Gardner Pinnacles

Islands Tiny volcanic islets in the Northwestern Hawaiian Islands

In the Northwestern Hawaiian Islands, Gardner Pinnacles are remote limestone outcrops within Papahānaumokuākea, accessible only by research or conservation permit. Scientists and seabird watchers note nesting colonies, offshore marine life and uninhabited reefs.

The Gardner Pinnacles are two small, rocky islets rising from a submerged volcanic mountain in the Northwestern Hawaiian Islands. They form a tiny, barren outcrop surrounded by reefs and deep ocean waters.

The islets are uninhabited and notable mainly as navigation markers, seabird habitat and components of the remote Hawaiian island chain. There are no facilities and landings are rare and generally restricted.

They are administered as part of the State of Hawaii and are included within the broader protected area of the Papahānaumokuākea Marine National Monument, which manages conservation of the archipelago’s marine and avian ecosystems.

The pinnacles lie in the central Pacific Ocean well northwest of the main Hawaiian Islands, forming part of the long, narrow chain of islands and reefs that extend across the central Pacific.

Conservation status: Part of the Northwestern Hawaiian Islands and included in the Papahānaumokuākea Marine National Monument, subject to conservation protections.

Tips for Visiting Gardner Pinnacles #

The Gardner Pinnacles are uninhabited and remote-access requires a private vessel and permission from Hawaiian authorities.
They are a bird and marine life refuge; avoid landing except with explicit authorization and follow state rules about protected areas.
Bring sea-sickness medication; the pinnacles sit in open ocean and boat rides can be long and rough.
