This post office is right next to the grocery store. There is ample parking. You really can't miss it as there isn't really a lot in La Push but it's down a steep hill so drive slowly as I believe it's a native reservation. The post office is very small as La Push is very small so don't expect something large like a Seattle post office or somewhere else.
On a side note, La Push has really awesome shorelines. The waves crash into the rocky jettys with such a force that anyone out there would get swept away. The wind howls off the sea beckoning your closer and the wisps away your hat or tosses your hair from it's hair tie and whispers for your to let go and be free. Ok maybe that's a small exaggeration but the post office is well kept like the entrance to the city. The look of things trails off a bit as you get deeper in but I'd come back just to see the water and mail some postcards. read more
