Nosy Iranja, often called 'Turtle Island,' is a stunning Malagasy destination known for its two islands connected by a pristine sandbar at low tide. It is almost exclusively accessed via full-day guided boat tours from Nosy Be, making solo visits impractical. The best time to visit is during the dry season, from May to November, to avoid rough seas. A typical full-day tour costs approximately €50-€100 per person, usually including transport, lunch, and activities like snorkeling. Visitors should expect a full-day excursion, often 8-10 hours, enjoying the unique sandbar, turquoise waters, and observing sea turtles; essential items include sun protection and insect repellent.
