During a recent visit to the 'Big Island' of Hawaii we traversed the islands Saddle Road between Waikoloa and Hilo, and gained dramatic views of extinct Mauna Kea and active Mauna Loa.
We also drove up to the Kilauea Caldera in the Vocanoes National Park and hiked part of the way around the perimeter. Steam and fumes were rising from the Halema'uma'u Crater within the caldera.
Later we travelled the Chain of Craters Road which led past several vents, across lava fields, down an escarpment and ended at the lava cliffs where the flow ended in the sea.
