Muliwai a Pele, meaning River of Lava, is a notable spot along Chain of Craters Road. It provides a view of the Maunaulu lava flows that crossed the road from 1969 to 1974. The lava channel near the overlook, active for only three days, created various channels, lava formations like accretionary lava balls, and levees.

On the uphill side of the road is the Maunaulu lava shield, shaping the extensive lava field. The glaze on the pāhoehoe flows, reflecting from the silica-laden surface glass, adds a touch to the landscape. Vegetation here faces challenges from harsh winds and tough lava, resulting in sparse greenery.

In this rugged terrain, federally protected nēnē, the emblematic goose of Hawaiʻi, find refuge. Their presence showcases successful conservation efforts that saved them from near extinction. Once abundant throughout Hawai'i, hunting and predators nearly wiped them out. By 1952, only 30 nēnē remained. Through conservation, these geese were reintroduced in the 1960s, and by 2010, their population had grown to over 2,000 birds statewide. As you explore, slow down for these remarkable birds, respecting the delicate balance of nature that perseveres against all odds
