The Atlantic Frontier

Arrive in Banjul, the smallest capital on Africa's Atlantic coast, where the expedition vehicles are waiting. The evening opens with the convoy briefing — the route, the protocol, the seven countries ahead — and closes with sunset over the mouth of the Gambia River, where the line begins.

The convoy rolls south over the Gambian border and into Senegal's Casamance, a region of slow rivers and mangrove channels that feels like a country of its own. The day ends in Ziguinchor, the old river port on the Casamance River, its waterfront unhurried in the evening heat.

A shorter day west along the Casamance's back roads to the Atlantic at Cap Skirring, through fishing villages and sacred-forest country. The afternoon belongs to the coastline and its communities; the evening belongs to one of the finest sunsets in West Africa.

The first rugged border of the expedition takes the convoy into Guinea-Bissau, one of the least-visited countries on Earth. The day ends in Bissau, its faded Portuguese capital — grand colonial avenues, a crumbling presidential palace, and a slow, likeable rhythm all its own.

East through savannah and cashew country, the villages thinning and the horizons widening, into the market towns of the deep interior. Gabu — once the seat of its own kingdom — is the night's stop, and the staging post for the climb into Guinea.

A remote crossing lifts the convoy into Guinea and up onto the Fouta Djalon, the green highland heart of the country. The air cools with the altitude on the climb to Labé, the plateau's Fula capital and the base for the highland days.

A long highland day south through the Fouta Djalon's waterfalls and forested valleys, with the stops dictated as much by the road as by the plan. The plateau gives way stage by stage toward Kindia, the convoy's last night before the coast.

The expedition's hardest border day: the crossing into Sierra Leone can take an hour or an afternoon, and the convoy is built for either. On the far side waits one of the great arrivals in Africa — Freetown, spread over its green hills above the Atlantic.

A full day in Freetown without the vehicles: the markets, the colonial-era landmarks of the freed-slave settlement, the white-sand beaches down the peninsula, and time with the community projects we support here. Few capitals reward a day on foot the way this one does.

The defining overland segment of the expedition — a long day through remote south-eastern Sierra Leone to the Liberian border, one of the most complex crossings on the route. Terrain, not distance, sets the pace, and Monrovia's lights at the end of it feel earned.

A day in Monrovia, the capital founded by freed American slaves and still carrying America in its street names, its flag, and its accents. We explore its coastal districts and its layered history with people who lived that history's most recent chapters.

The one flight of the expedition lifts over the roadless gap between Monrovia and Abidjan, where the Ivorian vehicles are waiting. The drive north ends at Yamoussoukro for the reason everyone comes: the Basilica of Our Lady of Peace at sunset — one of the largest churches on Earth, alone against the bush.

In the Guro villages beyond Yamoussoukro, the Zaouli mask dances — feet moving faster than the eye can follow beneath a serene carved face, one of West Africa's most striking living traditions. Then south to Abidjan, the lagoon city, for the expedition's closing dinner.

Fourteen days, seven countries, one road behind us. Breakfast, a last look over the lagoon, and transfers to Abidjan's airport for onward flights — the line from the Gambia River to the Ebrié Lagoon complete.
