This place is not "state of the art" or fancy, but I challenge you to find another place on earth, for $2, where you can see such a deadly collection of venemous snakes anywhere on earth.
"Snake", the founder, is a wonderful resource and his love of snakes and passion for educating local villagers about the ecology of snakes has led him to create Uganda Reptile Village. His hope is to educate villagers about the role that snakes play so they will stop automatically killing any snake they see.
Elementary schools take field trips to Uganda Reptile Village. Snake also offers to help with snake removal should local citizens find an unwanted reptile in their house or on their property.
All in all, a great place to support.
