Swap the city streets for tropical waterways on this fun-filled speedboat and snorkelling adventure. After a quick briefing, you'll hop into your two-person boat and weave through the mangrove-lined channels of the Nichupté Lagoon, taking in the scenery as you cruise towards the coast. Then, it's time to dive in and snorkel above part of the world's second-largest barrier reef, spotting colourful marine life beneath the surface before heading back to the marina.
