If you can get here by any means then I commend you for being able to travel to the most inaccesible areas in the Caribbean.
The islands is surrounded by a majority of reef and blue crystal water. It is entirely a national park with no form of settlement.
We saw another boat anchored here and we did not welcome close proximity or communication. The island is very close to Hati and drug trafficing is not unknown in the area.
Getting an organised tour from Great Inagua on a power boat would be a option? (maybe??)
