Today was another jammed packed, amazing day.  We started in the early morning looking for land iguanas on Isla Plaza.  We were successful in finding plenty within the cactus forest.  Then we travelled for a few hours to Puerto Ayora, Santa Cruz where we visited the Darwin Research Station.  Puerto Ayora is the largest city within Galapagos with 20,000 inhabitants.  Santa Cruz is one of 5 inhabited islands.  At the research station we were able to see Lonesome George, a land tortoise that is 150 years old.  His name is Lonesome George because he is the last of his species.  Scientists have tried to mate George with a similar species without any luck.  These tortoises are enormous and look so ancient.  Towards the end we were able to get up close and personal with a handful of them to admire their size and uniqueness.  In the afternoon, we walked to Tortuga Bay which had a beautiful beach.  From there, we were free to shop within the city and return to the boat for dinner.  The crew kindly allowed us to go back to the city after dinner if we so chose.  Here are pictures from the day:
