Changuu Island (Prison Island)

Worth it if you're after a solid half-day snorkel-and-history combo with genuinely good feedback from nearly 1,700 people. The 4.6 rating suggests the tour operators know what they're doing, though paid entry plus transport costs mean it's a proper outing rather than a casual wander. Book early morning to dodge the cruise-ship crowds that pile in midday.
