Mnemba Island is a small island shaped like a triangle located in the Northern Tanzania. This small island is, however, full of activities for its visitors. It is a great site for diving, photography, a lazy vacation and swimming too. This small island is also known as Mnemba Atoll despite the fact that it is not actually an atoll. Mnemba is also famous for occasional visits from huge turtles and sights of happy dolphins. This island gives off very relaxing vibes overall and the weather is at its best in spring and autumn time.
