Freeway Access
For
an American citizen the estuary and park’s main access is
from the large Interstate freeway which ends at the U.S. Port
of Entry at the Mexican border. To find this vast land of shadows
and green just take the Dairy Mart Road exit from the south bound
lanes of Interstate 5.

But
be careful. This is a hidden place and many do not want you to
find it. If you take the CALTRANS’ suggestion -- and make
your exit at Coronado Avenue -- you will not reach the park but
instead see only a cold gray concrete "tourist" or visitor’s
center many, many miles away.
Be
careful too, not to exit at the freeway's PRISON exit. There are
several prisons near the park and tourism is not encouraged.
Lastly,
and a great secret only you now know ... there is even a federal
facility deep within the park itself ready for the thousands of
miscreants who happen past its web of wire and searchlights.
While
the tension and excitement may be mounting please remember when
exiting the freeway to turn right at the first stop sign and then
actually stop at the second stop sign. There are police about.

The
entire area is like a hurricane — frenzied activity on the
exterior and near nothingness as you proceed deeper and deeper
into the secret parklands.
