The main island is Sarpan, known for its Stone Age tool finds.
[1] At just 0.45 km2 (110 acres),[1] Le Parc National des Îles de la Madeleine is the smallest national park in the world, and a UNESCO World Heritage Tentative List site.
Sarpan [fr] (Île aux Serpents), the largest of the islands, is home to breeding colonies of red-billed tropicbird, white-breasted cormorant, and bridled tern.
When French naturalist Michel Adanson explored the islands in 1749, he claimed to have found a baobab that was 3.8 metres (12 ft) in diameter, which bore the carvings of passing mariners on its trunk, including those of Prince Henry the Navigator in 1444 and André Thevet in 1555.
