Abstract. We study the Weil-Petersson (WP) geodesics with narrow end invariant and develop techniques to control length-functions and twist parameters along them and prescribe their itinerary in the moduli space of Riemann surfaces. This class of geodesics is rich enough to provide for examples of closed WP geodesics in the thin part of moduli space, as well as divergent WP geodesic rays with minimal filling ending lamination. As an intermediate step we prove that hierarchy resolution paths between narrow pairs of partial markings or laminations are stable in the pants graph of the surface
