Mount Olympus is an attraction both for tourists as well as mountaineers from all over the world. It is the most popular destination among the Greek mountains with more than 150,000 visitors entering the National Park only from the east side. The National Park Service has only one checkpoint along the road that leads from Litochoro to Prionia, so the exact number of visitors is not well documented since many people enter the National Park year round and from other sides of the mountain as well.
The increasing popularity of the mountain is evident from the large number of international visitors (about 70% of the total number) resulting in the construction of totally 9 refuges since the 1950's. In additions to those refuges there are also 6 bivouac rooms located along the least popular routes.
