Djanet, Algeria, serves as a gateway to the stunning Tassili n'Ajjer National Park, renowned for its prehistoric rock art, dramatic sandstone formations, and vast desert landscapes. A visit typically involves guided tours as independent travel is highly discouraged due to safety concerns and the need for local expertise. The best time to visit is during the cooler months (October to April) to avoid extreme heat. Be prepared for rugged terrain and limited accessibility for those with mobility issues. Costs can vary significantly depending on the tour operator and length of stay, but expect it to be relatively expensive due to the logistical challenges of desert travel. A typical visit duration ranges from a few days to a week, allowing for exploration of different areas within the park. Always prioritize booking through reputable and officially recognized tour operators to ensure safety and responsible tourism practices.
