Detailed itinerary

Stop 1

Start your adventure in quaint Hilo town where you’ll drive along the historic waterfront before arriving at Rainbow Falls. This iconic waterfall right off a postcard features an 80 foot tall twin waterfall system. Look for the rainbow effect that gives the waterfall its name!

Stop 2

Continue traveling up the Wailuku River to Boiling Pots. Impressive photo opportunities are often found here when the river “boils” through depressions in the rocks.

Stop 3

Explore Kaumana Caves, part of the lava tube system that brought lava 1.5 miles from Hilo-town in 1881. Take a peek inside the cathedral-like space before tucking into a quick picnic-style lunch atop the caves.

Your guide will take you to one of our preferred locations on Mauna Kea for nighttime stargazing. You’ll observe deep sky and planetary objects through a large aperture Dobsonian telescope under one of the darkest and most pristine skies on planet Earth! Our Dobsonian telescopes are a true purist’s experience to view the night sky. Their fast focal ratio enables you to see sprawling wide field views of objects that simply aren’t possible with the types of telescopes used by other tours. Depending on what is visible in the current sky and weather permitting, you’ll observe galaxies, nebula, star clusters, planets, double star systems, the moon, and much more; all the highlights and showpiece objects like you’ve never seen before!

Stop 5

Next, you’ll travel across Saddle Road between Mauna Kea and Mauna Loa, two of the tallest and most massive volcanoes on Earth. Your National Park Service trained guide will discuss the volcanology, geology, and history of these monstrous wonders, as well as providing in-depth narration on the various lava flows and flora and fauna that you’ll be passing by. While you’re taking in the breathtaking terrestrial views, your guide will prepare some heavenly views just as stunning. Setting up a state of the art solar telescope for your viewing pleasure, your specially trained guide will let you safely watch the sun come alive in true color with vibrant solar flares, sunspots, prominences and any other current activity weather permitting.
