Trailhead
Santa Cruz Island, Channel Islands National Park, California
Prisoners Harbor Trailhead is a source-backed overnight access point in Channel Islands National Park. Kampilo publishes only the official trail geometry and permit or camp authorization options represented in the mapped catalog.
The mapped line is a planning reference rather than a guarantee of current access. Confirm road, parking, trail, weather, fire, permit, and closure conditions with the land manager before departure.
Seasonal access
No recurring date-based closure of Prisoners Harbor Trailhead is published. Boat access · reservations required and temporary emergency orders still control access.
Boat access · reservations required: Reserve both authorized boat transportation and Del Norte camping, confirm landing conditions, and carry all water and supplies from Prisoners Harbor. Channel Islands trips depend on authorized boat service, landing conditions, weather, ocean conditions, and island-specific closures. Santa Rosa beach quadrants can close for wildlife protection, storm damage, or fire recovery; there is no backcountry drinking water.
For Santa Rosa, confirm that the selected northwest or southwest beach quadrant is open on the fire-recovery page, then verify the permit, boat itinerary, landing, pickup, and weather. Carry all water from the mainland.
