The autumn is unusually sunny and mild this year – a great occasion for walks in nature.

Forest Park "Kenana" near the town of Haskovo enjoys great interest among tourists because of the recently opened educational eco-trail dedicated to the Bulgarian khans and tsars of the First Bulgarian Empire (from 681 to 1018) and the Second Bulgarian Empire (that lasted until 1396).

• Ivan Assen II, the Tsar that unified the Bulgarian lands

• Bulgarian statehood has millennial tradition

The route is 5-km long and takes tourists to the place where the Battle of Klokotnitsa is supposed to have taken place. There are information boards along the entire trail that tell about the history of Bulgaria from the time of Khan Kubrat to the last Bulgarian ruler before the fall of the country under Ottoman rule - Tsar Sratsimir. Each sign has a QR code that links to a special webpage. From it, visitors can learn more interesting details about the glorious Bulgarian rulers.

The eco-trail was built by the Rotary Club with the assistance of the municipality of Haskovo.
