What is your dream place to visit in your life time?

I would really like to visit Serengeti ecosystem in Africa.  This is a geographical area in northern Tanzania.  It witnesses the largest mammal migration wherein around 1.5 million wildebeest and 300000 zebras cover Tanzania’s Serengeti plains.  They travel a distance of around 18000 miles in search of food and water.  It is really a feast to the eyes. It is considered as one of the natural wonders of world. It is a magnificent view when the herds gathered to cross the Grumeti River and Mara River from July through September.

I wish if I could witness this great event once in my lifetime. What is your dream location?
