Halema‘uma‘u and Keanakāko‘i Craters

The hiking experience here often combines two distinct paths. The Keanakāko‘i Crater trail is generally easy, following a mostly flat, paved section of the old Crater Rim Drive. The Halema‘uma‘u Trail is rated as moderate, involving a descent of about 425 feet (130m) into the Kaluapele (Kīlauea caldera) floor through a rainforest.

The full route, which is about 3.2 km (2 miles) long, typically takes around 50-60 minutes to complete. This duration can vary depending on how much time you spend enjoying the views at the Keanakākoʻi Crater Overlook and the Halemaʻumaʻu Crater Overlook.

You'll experience dramatic volcanic scenery, transitioning from ʻōhiʻa and koa forest to barren caldera landscapes. Key viewpoints include the Keanakākoʻi Crater Overlook, offering views of the 115-foot deep crater, and panoramic vistas of the much larger Halemaʻumaʻu Crater. You might also see smoking fumaroles and the Collapsed Road — Crater Rim Drive, showcasing the volcano's impact.
