About eight kilometres off the west coast of Praslin, the second most populated island in the Seychelles, Cousine offers small group tours.
The new excursion experience on the remote island, which is also home to a small boutique hotel, is open to both locals and tourists.
The Guest Observer on Cousine Island, Ms Michelle Pretorius, explained that visitors will be greeted by the conservation team upon arrival and that they will be briefed on the island's conservation programme.
Visitors will then meet the various species that call Cousin home on a guided tour of the island's plateau, while all precautions are taken to minimise disturbance to the wildlife.
"To minimise disturbance to wildlife and guests on the island, we can accommodate a maximum of six visitors per day," Ms Pretorius said.
The visit takes about 5 hours, including a three-course lunch for visitors to relax and enjoy the scenery, including the clear, azure waters around the island.
"As we are a conservation island with a strict invasive species protocol, we only allow our boat to access the island. We can collect visitors from Praslin or book a helicopter transfer at an extra cost," said Ms Pretorius.
