Exploring San Miguel Island
Welcome to San Miguel Island, one of five islands in Channel Islands National Park. This is your island. It is also your
responsibility. Please take a moment to read this bulletin and learn what you can do to take care of San Miguel. This
information and the map on the back will show you what you can see and do here on San Miguel.
About the Island
San Miguel is the home of pristine tidepools, rare
plants, and the strange caliche forest. Four species
of seals and sea lions come here to breed and give
birth. For 10,000 years the island was home to the
seagoing Chumash people. Juan Rodriguez Cabrillo
set foot here in 1542 as the first European to explore
the California coast. For 100 years the island was
a sheep ranch and after that it was used by the
military. San Miguel is still owned by the Navy, but
it is managed under agreement by the National Park
Service. In 1980 it was designated part of Channel
Islands National Park.
Access Permit Required
A permit (inlcuding liability waiver) is required to
visit and hike on the island. They may be obtained at
concessioner offices and on the island.
On your own you may explore the Cuyler Harbor
beach, Cabrillo monument, and the Lester ranch
site.
Many parts of San Miguel are closed to protect
wildlife, fragile plants, and geological features.
Several areas, however, are open for you to explore
on your own. Others are open to you when
accompanied by a park ranger.
The Nidever Canyon trail will take you to the ranch
site, monument and ranger station. The trail begins
at the top of the dune above Gull Rock. It climbs
along the east wall of the canyon.
Contacting a Ranger
To see other parts of the island, such as Point
Bennett or the caliche forest, you must go with
a ranger.
The San Miguel ranger can be contacted on Marine
Radio Channel 16. You can also arrange a hike with
the ranger through park headquarters at (805) 6585730.
Island Rules
Everything is protected. Do not collect anything.
Take your trash off the island with you.
San Miguel Island is open only when National Park
Service personnel are on the island.
Hikers must stay on trails.
Access permit (including liability waiver) is required.

Safety
The island was a former bombing range and there

any munitions that you may find on or off shore.
It is extremely dangerous and may detonate at any
time. Report its location to a ranger, who will have
it removed by qualified personnel.
Hikers must be escorted except where indicated on
this map.
California State fishing regulations apply. No fishing
in marine reserves.
Hantavirus has been found in deer mouse
populations on San Miguel. This is a potentially
fatal disease and some basic precautions should
be taken: avoid contact with rodents; do not feed
wild animals; keep food and drink in rodent-proof
containers. For more information, please see the
bulletin board in the campground.
Use caution when crossing the rockfall along the
beach.
Carry plenty of water and drink it.
The Nidever Canyon trail is steep and slippery.
Watch your step.
