Molokai Sea Cliffs | Molokai

The Molokai Sea Cliffs are a series of exceptionally tall marine cliffs located on the northern coast of Molokai, Hawaii, USA.

These geological formations represent the highest sea cliffs in the world.

Visual Characteristics

The cliffs are composed primarily of basalt rock, exhibiting dark grey and black coloration. They rise vertically from the Pacific Ocean, with sheer drops often exceeding 1,000 meters (3,300 feet). Vegetation is sparse on the exposed rock faces, with hardy grasses and shrubs clinging to ledges. Water at the base of the cliffs is deep blue, transitioning to a lighter turquoise closer to shorelines where sediment may be present.

Location & Access Logistics

Access to the Molokai Sea Cliffs is primarily by boat or helicopter due to their remote and inaccessible nature by land. No public roads lead directly to the cliff bases. Boat tours depart from Kaunakakai Harbor, approximately 30 kilometers (18.6 miles) southwest of the main cliff sections. Helicopter tours operate from Molokai Airport (MKK).

Historical & Ecological Origin

The Molokai Sea Cliffs are the result of massive ancient landslides that occurred millions of years ago, exposing the island's volcanic core. They are geologically classified as coastal cliffs formed by erosion and mass wasting.

Key Highlights & Activities

Boat tours offer views of the cliff faces and sea caves. Helicopter tours provide aerial perspectives of the scale and topography. Observing seabird colonies that inhabit the cliff faces is a common activity. Limited, strenuous hiking opportunities exist on the plateau above the cliffs, with designated trails offering distant views.

Infrastructure & Amenities

There are no facilities directly at the sea cliffs. Restrooms and food vendors are available in Kaunakakai town. Cell phone signal is generally absent along the cliff faces and surrounding waters.

Best Time to Visit

The best time for boat tours is during the calmer summer months (June to September) when ocean conditions are most favorable. Mid-morning offers good lighting for photography from the sea. Helicopter tours are generally less affected by sea conditions but are subject to weather patterns.

Facts & Legends

Local legend states that the cliffs were formed by the demigod Maui, who pulled the island of Molokai from the sea. A verified geological fact is that the cliffs are still actively eroding, with smaller rockfalls occurring periodically.
