It's not Orlando, It's not Miami, it's not even Jacksonville. It's a tiny little spot with decent beaches, a long history that's reasonably-well-preserved, and quiet relaxation.
The marsh that's pictured in this article (labelled "boardwalk over marsh") looks like the Bloody Marsh [0], the site of the battle that was the "last straw" for the Spanish in their attempts to claim land further up from Florida (which used to extend a bit farther north than it does today).
The colony of Georgia was chartered by Britain around this area in part as a response to that "invasion", in an attempt to protect the important British port of Charleston up in Carolina (before the NC/SC split). Of course, the other key motivation was to have a whole bunch of land to use as an alternative to overcrowded debtor's prisons, so there's that.
This is in part why Savannah (another beautiful historic coastal spot in Georgia, though a much larger one) was so significant to the state for so much of its early history: it was the first planned city in the state, as evidenced by the fact that it's home to the oldest still-standing building in the entire state (a gardener's shed built in the early 1700s, now part of a tourist-trap restaurant).
All this to say: yes, Georgia definitely has a coast, and it's worth seeing (in this HNer's opinion), and worth preserving.
