Is my tax sale property landlocked?

I purchased a parcel at a recent San Bernardino County, CA tax sale.
It was a great price (about 1/5 assessed value) so I took a chance.
Now, I need to find out if the parcel is land-locked or not.  How do I
go about discovering if I have some sort of easement (public perhaps?)
to surrounding property that grants me access.  Currently, there are
no roads that run to the property, but both the north and south
property lines would be where street run in surrounding sections of
land.  I just looks like they have not yet plowed a dirt road through
the particular set or parcels (it all dirt roads around here.  I'm one
or two parcels away from the west road, and three parcels from the
east road.  How do I find out if I have legal access?!  Thanks.
