In Isimila in the late 1950s, archaeologists unearthed one of the most significant Stone Age finds ever identified. The tools found at the site are estimated to be between 60,000 and 100,000 years old. Although the display itself is not particularly exciting, the surrounding area is intriguing, with small canyons and eroded sandstone pillars. The main pillar area is accessed via a walk down into a steep valley (about one hour round-trip), for which you’ll need a guide (small tip expected). Visits are best in the morning or late afternoon, before the sun gets too high. A small museum in which all the Stone Age finds are to be gathered is being built (entry is included in the admission price). There’s also a covered picnic area (bring your own food and drink).
