The forested and reclusive town is home to numerous Armenian artists, composers, and filmmakers and features some traditional Armenian architecture. The Sharambeyan street in the centre, has been preserved and maintained as an "old town," complete with craftsman's workshops, a gallery and a museum. Hiking, mountain biking, and picnicking are popular recreational activities.
In an ancient popular legend, the name of the town is named after a shepherd called Dili. The shepherd Dili was in love with his master's daughter, however her father was against it and ordered to kill the shepherd. For many long and dark days, the sorrowful mother was mourning and looking for her only son all over the area and desperately crying, "Dili jan, Dili jan .. " ("Jan is an endearment term added to the name of a friend or family member). According to the legend the area was later known for his name.
Dilijan lies on the banks of Aghstev River with a length of more than 20 kilometres (12 miles) and at a height of 1,500 metres (4,921 feet) above sea level. The valley is surrounded with the Lesser Caucasus mountains from the north, and the Semyonovka mountain pass from the south. The mountainous areas are all covered with thick forests occupying a territory of more than 34,000 hectares (84,016 acres). Reaching up the highest peaks of the mountains, the forests turn into Alpine meadows. In addition to Aghstev River, many other tributaries flow through the town.
In 2009, it was announced by the Armenian government that Dilijan will turn into a developed financial centre for Armenia and the region. According to government officials, many of the operations and responsibilities of the Central Bank of Armenia will move the northern town-resort of Dilijan, starting from 2013.
Currently, many significant financial and cultural institutions are operating in the town such as the Dilijan regional financial and banking centre, the United World College Dilijan, the Old Dilijan-Tufenkian Centre, the modern building of Dilijan theatre and the Dilijan Museum.
