Isalo National Park is a high sandstone massif in the south of Madagascar, where wind and water have carved ridges, canyons and rock windows out of the red and gold stone. Walkers follow guided trails down into green canyons with natural swimming pools, across open plateau and to viewpoints that glow at sunset. The park is a typical stop on the long RN7 road trip, which runs from Antananarivo through the central highlands to the dry south, and the nearby village of Ranohira acts as a gateway with lodges and restaurants. Shorter routes take half a day, while longer circuits last several days with camping. Ring-tailed lemurs and other wildlife can be seen on some trails, though sightings vary. The landscape feels like another country after the rainforest, with grass, rock and wide skies.
Reaching Isalo is part of the experience. The RN7 road trip takes several days from Antananarivo, stopping at highland towns and parks along the way, and most travellers book a multi-day tour. The tour featured here is an RN7 adventure that heads towards Isalo, so check the exact route, length and inclusions with the operator, including park fees, guides and meals. Domestic flights to the south shorten the journey but are a separate arrangement.
On the trails, visits are normally made with a park guide, who explains the geology and wildlife and keeps you on the paths. Routes vary from easy half-day canyon walks to longer circuits, and the heat on the plateau can be strong, so carry water, wear a hat and sturdy shoes, and start early. The natural pools are popular for a swim, though water levels depend on the season. Sunset at the rock formations is a favourite activity, and a torch is useful for the walk back.
Season notes
The rainy season begins around November, and the south sees storms in the following months, which can make trails slippery and canyons swollen. The drier months are generally more comfortable for walking. Phone signal is patchy, lodges can be simple, and distances are long, so build in spare time. Check the weather and ask your guide about conditions before choosing a route.
