This is a trip (my second trip) to the mexican waters of Revillagigedo Archipelago. Four islands located 24h boat from Cabo San Lucas, Baja California. If the Wildlife is interesting, and can be sometimes very rewarding (jacks, sharks, dolphins, whales), the main attraction are the giant manta rays.
This is truly a unique spot in the world where the interaction between the animals and the divers are so obvious, and for most of the time.
This is a incredible experience there to dive with thoses quiet giants, the most beautiful show underwater by far.
