Daya Chiker is a polje depression in Morocco. It is located in the Fez-Meknes region in the northeast. The climate is Mediterranean. Agriculture has been practiced since the late Neolithic period. Tourism is growing due to the adjacent Tazekka National Park.
Archaeological artifacts dating from the late Neolithic period (ca. 3800-2200 BC) have been found in Daya Chiker, indicating intensive agriculture in the area. The artifacts include handmade pottery, chipped stone, several polished axes, querns and other hand tools.
The Daya Chiker polje is located on the northern slopes of the Middle Atlas in the Fez-Meknes region, in the northeast of the country. The depression is the bed of a former lake. By road, Daya Chiker is east of Rabat, the capital, and from the city of Taza.
The Daya Chiker polje is a limestone karst formation. It is about long in the southwest-northeast direction and wide. The large flat depression at an elevation of consists of Toarcian schists, a metamorphic rock formed from sedimentary limestone strata. The flat bottom is surrounded on the east, north and west by gray cliffs consisting of hard dolomite. These are covered with open live oak forests. The peaks range between . The south side, has outcrops of Triassic clays and basalts. The flat bottom has a few low schist hills aligned along the long southwest-northeast axis.
Karst phenomena including leaching by underground streams and seasonal floods have resulted in a number of sinkholes, caves and grottos along the edges of the Daya Chiker depression. Major underground chasms are the Chiker Grotto and the Friuato Caves, located along the northwest ridge.
The Chiker cave has a depth of and a length of . At deep, the Friuato cave has a rich collection of chambers, narrow tunnels, and natural bridges, full of stalactites and stalagmites. An underground river about long flows through the cave system. It is speculated that this river connected with the Chiker cave in the past.

The Friuato Cave is one of the attractions of the Tazekka National Park, adjacent to Daya Chiker. The deep vertical entrance has concrete steps and a ramp. This leads the visitor into the system of vast chambers connected by narrow tunnels. At lower levels, the temperature is constant between and the high humidity results in condensation on the walls. A few guest houses in farms offer a rustic experience to tourists.
