Isalo National Park

Madagascar's dramatic sandstone canyons and endemic wildlife

Madagascar's Isalo National Park feels like stepping onto another planet. These towering sandstone formations have been carved by wind and rain for millions of years, creating a landscape of deep canyons, natural pools, and rock formations that photographers dream about. But this isn't just about the scenery. The park shelters lemurs you won't find anywhere else on Earth, plus a surprising variety of plants that have adapted to this harsh, beautiful environment. Located in Madagascar's central highlands, about 280 kilometers south of Antananarivo, Isalo covers 815 square kilometers of some of the island's most dramatic terrain. The park opened in 1962, and while it's gained popularity with international visitors, it still feels refreshingly untouched compared to other safari destinations.

We're working on adding amazing itineraries for Isalo National Park. In the meantime, try the app to create your own!

Isalo has three main circuits, and you'll need a local guide for all of them – it's mandatory and honestly, you'd get lost without one. The Namaza Circuit takes half a day and hits the natural swimming pool at Piscine Naturelle. This is the easiest option, perfect for families or anyone wanting a taste without the full commitment. The Malaso Circuit is the full-day adventure, covering about 16 kilometers through deep canyons and ending at Piscine Noire. Expect some scrambling over rocks and a few steep sections. The Canyon des Rats circuit is the shortest at 2-3 hours, but don't let that fool you – it includes some technical climbing and narrow ledges. Most visitors combine circuits over 2-3 days. The trails aren't well-marked, which is why guides are required, but they know every shortcut and the best spots for wildlife sightings.
