Hawaii's Big Island is still being built, and here you can stand on the evidence. Mauna Loa rises to about four thousand two hundred metres above sea level and is the largest active volcano on Earth by volume, while Kilauea beside it has been one of the most active, with eruptions that have repeatedly reshaped the south-east coast. The two together form the heart of Hawaii Volcanoes National Park, which is a World Heritage site. Mauna Loa itself woke in 2022 after thirty-eight years of quiet, a reminder that the mountain is not a museum piece.
The riding is more varied than people expect. From the south-west side, the Hawaii Belt Road, or Highway 11, climbs from the ocean through macadamia and coffee country into cool upland forest. Around the park, Crater Rim Drive circles the summit caldera of Kilauea and Chain of Craters Road drops almost nineteen miles down to the sea through old lava flows, with long open bends and a view of black rock meeting white surf. In the highlands it can be misty and wet, and temperatures drop sharply, so bring a rain layer. The air near vents can carry volcanic gas, known locally as vog, which is a problem for people with breathing issues, and some roads and trails close when conditions turn dangerous. Check the park's current status before heading out.
Hawaiian tradition honours Pele, the goddess of volcanoes, who is believed to live in Halemaʻumaʻu, the crater at Kilauea's summit. Rangers and local people will tell you that it is respectful not to take lava rocks away, and there are plenty of stories about luckless tourists who mailed them back. The landscape is unforgettable: steam rising from the ground, fields of ropey pahoehoe lava, ferns pushing up through cinder, and the endangered nene, Hawaii's state bird, wandering near the roadside.
Fuel is the thing to plan. Pāhala and Volcano village have small supplies, but the larger towns are Hilo to the north-east and Kailua-Kona on the other coast, both a long drive away. Fill up wherever you pass a station, bring water and food into the park, and plan for rain and cool temperatures even if the lowlands are hot.
