Malpelo Island

Malpelo Island is a small, uninhabited Colombian island in the eastern Pacific Ocean, offshore of mainland Colombia, known for its rugged volcanic rock and surrounding deep-sea habitats. The island and adjacent waters form a nationally protected Fauna and Flora Sanctuary and a UNESCO World Heritage Site.

The marine environment features steep underwater walls and seamounts that attract large schools of hammerhead sharks and other pelagic species, making it a premier but remote dive destination. Terrestrial visits are rare; the island itself supports seabird colonies and very limited vegetation.

The site was declared a protected sanctuary by Colombia and inscribed as a UNESCO World Heritage Site in recognition of its outstanding marine biodiversity. Management focuses on strict conservation and regulated dive access.

Malpelo sits roughly in the eastern Pacific several hundred kilometres off Colombia’s Pacific coast; the nearest major ports on the mainland are several hours by boat or overnight by specialised vessel used by dive operators.

• Protected status: Designated a UNESCO World Heritage Site and Colombian Fauna and Flora Sanctuary, the area is internationally important for shark aggregations and pelagic biodiversity.
• Diving and access: World-class diving offers sightings of schooling hammerhead sharks, silky sharks and large pelagics; access is remote and typically arranged through licensed dive operators with permits.

What to See #

• Island rock: The rocky island itself is a steep, uninhabited outcrop rising sharply from deep water; terrestrial habitat on the island is limited and supports seabird colonies.
• Marine reserve: The surrounding marine sanctuary extends into deep ocean waters with steep walls and seamounts that attract large pelagic species; the protected zone is managed by Colombia's environmental authorities and restricts access for conservation.
