Cozumel Highlights
Teardrop-shaped Cozumel has seen some hard times - Spanish invasion, death by smallpox and a flailing economy - but these days it is a calm, charming island with a prime diving reputation. Known as Ah-Cuzamil-Peten (Island of Swallows) by its earliest inhabitants, it is Mexico's largest and most populated island.
In its new incarnation as one of the world's most sought-after diving destinations, Cozumel has gone through something of a growth spurt. The islanders now number over 75,000.
