Day Trips from Cayenne

Three small islands 15 km offshore once served as a dumping ground for French convicts. Now agoutis and howler monkeys run the show instead of guards. Stroll the restored cell blocks on Île Royale, swim off the convict-built dock, then take a small boat around Île du Diable, the still-closed 'Devil's Island' made famous by Papillon. Morning catamarans give you four solid hours before the sail back.

A riverside Hmong village that feels more Laos than Latin America. Sunday is market day: stalls sag under fresh spring rolls, tart passion-fruit cordial, and hand-woven baskets. After eating, hike the 3-km path to Folle-River cascade or rent a pirogue to drift past riverbank mango farms. Most visitors pair it with the floating market at nearby Roura on the way back.

French Guiana's modern claim to fame is the European spaceport. Free twice-daily buses roll you past the Ariane, Vega and soon-to-fly Ariane 6 launchpads. Between tours, wander the seafront Creole restaurants and grab space-themed ice cream (vanilla with star-shaped sprinkles) at the marina. Time it right and you'll hear the weekly sonic boom of a Vega lift-off.

Start with a dawn stroll on the leatherback-turtle nesting beach at Montjoly (October, March), then push south on the laterite track to Kaw village. Swap to an aluminium pirogue for a two-hour glide through Kaw Swamp RAMSAR site, watch for scarlet ibis, black caiman and the occasional manatee snout. Back on land, lunch on local couac crab stew before the dusty ride home.

Head north-west to the mouth of the Sinnamary River where Creole fishermen still use bamboo traps. After grilled snapper on stilt-pier shacks, drive another 40 min to Awala-Yalimapo, one of the world's densest leatherback-turtle beaches. Guides with red flashlights lead you (quietly) to watch 400-kg females dig nests March, July. Between sightings you'll hear surf louder than any traffic Cayenne ever manages.

Short on time but want Atlantic surf and a slice of history? Cycle or Uber to the southern suburb of Remire-Montjoly and follow the coastal footpath past ruined 19th-century brick kilns to Fort Diamant, a tiny star-shaped battery that once protected Cayenne from Portuguese privateers. Continue to the Rorota Trail viewpoint for a canopy-level view over the city's red-tile roofs.
