At the Vakona Forest Lodge, you can book tickets for a guided tour for 25,000 Ariari per person, which also includes a visit to the Vakona Crocodile Resort.
Here, you can experience the lemurs up close, and you might even find yourself with one sitting on your shoulders, as the guides are constantly trying to lure the animals with bananas.
The lemurs are bred here, and young ones are released into the wild after a certain period of time.
It's also possible to book a canoe tour around the islands.
A visit is definitely worth it.
