Occupying pride of place in the northwestern reaches of the country, the Tsodilo Hills towers above the plain that surrounds it. The four hills are named 'The Male', 'The Female' and 'The Child' respectively while the last is unnamed. In addition to the beauty of the hills, a visit to Tsodilo is worth the time due to the many rock paintings contained within the landscape. Believed to have been etched by Bushmen, the area is home to an impressive 500 painting hubs and is thus considered one of the world's largest art sites. Some of the area's best-loved ancient artworks are found in The Female hill. As a free attraction, all visitors can explore the Tsodilo Hills every day of the week.
