The marvels of nature and the genius of medieval Arab military architecture have given north Jordan two of the most important ecological and historical attractions in the Middle East the sprawling pine forests of the Ajloun-Dibbine area, and the towering Arab-Islamic castle at Ajloun that helped to defeat the Crusaders eight centuries ago. Both these natural and man-made marvels, along with other attractions in the north, are being carefully protected to form the core of a pioneering Eco-tourism project now being implemented with French technical assistance, which aims to preserve the large pine forest that stretches from Ajloun towards the north; this is a unique environmental resource, for it is the southernmost complete pine forest in the world.

The area's cool forests, beautiful picnic areas, and extensive walking trails already attract visitors throughout the April-October season, especially from the Gulf and other warmer regions of the Middle East.

Ajloun Castle, more formally known as Qalaat er-Rabad, is the major ancient site within the Ajloun forests region. It towers above the green hills and can be seen from many miles away, betraying its strategic purpose as a military watch post that protected the trade routes in the 12th –15th Centuries. It was first built in 1184 by the nephew of Salaheddin (Saladin), Izzeddin Usama Munqith, to repel the Crusader threats to north Jordan (the Crusaders had already occupied south Jordan, from their massive castles at Shobak and Karak, and were driven out of TransJordan in 1189).

From the top of the castle, visitors enjoy panoramic views into the Jordan Valley and throughout the highlands of north Jordan. Excavations have recently identified a church that was built on the castle site in the earlier Byzantine period, while restoration and conservation works have made all areas of the castle accessible and safe for visitors. New restaurants and hotels in the immediate vicinity of the castle make it easier for visitors to spend an entire day, or a weekend, in this enchanting region. Other nearby sites that can be visited include the birthplace of the Prophet Elijah at nearby Listib, the Church of St Elijah at Khirbet Mar Elias.
