The symposium excursions include the most beautiful and famous sites of Armenia. Dilijan city is located at north-east forest site of Armenia. It is separated from the rest of Armenia by the Pambak ridge. A long tunnel connects Dilijan with the rest of the country. This resort corner of Armenia is about 1258-1510 meters above the sea level, is hidden in a canyon, and is split by the river Aghstev. The city will captivate you with a picturesque beauty and a soft climate. The key gem of the place is the Haghartsin monastery hidden in a side valley and surrounded by a lunch beach forest.

Haghartsin is an ancient monastery in Tavush province of Armenia. The monastery complex was founded in X-XIII centuries and consists of several churches of St. Gregory, Holy Mother of God, and St. Stepan. The complex is a clear demonstration of harmony between the nature and the architecture.

Sevan Lake is the only source of still water in Armenia and the largest across the entire Caucasus. Sevan is located in a kind of mountain bowl, about 2 km above the sea level, and surrounded by craters of sleeping volcanoes. Sevan is an interesting historical place. The lake shores accommodate ancient Armenian monasteries Sevanavank and Airivank, and the largest Khachkar cemetery in Noratus village.
