You guys should include Aqua Connections in your Saipan dive center list... I have been a long time customer and in my opinion they are the best in the island.
I swim with whale sharks every year and I always use the same company Ocean Tours Mexico:
It really is one of the best spots in the world to swim with hundreds of whale sharks in clear blue water, not to mention the manta rays and whatever else decides to turn up.
What are the chances to see whales, rays, sharks towards the end of April? If low, can you recommend another area in the region accessible from Mexico City (travelling with three young children).
Are they any dive centers that take out people who have never scuba dived before? My wife and I will be visiting Cancun for a week and would love to try to scuba dive for the first time. We both have snorkeled in the Bahamas and in Hawaii and love the water. She is a stronger swimmer than I.
Any suggestions who we can contact to brake in two virgins?
I have been to Revillagigedos 3 times and in my opinion March is the best time to go. During my two trips in March I swam with whales 4 times and saw them multiple times passing close to the boat. The giant manta rays are extremely friendly, on a few occasions I had to duck my head so that the manta did not make contact with me. My last trip in Jan we saw dolphins on almost every dive including a huge pod of 20+ members at Roca Partida. In terms of sharks I saw silkies, Galapagos, silver tip, white tip, and hammer heads... still waiting for my tiger shark encounter. Apparently there is an 18 foot tiger shark that occasionally makes an appearance.
For me Revillagigedos (Socorro) is “the” location for actual encounters with animals not just passing glimpses.
I'm going to La paz in jan-feb. I wants to dive with the hammerheads. Is it a good spot for it, I mean is there a good chance or are they actually rare there?
