Where my family used to holiday was called the kullkyne National Park. It was kind of desert like. We had to bring everything including our own portaloo which we had to make ourselves.
Hope you have an amazing trip - its a shame you are so close to the great white north and not able to pop in for a visit.... Well, if things change by the time you hit Washington state, hop across and visit Wreck Beach in Vancouver (weather permitting) its one of my favourite spots to drop my gear and soak up the rays. Safe travels and keep us posted. CC2496
