Diéku

Diéku is a 276-meter summit in the southern part of New Caledonia with wide views across the Pacific island landscape. Hiking trails take you through varying vegetation and reveal different perspectives of the surrounding region.

The mountain is part of New Caledonia's geological story, which traces back to when the ancient continent Zealandia formed. This geological connection appears in the rock formations and landscape structure you see along the way.

The mountain holds meaning for the Kanak people, who have maintained connections to this land through many generations. Walking through the area, you notice how the landscape reflects these long-standing relationships with the territory.

Well-established hiking trails lead to the summit and are easiest to navigate during the dry season from June to August. It is wise to check local conditions beforehand and bring appropriate gear for your climb.

The summit offers researchers chances to study unusual plant species that have evolved in the isolation of this Pacific island. These rare plants are not found anywhere else and make the location interesting for botanists.
