Almost everyone who visits Israel with a tour group makes a stop at Qumran. The guide gets a commission when you buy Ahava beauty products! But that’s o.k. Also, everyone who wishes listens to the story of Qumran and the discovery of the Dead Sea Scrolls. Most folks get a photo of Cave 4 where many of the fragments of biblical books were found.
There are other caves in the area where important scrolls were found. Todd Bolen has written an informative post, especially about how to locate Caves 1 and 2, at the Bible Places Blog here. He even includes a PDF file so you can print the material and carry it with you on your next trip to Israel.
