Meet your waiting driver in the morning when your cruise ship docks at the Limon port, and travel by minivan to a launch point on the Tortuguero Canal. Nicknamed ‘the Amazon of Costa Rica,’ this waterway winds though a protected biological reserve that’s home to a wildly diverse array of plant and animal life. Climb aboard a covered river boat, and cruise through the canal at a leisurely pace while a guide shares commentary on the rain forest ecosystem and helps you spot native creatures such as crocodiles, howler monkeys, sloths, iguanas, bats, and toucans. At the end of the canal cruise, take a short drive to the Jungle Breeze adventure park to begin your high-flying zipline tour. After a safety briefing from highly trained guides, gear up with provided equipment and climb to the first of 12 treetop platforms. From here, clip on to a series of 11 cables and let go to soar across the rain forest canopy at exhilarating speeds, taking in stellar views of the Caribbean along the way. After the fifth platform, the cables become increasingly longer, reaching a maximum length of 885 feet (270 meters) and heights of up to 263 feet (80 meters). If that's a bit beyond your comfort zone, there is an opportunity to finish the tour early and return to base camp at platforms 5 and 7. When you return to solid ground, transfer back to your waiting cruise ship in the afternoon.
