While Zugdidi is not a very popular city with tourists for itself, many pass through it on their way up to Mestia in Svaneti. It does have a few things to see, though, and is located near a national park. It is also a get-in point to Abkhazia (via Inguri dam).
Trains run to Tbilisi and all stops on the way. Night trains are also available, and are the most popular way to get from Tbilisi to Zugdidi, since the marshrutkas to Mestia are coordinated with them. Arrival in Zugdidi is at 5:30AM. Marshrutkas and buses are also available to most major cities in Georgia.
