In the class template Triangulation_3, which is the base of all 3D 
triangulations in CGAL, you have the iterator type 
"Finite_vertices_iterator", 
and the methods "finite_vertices_begin()" and "finite_vertices_end()".

If you want to iterate over all vertices, including the infinite vertex, 
there 
are "All_vertices_iterator" and the corresponding iterator methods.

In the 2D triangulations you can find similar iterator types and methods.
