Despite being nearer to the main population centres (such as Istanbul or Ankara) of the country than central and eastern parts of the Black Sea coast, this region is remote, largely due to lack of an airport or major highways.
In ancient times, the region was known as Paphlagonia.
It's fairly easy to get in the westernmost sections of the region (around Düzce and Bolu) as they lie on the main motorway between Istanbul and Ankara (O-4/E80), the biggest Turkish cities. Getting into most other parts of the coastline involves quitting this motorway at Düzce and then heading for north to Akçakoca, where the highway meets the coastal road.
Buses to cities and some towns of the region from big cities of the country can be found.
Only Zonguldak (and a number of other towns —most notably Karabük— on the way) in the region has a rail connection with the rest of the country. But this shouldn't be taken to mean that it has lots of connections—it's served by a single daily train from Ankara.
