A Geological Trek Across the Dragon


A glass bottom boat takes you over a vibrant coral reef teeming with fish on the way to the geological wonderland of the Minokoshi Coast.

Here, an entertaining guided coastal hike will take you tens of thousands of years back in time. See all manner of strange (and very photographable) features and learn about their, sometimes surprising, origins. Marvel at sudden crevices that glow with bright blue water, sit in mermaid caves and ponder the processes that created formations more akin to art than nature.

This tour ends with a lush forest walk and a beautiful 360-degree hilltop view of the surrounding National Park.
