The Llanos del Republicano Route begins in the south of the municipality, where an enclosed valley is crossed by a river, although it only has water during the rainy season. Following its course, we reach a mountain where the river enters through a cavity. It should be noted that, if you want to enter the chasm, you will need both knowledge of caving and the appropriate equipment. To return to Villaluenga, take the Grazalema direction on the road and when you turn right at the inn, you will begin the descent to the Llanos del Republicano. In this esplanade, all the tributaries that converge in the area will once again enter another cavity, this time the Republican Chasm, which is smaller than the previous one. The route lasts 4 hours and is of medium difficulty.
