Meet the giant tortoises of Prison Island

Prison Island has a very enigmatic name. It was originally privatised by the first Sultan of Zanzibar as a place of detention for unruly slaves. It was later transformed into a prison, but was never really used. Later, it became a quarantine centre for people suffering from yellow fever. It wasn't until 1919 that its role became more pleasant, as it ended up housing 4 giant Galapagos tortoises, given to Zanzibar by the governor of the Seychelles. But from then on, some traffickers began stealing them and selling them on. In response, the Zanzibar government set up a programme to protect its giant tortoises. To date, the small island has no fewer than 200 turtles. Some of these grand ladies are almost twice a hundred years old.

Prison Island is easily accessible from Stone Town. You'll inevitably be accosted as you stroll along the streets by fishermen or beach boys offering you an excursion. You have two options. The travel agency with the big boats, easy to find and at a fixed price. Or the small fisherman, with whom you negotiate. The advantage of the small fishing boat is that it gives you a more authentic and relaxing experience. The price of the excursion varies according to the option you choose and, above all, your negotiating skills. It takes around 20 minutes to get to Prison Island from Stone Town and half a day to make the most of the island and its surroundings. You can stay at the one and only hotel on the island. But you'll find more choice in the town of Stone Town.

When you visit the giant tortoise sanctuary (allow at least 30 minutes), you're sure to be surprised by their impressive shells. You will then learn about the protection programme set up by the government to safeguard these hundred-year-old giants. You'll then have plenty of time to wander around with them. You are allowed to touch, stroke and feed the turtles. But don't forget that these are fragile animals and that they can feel your touch beneath their large shells. So make sure you respect them and their environment. And above all, don't get on their backs!

Although the giant tortoises are the island's main attraction, make the most of your excursion to discover more of its hidden beauty. Don't forget your swimming costume, it's time to stroll along the beach and discover the ocean to swim in the majestic coral reef that borders the island. Generally, the guide you choose will be able to provide you with the equipment you need for snorkelling (remember to let him know before you set off). All you have to do is dive from the boat into the coral reef, which is a beautiful sight to behold. Snorkelling is easy and open to all. The depth is generally no more than 2 metres. The site is one of the most beautiful in the archipelago, so you'll have plenty to see.

After admiring the seabed in search of the most beautiful fish, you can enjoy a tour of the old prison and a drink in the bar. The island's historical past is interesting, but there is little information about it unless you opt for an on-site guide. Otherwise, you're free to explore the island as you please (don't worry, your boat will be waiting for you at the quayside). During your exploration of the island by land, you may be lucky enough to spot some magnificent peacocks or dik-diks, which are small antelopes (very cute).
