Hualālai

Hualālai is a volcanic mountain on the western side of the Island of Hawaii, one of the five major volcanoes that form the island. It reaches about 2,521 metres in elevation and is the island’s westernmost major volcanic mass.

The volcano has a history of eruptions, with the most recent documented activity around 1800-1801, and is classified as active though much of the flank is presently quiet. Its slopes include lava flows, rift zones and cinder cones, with modern developments such as residential areas and resorts on the lower flanks.

Hualālai rises above Kona and the west coast resorts and is visible from much of the western island. Road access reaches lower elevations and hiking routes require preparation and local information for safety.

• Height and last eruption: Elevation is 2,521 metres (8,271 feet); the volcano last erupted around 1800-1801 and is considered an active but currently quiet volcano.
• Access and land use: Lower slopes are developed with resorts and residential areas; access to higher routes requires care and local guidance due to rough terrain and remoteness.

• Check access and respect private‑land and resort boundaries - much of Hualālai's lower slopes are occupied by resorts and ranches, so use public viewpoints and designated pullouts along Mamalahoa Highway for safe, legal views.
• If you want to approach hiking routes, confirm current trail access and conditions with Hawai'i County or local visitor centers first; trailheads and permissibility can change and some routes require permits or are routed through private property.
• Plan visits to coastal viewpoints around sunrise or late afternoon for cooler conditions and the best light on the mountain silhouette; these times are also less busy at lookout pullouts.
