The islands are not often visited by cruising boats. They are a nature reserve with great snorkelling opportunities. Access to these islands is controlled and you must be accompanied by an official guide to get there. Here you can find 2 rare species:
the Kouwes snake (one of the rarest animals in the world) who lives on the Isla Maria Major.
The Zandoli Te, a species of land lizards.
In settled weather, you can day anchor on their lee side.
Enter from the south side of Maria Island being careful to leave the reef to starboard and the coral heads to port. Pass the southeast tip of St. Lucia and turn north, here you may encounter some tide rips which will flatten out as you continue north. In heavy weather, there are breaking seas and this area should be avoided.
