No, that's not always the case as there are several references within NFPA 13 
dealing with a concealed space that has limited access.   So the space may have 
access and still be a concealed space.  

Typically a concealed space is one that does not permit occupancy or storage, 
has limited or no access, and whose area is not readily viewable from the 
occupied space.

Is there anywhere in 13 where a concealed space is defined? I have some
