In general, of course, you don't know the destination vertex (else you would not need to solve the problem).

Interior point methods (http://en.wikipedia.org/wiki/Interior_point_method) "go through" the feasible region, but there is non-trivial work to be done recovering a vertex solution at the other end. They're faster for some LPs but not for all.
