Since Trun is near Bulgarian-Serbian border, just 19km aways from Serbia the whole area was wth very restrictive access at the time of the socialist era in Bulgaria. That's why Trun region has very clean nature.
The building of the Trun Eco-Trail started in 1997 and this is the first eco-trail ever built in Bulgaria.
Initially the eco-trail lead the tourists just to Erma River Gorge but nowdays the eco-trail is 13.2 km long and one needs at least 8 hours to walk the whole trail. If you are going to walk the whole trail it is recommended to hire a guide (ask in Trun tourist information centre a day or two in advance).
The eco-trail has two starting points - from the village of Lomnitsa (Erma River gorge) and from the village of Bankya famous with hot mineral springs.
Starting from Trun, or more precisely from the village of Lomnitsa, you may leave your car, walk about 5-10 minutes to rach Erma River gorge, cross the river through a woden bridge and then pass through a tunnel, digged in the beginning of the 20th century for a railway project which was never completed. Not far after the tunnel the eco-trail goes down to the river, crosses it and there after about an half hour hiking Manastirishteto rock, passing by remains of ramparts from the time of Caracalla,you will reach a terrasse with a nice panorama view.
If you continue walking on the path instead (after the tunnel ) you will pass another smaller tunner and reach the village of Bankya.
Beside the Erma River Gorge the eco-trail let you see also Yablanitsa River Gorge.
You can see the monument in memory of officers and soldiers fallen in Serbo-Bulgarian war on the main square in Trun.
After the liberation of Bulgaria in from the Ottoman yoke as a result of the Russian-Turkish war in 1887-1888 and Treaty of San Stefano (March 3, 1878 - that's why March, the 3rd is the National holiday of Bulgaria) proclaims Bulgaria as an autonomous, self-governing tributary principality.
But the Treaty of Berlin (June 13-July 13, 1878) revisited the Treaty of San Stefano to prevent establishment of Great Bulgaria with Russian infuence and splitted Bulgaria into three parts with totally different status - Principality of Bulgaria, the autonomous province of Eastern Rumelia and Macedonia remains in Ottoman Empire. The Berlin congress gave an official birth of so called Macedonian Question.
On September, 6 1885 Eastern Rumelia proclaim Unification of Bulgaria without the approval of the Great Forces. The Austro-Hungarian Empire induced the Serbians to attack the fledgling Bulgaria and the Serbo-Bulgarian war began. It is known also as the War of the Captains since Bulgaria didn't have officers above the rank of major. The most decisive battle was the battle of Slivnitsa. Bulgaria won the war. No territorial changes were made as the result of the war but the Great Forces acknowledged the Unification of Bulgaria.
The main tourist destination in the are is the Erma River Gorge.
Erma River Gorge is situated about 5km away from the town of Trun. It is 100m long and 5 m wide at the most narrow part where Erma river flows between the rocks Zhilav kamak and Curkvishteto.
There is a legend related to Erma River Gorge: Once upon the time there was a beautiful young woman Mara. She fell in love with the handsom guy Rangel. She was rich but he was very poor and because of this Mara's mother disliked him. The young couple decided to run away. But the Mara's mother curse reached them, the mountain splitted in two parts (the rocks Zhilav kamak and Curkvishteto) and both of them remained separated for ever. (Source: Stoyancho Miloshev)
