Al-Masjid Al-Haram, literally "the Forbidden Mosque", is one of the three most sacred mosques in Islam, along with An-Nabawi in Medina and Al-Aqsa in Jerusalem, and also the largest in the world. Every year millions of worshippers visit the mosque on their Hajj pilgrimage to perform the Salah, "the act of worship”, and the Tawaf, which consists of seven circular walks around the Kaaba, the sacred building that contains the Black Stone.

Cyclists are welcome in these inland sand dunes, on the beautiful wide cycle paths or on the mountain bike trail, but the park is especially suitable to explore on foot or with a dog, if kept on a leash. With the help of the marked hiking routes you can explore the area on your own. It is advisable to bring a walking map so that you do not get lost! For mountain bikers, unpaved bike paths and routes have been set out and horse riding is possible on the marked riding trails (and free riding over the sand). Mountain bikers and riders need a permit, available at Natuurmonumenten, the surrounding catering establishments and riding schools.
