Skyrail

Skyrail is one tourist attraction that actually lives up to its hype. Constructed by heliocopter with painstaking care to avoid damage to the rainforest, it's a 4.5 mile gondola ride down the mountains, with stops along the way where you can walk around in the forest & view dramatic gorges & waterfalls. A fabulous ride & so quiet you can clearly hear the birds & animals in the forest below you.

As you can see by the picture, it's very inobtrusive. You have to look carefully to see the towers & gondolas.
