Angel Oak - Johns Island, SC - 1,400 Year Old Live Oak. Angel Oak is a live oak tree that is located in Angel Oak Park, which is on Johns Island in Charleston South Carolina. Angel Oak is significant because it is believed to be close to 1,400 years old, which could make it one of the oldest living things located east of the Mississippi River. While there are some conservative estimates that date the tree younger, most consider the tree to be 1,400 year old or older. The limbs of the oak tree crawl along in ground and up into the sky. Spanish moss can be found hanging from the tree. Angel Oak is 65 feet tall and has a circumference of 25.5 feet.
