A sandstone massif carved by wind and water, with deep canyons, arid plateaus and natural pools.
Located in the Ihorombe region of south-west Madagascar, Isalo National Park is known for its dramatic eroded sandstone scenery, quite unlike anywhere else on the island. Deep canyons, sweeping plateaus and oddly shaped rock formations make it one of Madagascar's premier hiking destinations.
Ihorombe region, along the RN7 between Fianarantsoa and Toliara.
April to October, dry season, ideal for hiking.
About 700 km / 10–12 hours by road from Antananarivo via the RN7, or fly to Toliara and drive.
At least 2 days to cover the main hiking circuits.
The hike to the Natural Pool and the Blue Pool lets you cool off in fresh-water pools tucked into the canyons, after a few hours' walk under the southern Malagasy sun. The Isalo Window, an iconic rock opening, frames one of the country's finest sunsets. More experienced hikers can push on to Canyon des Makis and Canyon des Rats, home to ring-tailed lemurs and Verreaux's sifakas.
The park also holds Bara cultural sites, including traditional tombs set into cliff faces, visible from certain trails.
Isalo must be visited with a licensed guide, bookable at the park entrance. Bring plenty of water, a hat and sunscreen — the trails offer little shade at midday. Nights can be cool in the dry season, so pack a warm layer if you're camping nearby.
Continue along the RN7 to the Avenue of the Baobabs, or head back to Ranomafana for the rainforest.
