- The Window (La Fenêtre de l’Isalo): A natural arch in a sandstone outcrop, worn through by wind and water. Walk to the base and the opening frames a clean slice of sky and the plain beyond. The rock is rough, pale and grippy underfoot, and the arch is bigger than photos suggest.
- Sunset through the arch: This is what most visitors come for. In the last hour of daylight the stone shifts from tan to burnt orange, then to a dusty pink. Expect other groups jockeying for the classic silhouette shot, so claim a spot early and stay put once the sun is low.
- The Isalo sandstone massif: The surrounding rock is carved into ridges, towers and gullies that look sculpted. From the high points near the Window you read the layered cliffs and valleys clearly, and the fine red-gold grit blows into every crease

- Elephant’s foot and aloe plants: The thin, dry soil supports plants that look odd to a first-time visitor. The swollen-trunked elephant’s foot grows from cracks in the stone, and spiky aloes dot the slopes. Your guide can point out which plants are endemic and which are common here.
- Lemurs and birdlife: Verreaux’s sifakas and ring-tailed lemurs live within the park, and sightings along the approach are possible rather than guaranteed. Listen for rustling in the scrub and look for pale shapes bounding through the trees. Raptors often circle the cliffs near sunset.
