Hello all - new to the site and hoping to get some 'top tips' for a trip i have booked for July 23 with the following route planned - I am after some advice on 'must see' places / stop offs / cafes etc along the way from people who have experienced the trip and also anything else in general from people who have done the trip and things they did right and things they wished they had done. Much appreciated in advance.
