Tassili n'Ajjer National Park in the Sahara, Algeria (© Gil Giuglio/Hemis/Corbis)

【May 6 2013】This eroded sandstone "rock forest" is just one of the curiosities you'll find in Algeria's Tassili n'Ajjer National Park. There's evidence dating as far back as 6,000 BC, that this wasn't always the desert it is today. People made their way here for many thousands of years, hunting, herding animals, and leaving behind archaeological remains, ceramics, and ancient rock art. Today, the Tassili n'Ajjer National Park is a UNESCO World Heritage natural and cultural park. Explore breathtaking Gallery from the HuluTrip homepage over the past 5 years..
