The easiest way to answer this question is to divide the different areas according to geographical location, namely north, south, east and west. We already touched on the east, or the "green corridor", referring to the extensive rainforests covering most of this landmass.
Nosy Boraha, or Île Sainte-Marie, is an island off Madagascar's east coast and worth mentioning. It's also commonly known as Pirate Island, said to have been home to over 1,000 pirates between the 17th and 18th century. This is the best seat to watch the annual humpback whale migration between June and September.
The northern part of the island, where the forest meets the beach, is the most commonly visited area on the island as it’s the most commercial compared to the other areas on the island. The north is also known for its beaches and year-round pleasant weather – making it the ideal place for kite surfers and divers. Nosy Be, Madagascar's premier tropical island destination, is also off the island's north and where you can experience the whale shark migration.
The south of Madagascar is beautiful, but as it’s so far from everything else, very few travellers choose to visit. Fort Dauphin (Taolagnaro) is a seaside town that emerges after a long drive through the spiny forest of cacti – but the journey is worth it! If you’ve ever wanted to see a carnivorous plant, be sure to visit the Berenty Reserve or take a dip in one of the many natural cascades in Nahampoana Reserve.
The western sector of the island is extremely remote, and much of it is still undiscovered, which is the selling point for the more adventurous traveller. Tsingy de Namoroka National Park is home to the unusual geological rock formations known as the tsingy formations. Road conditions are not ideal for getting here, and it's only open during the dry months between April and October. But, if you're up for the adventure, it's sure to be an incredible one! The famous "Avenue of the Baobabs" is also on this area of the island.
