Cuisine

Local specialities include a sweet made of hazelnuts (which grow in abundance here) and an eau-de-cologne with the scent of grass. One feature of Bolu dear to the local people is the soft spring water (''kökez suyu'') obtained from fountains in the town.


Media

Bolu is home to 12 local newspapers published in the city centre, two local TV channels (Köroğlu TV and Abant TV), three local radio stations and six local magazines.


Economy

Bolu is a busy market town rather than a large city. It has one long shopping street and an attractive forested mountain countryside. Students from the university and soldiers based in Bolu make an important contribution to the local economy, which traditionally depended on forestry and handicrafts. Market day is Monday, when people from the surrounding villages come into town for their weekly shop. The main road from Istanbul to Ankara used to cross Bolu mountain, although more people would stop at the roadside restaurants than actually come into the town, and anyway now the Mount Bolu Tunnel is open most people will rush by on the motorway rather than climb up into Bolu, especially in winter when the road has often been closed due to ice and snow. Some of the service stations on the mountain road have already announced their closure or moved elsewhere.
