Sahamalaza-Îles Radama National Park: Forest Peninsula & Remote Archipelago

a protected forest peninsula and remote coral archipelago, reached only by sea

Explore

The journey begins not with an arrival, but with a letting go. Aboard a private dhow, its sail catching the steady breath of the Mozambique Channel, the familiar world recedes. The journey here is measured not in kilometres but in the gradual shifting of the water’s colour, from coastal turquoise to the profound indigo of the open channel. The air, thick with salt and the distant scent of ylang-ylang from coastal plantations, softens as the first of the Radama Islands appears on the horizon.

This is the approach to Sahamalaza-Îles Radama National Park, a UNESCO Biosphere Reserve that holds two worlds in delicate balance. It is a fragment of ancient, humid deciduous forest clinging to a mainland peninsula, and an archipelago of four coral-fringed islands scattered like emeralds across a sapphire sea. The park protects one of the last significant stands of this coastal forest ecosystem, a final refuge for species found nowhere else.

This is the ancestral territory of the Sakalava people, whose lives remain intrinsically woven into the health of both the forest and the reef. Their maritime culture and stewardship are the quiet, human pulse of this wilderness; a relationship with the environment that has shaped the character of the land and sea over generations.

Access is exclusively by private sea vessel, a logistical reality that keeps this dual ecosystem entirely separate from the main travel circuits.

Landscape & Geography

The park is a composition in two movements: land and sea. On the Sahamalaza Peninsula, a rare remnant of northwestern coastal deciduous forest survives, its canopy alive with endemic wildlife. This terrestrial portion gives way to the Mozambique Channel, where the four main islands of the Radama archipelago—Nosy Antany Mora, Nosy Valiha, Nosy Berafia and Nosy Kalakajoro—are scattered. Designated a UNESCO Biosphere Reserve in 2001, the park protects 321,000 hectares of interconnected terrestrial and marine habitats, from forest floor to coral reef.

The Experience

A visit is defined by the rhythm of the sea. Days are spent sailing between islands, anchoring in deserted bays and coming ashore to explore. On the peninsula, guided forest walks focus on finding the park's lemurs. In the archipelago, the focus shifts to the water: snorkelling over vibrant reefs, kayaking through mangrove forests that act as vital marine nurseries, and enjoying picnics on sandbars that appear only at low tide. The experience is not about covering distance, but about immersion in a place where the line between land and water is constantly blurred and the only schedule is the tide.
When to Go & Access
The park is best visited during the dry season, from May to October, when seas are calm, skies are clear and underwater visibility is at its peak. Access is the defining characteristic of a Sahamalaza journey. There are no roads into the park. Entry is exclusively by sea, typically via a private, multi-day charter on a catamaran or dhow departing from Nosy Be. This requires significant forward planning and coordination, as the vessel serves as your base for transport, accommodation and exploration for the entire duration of the trip.

Conservation & Community

Sahamalaza-Îles Radama is a critical conservation frontier. The forest shelters the last viable populations of the Blue-Eyed Black Lemur and the Sahamalaza sportive lemur, both critically endangered. The reefs are a vital genetic bank for the wider Mozambique Channel. By working with the local Sakalava communities, Madagascar National Parks (MNP) aims to create a sustainable model where conservation-focused tourism provides an alternative to deforestation and destructive fishing. Your visit, conducted with the highest standards of ecological respect, directly funds the rangers and community projects that are essential for the park's defence.

Wildlife to Encounter

Blue-Eyed Black Lemur

One of the few primates besides humans with blue eyes; this critically endangered lemur is found only in the forests of the Sahamalaza Peninsula.

Sahamalaza Sportive Lemur

A nocturnal lemur known to science only since 2006; sightings require patient, expert-guided night walks in its small, protected territory.

Hawksbill Sea Turtle

Frequently encountered whilst snorkelling over the seagrass beds and coral reefs of the Radama Islands, often allowing for calm, close observation.

Green Sea Turtle

Another common resident of the park's marine ecosystems, spotted surfacing for air from the boat or grazing in shallow coastal waters.

Indo-Pacific Bottlenose Dolphin

Social pods are a regular sight in the channel between the islands, often seen riding the bow wave of the boat.

Acropora Coral

These branching, table-like corals form the backbone of the archipelago's healthy reefs, creating a complex habitat for hundreds of fish species.

Frequently Asked Questions

How do I get to Sahamalaza-Îles Radama? ›

Access is exclusively by sea on a multi-day private charter, usually a catamaran or traditional dhow. Expeditions typically depart from the island of Nosy Be, which is reachable by domestic flights.

What is the accommodation like? ›

Accommodation is on your private vessel. Catamarans offer comfortable cabins with en-suite facilities, providing a floating base for the entire journey. There are no hotels or lodges within the park boundaries suitable for this type of expedition.

How long should I allow for a visit? ›

We recommend a minimum of four days and three nights to experience both the terrestrial and marine environments properly. This allows for sufficient time for sailing, forest treks and snorkelling without feeling rushed.

What level of fitness is required? ›

A moderate level of fitness is suitable. Activities include walking on uneven forest trails, swimming, and getting on and off the vessel via a dinghy. The trekking is not exceptionally strenuous, but agility and a degree of comfort in the water are important.

Is this a good destination for snorkelling and diving? ›

It is an exceptional snorkelling destination due to the reefs' isolation and health. The experience is about pristine conditions and solitude. Whilst diving can be arranged, the quality and accessibility of the shallow reefs make snorkelling the premier activity.

What is the best time of year to go? ›

The dry season, from May to October, offers the most reliable weather. During these months, you can expect calm seas, abundant sunshine and excellent conditions for all marine and terrestrial activities.
