Lots More Information to Come
Cindy Miller Hopkins, one of our tour leaders, will be sending out lots of packing and equipment information to all participants very soon. She has been to the Galapagos several times already. I believe both systems are represented in our leaders - Nikon and Canon, so you will get some specific equipment recommendations according to your system. She does tell me that no flash is allowed anywhere in the islands, above or below water. I have also read recommendations to take a long-reach macro lens.
We at the Foundation are very happy you are on the trip, and I will be joining you as well.
