the most amazing trips are visible by even the least eager human traveler.
With the winter months fast approaching, we here at HuffPost Travel decided to take a look at some of the most awe-inspiring migrations that you can witness around the globe. Some can be experienced first hand (Barbuda's frigate bird sanctuary is truly amazing) while others are harder to reach.
Nature's most amazing spectacles are just a plane ride (or two or three) away.
