... and these are just a few of the wrecks I've dove..
I'm sure your area is nice - but it doesn't have this many wrecks and it doesn't have this kind of life. In recent years we've had everything from a Whale Shark to a Great White with a pup... a fun Bull Shark, barracuda by the hundreds, Lionfish is similar numbers, daytime octopus... roughtail and southern sting-rays with 6 foot wingspans, mola mola, and so much more...
I only made it number one because I lived close over my number two spot Truk - which was far away... but it would likely still be number one regardless.
Comparing it to so many other places - including the Barrier Reef in Australia, the Coral Sea, Central and South America, the Caribbean, the West Coast of the US and Mexico etc... NOTHING and I mean NOTHING comes close.
If you want the best diving in the world - especially for wrecks and large animal possibilities - this is it.
