On the banks of the Danube, the ancient Greek port town of Tulcea might be considered the gateway to the Delta; although there's nothing in the town itself that should detain you, you're likely to pass through en route to destinations in the Delta proper. The fastest way to get to Tulcea from Bucharest is by plane; in 2008 Tarom began flying between Bucharest and Tulcea on Sundays and Thursdays (35 min.), and there are plans to increase the volume of flights in the future. Alternatively you can catch one of two daily InterCity trains; the journey is 4 hours (although at the time of writing this was actually 7 hr. due to railway works). Tulcea's train station, Strada Potului (tel. 0240/51-3706), is right near the bus station (tel. 0240/51-3304), which is attached to the Navrom ferry terminal.
Tulcea hosts the Danube Delta Research Institute, Str. Babadag 165 (tel. 0240/52-4550; www.indd.tim.ro), useful if you're after hard facts about this unique biosphere. Tulcea is also home to the Danube Delta Biosphere Reserve Headquarters, Str. Portului 34A (tel. 0240/51-8945; www.ddbra.ro), which hosts the Information and Ecological Education Centre (tel. 0240/51-9214; www.deltaturism.ro), which can provide you with local and delta-related information; staff can also help you with accommodations, but note that they're only open weekdays.
