We took a short day sail to the popular sailing destination, Devil’s Island, from Kourou, French Guiana. It took us 2.5 hours to sail the 9.9 nautical miles. When we arrived, it felt like paradise!

Our sailing friend had caught a huge Spanish Mackerel, so we grabbed a bottle of wine and some cheese and joined him onshore for a fish fry with fantastic fresh fish and even more fantastic company.

The next day we hoisted the hook and took a short motor sail (about 30 minutes) to Bora Bora Cove at Ile de Diable (Devil’s Island), which is the Alcatraz of the Atlantic.

The prison system stretched over several locations, on the mainland and in the The penal colony of Cayenne, commonly known as Devil's Island (Île du Diable), was a French penal colony that operated in the 19th and 20th centuries in the Salvation's Islands of French Guiana. Opened in 1852, the Devil's Island system received convicts deported from all parts of the Second French Empire. It was infamous for its harsh treatment of detainees, with a death rate of 75% at their worst, until it was closed down in 1953. 

Devil's Island was notorious for being used for the internal exile of French political prisoners, with the most famous being Captain Alfred Dreyfus.

Île du Royale (the largest of the Triangle Islands—where we anchored the first time) was the reception center for the general population of the penal colony. They were housed in moderate freedom due to the difficulty of escape from the island. 

Saint-Joseph Island was the Reclusion, where inmates were sent to be punished by solitary confinement in silence and darkness for escapes or for offenses committed in the penal colony. 

As horrific as the island was in year’s past, let me assure you that with plush coconut palms, rich vegetation, clear waters in every shade of green and blue, natural swimming coves, and curious wildlife, this place is paradise!

Once settled at our anchorage in Bora Bora Cove, we took our two beagles to shore on Devil’s Island to explore. A tiny island, the dogs ran and played and explored. At the top there were dilapidated stone buildings that looked like forts and must have been quarters for the prisoners. There was not another human on the island while we were there, and later we learned that it is not legal to go on the island. Oops!

The views were spectacular but getting in and out of the dinghy was a challenge with waves crashing onto the shoreline rocks.

We spent the next couple days exploring all of Ile du Salut and went swimming in the natural shoreline pool. The dogs were captivated by the monkeys, red rump rodents, birds, and other wildlife on the island.
