We've been hearing lots of good things about a local tour company, RAW Travel, based in Mornington. They can organise itineraries and accommodation bookings right through to taking guided tours on the Camino (and lots of other local and overseas destination as well). They can organise both walking and cycling Caminos.
A number of people we've met through our Camino workshops have sung RAW Travel's praises so we feel pretty comfortable recommending them.
