Next travel to the crown jewel of the Big Island, Hawaii Volcanoes National Park. Briefly visit the Kilauea Iki Overlook before heading off on foot down the paved road to Keanakakoi. Check out the activity here from the historic 2018 eruption which buckled the road and caused racks and sinkholes. You’ll get a birds-eye view of the Kilauea Caldera and the enormous Halema’uma’u Crater, along with views of the trail you will take into the Caldera. This trail has been used to hike into the caldera since being established in 1846. Mark Twain was once rescued by native guide Alex Lancaster using this trail. It’s about 2 miles roundtrip taking you past the famous Sulphur Banks, through ancient forests of tree ferns, some as old as 1,000 years. Look for native birds, such as the yellow ‘amakihi and the red ‘apapane. Huge boulders came to rest here during ancient rock slides and eruptions. Look for marks left by previous visitors such as Benjamin Boyd, a Scot, and John Webster, a California artist, from back in 1851. Reaching the floor of Kilauea Calder there is an incredible rock slide to your left, evidence of the 2018 eruption, and Halema’uma’u Crater before you. The Crater increased in size during the eruption with the lava lake draining out of it leaving behind an enormous 1,000 foot deep pit. Return to civilization at Volcano House for some beautiful views.
