The village is home to two different interconnected karstic limestone caves with stalactite and stalagmite formations.

Rehans cave (Arabic: مغارة الريحان) is the smaller of the two and was discovered by a local at the end of the 1930s. It was only in 1951 that the local villagers were able to fully visit the cave, discovering its naturally carved statues, multiple rooms, passages and, of course, its beauty. It is widely known as Jeita of the south for its resemblance to the Jeita Grotto.

Recent Topography showed that the cave is approximately 185 m long. Although very inviting for the locals, they cannot go further than a 110 m since they are mal equipped and air and light become very scarce.

It is believed to be connected with the second and larger winter spring cave but there's no evidence of this claim yet.

The winter spring cave (Arabic: مغارة نبع الشتوي) is a 4.1 kilometers long cave found in what is called Khazem's Tract (Arabic: خلة خازم). Discovered in 1956, it is the 4th largest cave in Lebanon and the biggest of South Lebanon.
