It stretches over the slopes of several mountain ranges. Among them are the mountain ranges of Pambak (Lori province), Areguni (Gegharkunik province), Miapor (Tavush province), Ijevan (Tavush province) and Halab (Lori province). Interestingly, only those parts are included which fall on 1070-2300 meters above the sea level. In this regard, the mountain meadows above the mentioned altitude do not make up part of the park.
The park covers a territory of 24,000 ha. It has been renowned for its forest landscapes, biodiversity and mineral water springs, which are thought to have curative and healthy traits. The park was established in 2002. In the territory on which the park was established there was formerly the state nature reserve founded in 1958. On the whole, the territory was neither enlarged, nor reduced; it was only a matter of change of status – from reserve to national park. The change of the status had its own reasons, which could not be ignored or avoided. Among such reasons are the Yerevan-Ijevan railway, which passes through the park, the commercial activities, the presence of settlements, and after all, the city of Dilijan itself.
The park offers diverse flora and fauna. But it’s not only that. While walking around you will see the various mountain ranges in which the park seems to be embraced, as well as the River Aghstev flowing from Pambak mountain range, beautiful Parz Lich (Clear Lake) and Tzrkalich (Leech Lake). The park also encompasses some of the most beautiful and remarkable Armenian monasteries and churches, among which are the monasteries of Haghartsin, Goshavank, Jukhtak and Matosavank and the Church of Akhnabat.
