Prison Island was lovely. - I really loved the entire island. The tortoises were interesting but the museum outlined the history in an interesting and fascinating way. The shop was one of the best I've seen with a large variety of items. The pace was leisurely. We never felt hurried even though the island got a little crowded as the day went by. I would recommend arriving as early as possible to avoid the crowds.

Wonderful. - TOUR to Prison Island together with Nakupenda, a prison that has never really been used as such but as a quarantine place and where giant turtles were important from the Seychelles...many is giant. Then you go to Nakupenda which in local language means "I love you", here I have no words to describe the beauty the colors that there are .. a tongue of sand that appears and then disappears after a few hours, where you prepare the fish cooked at the moment .. delicious fresh fruit, crystal clear sea ... the best experience for me ..

Good, but be prepared - Turtle Island was fascinating. The boat ride out was also an adventure. Our guide was very friendly and excellent. However, Viator Should have notified people that they must Be prepared to walk out in a foot of water to the boat, therefore shorts or raised pants legs are mandatory.. Also, the boat trip out to the island had very rough water which guests should be prepared for.

Prison island again - Thou I have visited Prison island a few times already, it’s always nice to see it through another’s eyes. The trip through small boats is safe, we travelled with young children under 10 years. What I noticed was the water current is higher toward the end of the day, so perhaps not the very ideal time to travel! The peacock addition makes the place even more interesting!

Island out of time - Coupled with the spices and the Stone Town visit, the tour was very informative, especially as we were with a French guide! Out of time place that has been successful, with structures that are actually aging but that have been recycled in restaurants open in high season (which is not the case in April/May). The turtles are impressive and if you are an observer, you may be lucky enough to see one or two small "antelopes". Go around the whole island to take beautiful pictures and why not swim if your organizers give you time!

great to see, BUT - Overpriced — this is a tiny island with not much to see. Our guide didn't even flag the museum. It was definitely underwhelming.
