The Spiny Forests of Madagascar

Some places reward you with beautiful scenery, while others spark curiosity and bring you new knowledge that deepens your perspective on the world.

The spiny forests of southern Madagascar do both. Here, bizarre plants thrive in an unforgiving landscape, acrobatic lemurs leap between thorn-covered trees, and some of the world’s rarest creatures eke out a seemingly impossible living in a harsh environment characterized by heat and drought. Beyond the wildlife, encounters with the local Antandroy people offer a window into traditions shaped by ancestor worship, community ties, and an enduring connection to the natural world.

Madagascar’s spiny forest is the perfect place for curious travelers who appreciate genuine discovery, warm hospitality, and the pleasure of exploring a place few visitors will ever seek out. We have been twice over the past ten years, and cannot recommend it enough as part of a comprehensive Madagascar experience.

Madagascar’s spiny forests are a distinctive dryland ecosystem found in the island’s arid south and southwest, where scarce rainfall and poor soils have shaped extraordinary adaptations. The landscape looks almost otherworldly, with spiny plants that resemble cacti (though they are not closely related), strange octopus trees that reach for the sky, and a remarkable diversity of euphorbias and other drought-resistant plants. Around 95% of the plant species in this ecoregion are endemic to Madagascar, making it one of the island’s most botanically distinctive environments.

The best way to experience the spiny forest is on a nature walk, accompanied by a local naturalist guide. A flash of sudden movement might reveal a Verreaux’s sifaka leaping between trees, or a ring-tailed lemur scurrying about on the ground, peering up at you with its intense amber eyes. Slow down and look a little closer, and the smaller wonders emerge: a perfectly camouflaged chameleon, an endemic bird darting through the thorny scrub, or, if you are really lucky, a critically endangered radiated tortoise lumbering slowly across the forest floor. The spiny forest shelters wildlife found nowhere else on Earth, and every walk you take will delight and surprise you with new discoveries.

After dark, the spiny forest takes on an entirely different character as you explore under the light of the moon. Flashlights reveal the twisted silhouettes of octopus trees and catch the reflective eyes of creatures almost impossible to spot by day. White-footed sportive lemurs emerge, tiny mouse lemurs scamper through the trees, and sleeping birds, geckos, and chameleons become unexpected discoveries in the dark. The eerie silence of night is punctuated by the occasional hoots, peeps, and clicks of nocturnal wildlife, while your guide reveals a hidden world that most visitors to Madagascar never get to experience.

The spiny forest is also the homeland of the Antandroy, whose name is often translated as “people of the thorns.” Local life offers a fascinating perspective on the relationship between people, place, and tradition: zebu cattle remain important symbols of wealth and social standing, wooden plank houses reflect highly localized building practices, and ancestral tombs hold deep cultural significance.

You may see cattle being driven to market or learn about fady, the customary taboos that shape everyday life throughout Madagascar. Among the Antandroy, traditional prohibitions against killing radiated tortoises have helped protect a species threatened elsewhere by illegal hunting. Learning about these customs with a local guide adds a human dimension to the landscape, reminding us that this is not simply a wilderness to explore, but a place with its own history, beliefs, and living, evolving culture.

For all its remoteness, southern Madagascar offers a particularly rewarding kind of comfort. At Mandrare River Camp, a small tented camp tucked beneath tamarind trees beside the river, days unfold around guided wildlife walks, cultural visits, and unhurried time in nature. Return from the forest to excellent meals and warm hospitality, cool off in the pool, or settle onto your tent’s private deck with a book and views overlooking the Mandrare River.

One of the highlights of staying at Mandrare River Camp is a sunset excursion to a secluded stand of baobabs that is far superior to the over-touristed Avenue of the Baobabs near Kirindy. At Mandrare, you will have your own, private Avenue of the Baobabs, where these towering giants frame the ever-changing light and sundowners give way to dinner beneath the stars. Traditional Antandroy music and dance complete the evening. Thoughtful comforts, personalized service, and extraordinary experiences in a place that still feels far removed from the usual tourist trail make this one of our favorite spots on the entire Eighth Continent.

The spiny forest is among Madagascar’s most threatened ecosystems. Habitat loss, including the harvesting of trees for charcoal, puts pressure on wildlife and the communities that depend on the land. Responsible tourism can help create an alternative by giving forests and their wildlife tangible value to local people. At Mandrare River Camp, community-led conservation efforts include protecting sacred forests, supporting reforestation, and developing alternatives to traditional wood-fuel use. Visits also generate income for local guides and communities, many of whom have few economic options other than subsistence farming or performing back-breaking labor for low wages on the local sisal plantations. By choosing locally engaged tourism and learning about the challenges residents face, travelers can contribute to conservation while gaining a deeper understanding of the complex balance between protecting nature and supporting livelihoods.

The spiny forest around Ifotaka and Mandrare River Camp lies in a remote corner of southern Madagascar, typically reached by flying from Antananarivo to Fort Dauphin (Taolagnaro) and continuing by road for approximately three hours. A charter flight directly to the local airstrip can make the journey easier.

The best time to visit is generally May through November, when conditions are drier and wildlife walks are more comfortable. October is baby lemur season, so keep that in mind if you love baby animals as much as we do.

For a deeper immersion in the cultures and wildlife of southern Madagascar, consider combining the spiny forest with a few restorative days at Manafiafy Beach & Rainforest Lodge, where coastal forest walks, vibrant birdlife, and the fishing villages on the Indian Ocean offer a very different experience.
