It's all temporary first of all.
Whoever said that there aren't many choices left for sites to dive...I beg to differ. Only 4 1/2 (the wreck is part of Chankanaab) of over 30 sites are closed. Las Palmas, Punta Tunich, San Francisco, Santa Rosa, Cedral, Delila, Francesa, Palancar gardens, Palancar Horseshoe, Palancar Caves, Palacar Bricks, Columbia, Columbia Deep, Punta Sur, Maracaibo, Chun Chacaab, San Juan, Barracuda, etc. I might also add that you can dive some of these reefs everyday and it won't be the same or you can dive different sections of it and not even realize you are on the same reef.
This is to allow a more rapid recovery to these sites since they were the most severely damaged. The fact that we have had less divers on the reef in the past month and will for the next few months, will also help speed the recovery.
My source is directly from the marine park, from a memo that was sent out to all dive shops. I hadn't seen some of this info in the memo's I have received, so I just called the marine park directly to confirm all of this:
Here is what I was told today at 2:05pm CST
Reefs currently "closed" (time frame not yet determined):
Paradise
Chankanaab
C-53 Wreck (for safety reasons)
Tormentos
Yucab
The recommended reefs are in fact the least damaged, but others are also lovely dives. We have dove Columbia, Columbia Deep, Palancar Bricks, Palancar gardens, Francesa, Cedral, Delila, San Francisco, and Las Palmas so far. All have been really nice dives with tons of marine life.
Camera Use:
A distance of 3 meters must be maintained between the diver and the reef. The divemaster is responsible for making sure his/her divers are respecting this rule and CAN and SHOULD restrict camera use for those who do not have proper buoyancy control or who do not respect the distance rule. It is a big distance for most shots, but hey...it's temporary!
Night dives:
The typical night dive sites are closed, therefore night dives are now limited and restricted. However, sites that are open and suitable for night diving are Villa Blanca (not in the marine park) and Las Palmas. Sites further south are too far most of the time for night diving and currently, considering that there are no hotels open down south, and most likely no other boats doing night dives in the south, I would not take night dives further than las Palmas at this time for safety reasons alone. Again, the 3 meter rule applies, which almost defeats the purpose of a night dive.
