Mayumba

Gabon's coast hosts the world's most important leatherback nesting population, and Mayumba is one of its main beaches: a sand peninsula running dozens of kilometres between lagoon and open Atlantic, protected as a marine national park, where in season the giant turtles come ashore in large numbers, while humpback whales breach offshore in their winter months and the beach between arrivals belongs to ghost crabs and fishing eagles. The town is a sleepy fishing outpost; the park runs night patrols that visitors join under red-light rules, and the remoteness that keeps the beach dark for turtles keeps it honest for travellers.

The landscape

• The leatherback nights - nesting nights of earth's largest turtle.
• The empty peninsula - lagoon-to-ocean sand by the kilometre.
• Humpbacks offshore - the winter whale window from the beach.
• The lagoon side - calm-water pirogues and birdlife behind the dunes.

When to go

November to March is nesting's heart, moonless nights best; July to September swaps turtles for humpbacks offshore. Either window, arrange park guiding ahead - this is patrol-accompanied viewing only.

Practical notes

Getting there is the commitment: flights are sparse, the road long and seasonal, and facilities are basic guesthouses - the reward scales with the effort. Turtle rules are strict and enforced: red lights, distance, no flash, guides' word final. The Atlantic here is for looking; currents rule the swim question.
