according to the documentation it seems to be the case :
"The polyhedral surface provides convenient circulators for the
counterclockwise circular sequence of halfedges around a facet and the
clockwise circular sequence of halfedges around a vertex."
( found on page
http://www.cgal.org/Manual/3.4/doc_html/cgal_manual/Polyhedron/Chapter_main.html
section 21.3.6 ).

If you don't trust it, you can still implement it by successions of
next()->opposite() operations, I guess.
