Isalo National Park
A ruined sandstone massif set upon the savannah, oasis-canyons where you swim beneath the pandanus: Isalo is the Malagasy Far West — and the RN7's great mineral finale.
Suggested stay — 2 nights
After hours of highlands, the landscape snaps open: Isalo raises its Jurassic sandstone ramparts, eroded into towers, arches and organ pipes above the blond grass. You hike it on day trips from Ranohira: the Canyon des Makis and its gallery forest where sifakas and ring-tails leap, the natural pool — an emerald basin fed by a waterfall, guarded by a crown of pandanus — and the ridges of the Namaza circuit where Bara tombs nest in the faults.
The evening ritual never changes: Isalo's Window, a sandstone arch that frames the setting sun a few kilometres from Ranohira. Heat is the massif's true adversary — expect 30-35 °C by mid-morning in the dry season: walk early, swim at noon, admire at dusk. Two nights allow one full day inside the park and the luxury of a sunrise on the ramparts.
Don't miss
- The natural pool + Canyon des Makis loop, the classic day and the best one
- Sunset at Isalo's Window, arriving 45 minutes ahead of time
- The Cascade des Nymphes and the Namaza canyon for strong legs
- The 'dancing' Verreaux's sifakas in the gallery forest, early morning
Our tips on the ground
- Start walking by 7 am at the latest: the sandstone radiates like an oven from 11 am and shade is scarce on the plateaus — three litres of water per person, a hat, and the swim as the midday reward.
- Don't roll up to Isalo's Window at the last minute: the site is popular, so come early and explore the surrounding boulders for a crowd-free foreground.
- In Ilakaka, the sapphire town on the Tulear road, drive through without stopping with valuables on show: the workshop visits, genuinely interesting, are done accompanied by your driver or a local contact.

Before you go
Readers' questions about Isalo National Park
Do you need a guide to hike Isalo?
Yes — the guide is compulsory, as in all Malagasy national parks, and is hired at the park office in Ranohira (allow 100,000-150,000 Ar per group for the day, plus the 65,000 Ar entry per person). Good value: the guides know the shade timings, the pools worth swimming and the sifaka trees.
How long from Isalo to the coast?
Allow 4 to 5 hours on the RN7 to Tulear, crossing Ilakaka and the Mahafaly plateau. Many end the circuit on the beaches of Ifaty or Anakao north and south of Tulear — two well-earned rest days, bottle baobabs and turquoise lagoon, before the flight back to Tana.
