Prison Island is famous for its sanctuary of giant Aldabra tortoises. While visitors get close to these massive animals, you must follow specific rules to keep them safe. Understanding these guidelines ensures your visit is respectful and enjoyable.

Are you allowed to touch the tortoises?

You can observe them closely, but you must avoid improper touching.

Sanctuary guidelines require visitors to keep a respectful distance. Do not poke them or touch their heads. If you offer them food, let them reach for it naturally. Staff monitor the Giant Tortoise Enclosure to enforce these safe interactions.

Can you ride the giant tortoises?

No. It is strictly forbidden to sit on, ride, or place heavy weight on the tortoises.

Although their shells look tough, bearing human weight causes severe internal injuries. Sanctuary staff will immediately intervene if anyone attempts to sit or climb on the animals. Keep your feet on the ground at all times.

What do the tortoises eat?

The tortoises eat specific leafy greens approved by the sanctuary.

You cannot feed the tortoises outside food. Bringing your own snacks harms their diet and health. Sanctuary staff provide the correct leafy greens inside the enclosure for you to use.

How do you feed the tortoises?

You buy approved leafy greens directly from the keepers to feed them.

When you enter the sanctuary, keepers offer small bunches of greens. Hold the stems out so the tortoise can bite the leaves. Watch your fingers, as their beaks are sharp.

How old are the tortoises you will see?

Some resident tortoises are estimated to be over 190 years old.

The original animals arrived in 1919 as a gift from the Seychelles governor. The oldest tortoise is known as 'Mzee' (Swahili for elder). You can identify the ages of younger tortoises by the numbers painted on their shells in the Baby Tortoise Nursery.

Do you need a guide for the sanctuary?

No, but a guide helps explain the rules and the island's history.

You can walk through the sanctuary on your own after paying the island entry fee (about $12 USD). However, many visitors book combo tours that include a local guide. A guide will point out 'Mzee' and ensure you follow the conservation guidelines.
