Sea Caves & Endemic Marine Life Coastal Walk

Walk the dramatic volcanic coastline of Cumberland Bay, exploring sea caves and observing the Juan Fernández fur seal colony that almost went extinct.

  1. 1

    Village Beach South End

    Head south along the rocky shoreline past colourful fishing boats pulled up on the black volcanic sand beach at the edge of the village.

  2. 2

    Fur Seal Rocks

    Juan Fernández fur seals bask on the coastal rocks — this species was hunted to near-extinction by sealers in the 18th century but has recovered remarkably.

  3. 3

    First Sea Cave

    A large sea cave carved by Pacific swells into the basalt cliff can be entered at low tide; its walls are covered in colourful encrusting organisms.

  4. 4

    Crystal Water Snorkel Spot

    The water clarity in these sheltered coves is exceptional — mask and snorkel reveal endemic fish species and underwater volcanic rock formations.

  5. 5

    Sea Arch Viewpoint

    A natural basalt arch carved by the sea frames a view of the open Pacific — a dramatic spot where waves surge through with tremendous force.

  6. 6

    Lobster Nursery Cove

    A sheltered cove where juvenile Juan Fernández lobsters hide in rock crevices, protected by the island's strict seasonal fishing regulations.
