Visitors flock to Siwa: Egypt's hidden oasis threatened by tourism

Until 1984, there was no road connecting the oasis of Siwa and its 8,000 Bedouin residents with the rest of Egypt. Lost deep in the desert near the Libyan border, the country's most remote oasis was long unknown to tourists. But over the past decade, videos of visitors floating in turquoise salt lakes, climbing the 13th-century citadel or wandering through palm groves have flooded social media.
