It is an easy 11km walk along the beaches and headlands of the coastline from Port Macquarie CBD to Tacking Point Lighthouse. It can be walked in shorter sections with lots of access points and carparks at beaches and lookouts and there are even local buses which stop at either end and enroute.
I kept walking south from Lighthouse Beach to Lake Cathie where my parents drove up to meet me. There is a picture of Dad walking up the beach. It was a stinking hot day and hard work on the soft sand at high tide but worth every step.
