Mauna Iki Trail to Pu'u Loa Petroglyphs

Embarking on the Mauna Iki Trail to Pu'u Loa Petroglyphs, hikers will traverse a diverse volcanic landscape that spans approximately 60 kilometers (about 37 miles) with an elevation gain of around 400 meters (roughly 1,300 feet). This point-to-point trail is nestled within the expansive Hawaiʻi Volcanoes National Park, near Hawaiʻi County, and is rated as medium difficulty, offering a challenging yet rewarding experience for those with some hiking experience.Getting to the Trailhead To reach the trailhead, visitors can drive to the Kīlauea Visitor Center, which is the nearest significant landmark. From there, follow the signs to the Mauna Iki Trailhead, located off Hilina Pali Road. Public transportation options are limited within the park, so driving is the most feasible way to access the start of the hike.Navigating the Trail The journey begins on a well-marked path that meanders through a stark yet beautiful volcanic landscape, characterized by vast lava fields and the occasional kīpuka—oases of vegetation that have been spared from lava flows. Hikers should be prepared for the heat and intense sun exposure, as shade is scarce on the lava plains. It's essential to carry plenty of water, sun protection, and sturdy hiking boots to navigate the rough terrain.As you progress, the trail will lead you through areas of historical significance. The Pu'u Loa Petroglyphs, which you'll encounter towards the end of the hike, are a sacred site to the native Hawaiian people. These ancient carvings etched into the lava rock are believed to date back over 500 years and are among the most extensive petroglyph fields in Hawaii.Flora and Fauna Despite the harsh volcanic environment, the trail is home to a variety of native Hawaiian plant and animal species. Keep an eye out for the hardy ʻōhiʻa lehua tree, which often is one of the first plants to colonize new lava flows, and its vibrant red blossoms. The trail also provides opportunities to spot local birdlife, including the Hawaiian hawk (ʻio) and the nēnē, Hawaii's state bird and a species of goose adapted to life on the islands.Safety and Preparation Due to the remote and rugged nature of the trail, it's crucial to be well-prepared. Hikers should inform someone of their plans and expected return time. It's also advisable to check in with the Kīlauea Visitor Center for the latest trail conditions and any volcanic activity updates.
