Camp Pendleton is about 125,000 acres in size, or roughly 195 square miles. That makes it one of the largest Marine Corps bases in the United States.

Quick scoop

  • The base covers a huge stretch of Southern California coastline.
  • One source describes it as 125,547 acres and notes it includes about 17.1 miles of Pacific shoreline.
  • Another recent article confirms Camp Pendleton is still in the news this week because of a brush fire on the base.

Simple comparison

To picture it another way, Camp Pendleton is bigger than many cities and large enough to include beaches, training areas, and rugged inland terrain all in one installation. That mix is part of why it is so important for Marine amphibious training.

TL;DR

Camp Pendleton is about 125,000 acres — roughly 195 square miles — making it a very large military base.
