Just a Stone's Throw Away

Use a Ferrystone while a Portcrystal exists to warp to. Two Portcrystals sit permanently in the world (Vernworth and Harve Village), so once you have a Ferrystone - you're given a few, or buy one - just open the map and warp to one. Ferrystones are single-use and pricey, but this pops on your very first use.
