Cape vs. Island: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on November 6, 2023
A cape is a pointed piece of land that sticks out into a sea, ocean, lake, or river; an island is a piece of land surrounded by water.

Key Differences

A cape is a high point of land that extends into a river, lake, or ocean, typically less substantial in land mass than an island. An island, by contrast, is a body of land completely surrounded by water and can support a wide range of habitats and ecosystems.
While a cape is a specific geographical feature marked by its prominent extension into water, creating a distinct point or headland, an island is an isolated landform that can range from a small islet to a large landmass like Greenland.
Both capes and islands can be significant for navigation; capes serve as markers for coastal navigation, whereas islands might be waypoints or destinations in oceanic travel.
The formation of a cape is typically the result of differential erosion, with the harder rock remaining to jut into the water, while islands can be formed through volcanic activity, sediment build-up, or rising sea levels.
Despite their differences, both capes and islands are often characterized by their unique flora and fauna, shaped by the forces of isolation and exposure.

Cape and Island Definitions


A narrow piece of land projecting into the water.
The cape was outlined by cliffs that dropped sharply into the ocean.


A piece of land surrounded by water.
The island could be seen on the horizon, a small green oasis in the vast blue sea.


Often a marked point for maritime pilots.
The lighthouse on the cape has guided ships for over a century.


Can be a habitat for unique species.
On the island, scientists discovered species of birds not found anywhere else.


A point of land jutting into the sea or a lake.
Sailors used the high cape as a landmark to navigate the coastline.


A landform that can support human habitation.
The island has its own community, complete with a school and a small hospital.


The tip of a coastal landform.
We hiked to the end of the cape to watch the sunset over the water.


Often a location for resorts or retreats.
They planned a vacation to a tropical island for their anniversary.


A distinctive land feature that can affect local climate.
The winds around the cape can be treacherous due to its shape and position.


Can be formed by volcanic activity.
The island was actually the top of an underwater volcano.


A sleeveless outer garment fastened at the throat and worn hanging over the shoulders.


Abbr. Isl. or Is. or I. A landmass, especially one smaller than a continent, entirely surrounded by water.


A brightly colored cloth used in maneuvering the bull in a bullfight; a capote or muleta.


An unattached kitchen counter providing easy access from all sides.


A point or head of land projecting into a body of water.
