Isalo (Ranohira)
A Jurassic sandstone massif, with hikes through canyons to natural pools, ring-tailed lemurs around the campsites, and sunset at the Window of Isalo.
Isalo lies in the Ihorombe region of south-central Madagascar, along National Road 7, about 700 km south of the capital Antananarivo and about 240 km from Toliara on the southwest coast. At its core is Isalo National Park, a Jurassic sandstone massif of about 815 sq km, established in 1962, where wind and rain have carved plateaus, deep canyons, stone windows and strange rock formations, while the canyon floors hide palm oases, waterfalls and natural pools; it is often called "Madagascar's American West." Visitors base themselves in the small town of Ranohira at the park gate. The most classic day route takes in the Namaza campsite, the Cascade of the Nymphs, the Black and Blue Pools, and the Natural Pool. To the north, Monkey Canyon and Rat Canyon are good for lemurs; to the south, the Window of Isalo and the Queen's Rock, beside National Road 7, are where to watch the sunset; keen trekkers can camp for 2–3 days to reach the Portuguese Cave. Farther south along the road is the sapphire mining town of Ilakaka, and about 85 km to the west is Zombitse National Park, a birdwatching paradise. Climate: April to November is the best dry season, with sunny, hot days and cool nights (nights from June to August can fall below 10℃); December to March is the hot, thundery rainy season, and some dirt roads become impassable. Getting there: most people travel by chartered car along National Road 7, which takes 2–3 days from the capital and about 4 hours from Toliara. A licensed guide is required on all park routes, and tickets are priced per day. Plan 2–3 days, and take care with sun protection and hydration.
