Soar through the treetops high above the jungle canopy, immersing yourself in Fiji's tropical landscape on a thrilling zipline ride. Under the supervision of trained guides, whiz down 16 different lines and take in spectacular views of the forest below and the island scenery beyond.

Feel the white-knuckled rush as you zip down the lines at 1 of 2 different island courses—one just 35 minutes outside of Nadi and the other just inland from Fiji's outdoor adventure capital, Pacific Harbour. On both courses, expert guides get you situated in your harness, provide tips for getting the most out of your experience, and point out natural features that you don't want to miss.

Nadi Course The exhilarating Nadi course features 16 different lines between 27 platforms, covering a total of 3 miles (5 km) and granting you views of the ocean, old growth vesi trees, and raintrees in the lower sections of the mountain. As you leap from one platform to the next, look out into the distance to spot the Mamanuca Islands, Plantation Island, and the blue waters of Tavarua, a popular surfing spot. You can also enjoy the added adventure of exploring some of the island's fascinating limestone caves as you walk into the stalactite-decorated depths of the Tau Caves.

Pacific Harbour Course Located on a lush, private eco-reserve just 25 minutes from town, the Pacific Harbour course features 8 ziplines that circle the canopy twice for a total of 16 adrenaline-charged flights—covering almost 1.5 miles (2 km) in all. Admire breathtaking views from each platform, looking down on the winding ribbon of the Waianadoi River and the green slopes of the surrounding valley.
