Summary

Channel Islands National Park protects islands off California in the United States. Isolation has shaped distinctive wildlife and plant communities, while cliffs, coves and marine habitats connect the islands with the Pacific.

Their appeal is the sense of a separate ecological world close to the mainland. Island forms and living habitats reveal how relatively short distances can produce substantial differences in nature.

Choose a base

Ventura or Oxnard

Getting there

Take an Island Packers boat from Ventura or Channel Islands Harbor, choosing the departure for your particular island. There is no island road transport for visitors.

Plan ahead

Reserve the boat in advance; island camping needs a separate reservation. Match the campsite to the boat schedule and bring the food and water your island requires.

For the curious reader

History, landscape and context.

Channel Islands National Park is a national park of the United States, which consists of five of the eight Channel Islands off the coast of California. Although the islands are close to the shore of the densely populated state, they have been relatively undeveloped. The park covers 249,561 acres (1,9.94 km²; 389.939 square miles), of which 79,019 acres (319.78 km²; 123.467 square miles) are federal land. Lower Tertiary sequence of rocks are found within the Christi Anticline on the southwestern part of Santa Cruz Island. The sequence includes the Pozo Formation, Canada Formation, Jolla Vieja Formation, and the Cozy Dell Formation.
