The second part of my trip was spent Scuba diving.  I spent four days in Taganga with Poseidon Dive Center.  It was fantastic.

I did the following

• Deep diving to almost 40 meters
• Drift diving where you just drift with a current
• Night diving where I saw crabs fighting, giant colorful lobster, and fish sleeping in the water
• Regular diving where I saw fish of every color and tons of clams, moray eels, etc

The water was about 75 degrees which was perfect for me for skin diving.  Every day I dove Nitrox so I never felt tired afterwards.

I also got my Advanced Open Water PADI certification, so that was nice.
