This spectacular coastal walk is officially 11.4 km and takes 3hr 40min. For me, it took longer, since I always stopped to enjoy a view, or a wildflower, to take a photo of a fascinating rock formation, etc. The walk starts at Collaroy Beach and continues to Long Reef. There enjoy the breathtaking view, and walk through Long Reef Beach, to Dee Why Beach. Next to the rock pool, some unusual looking rocks, like a beehive. From the beach turn up to the Dee Why Hadland walk, leading to Curl Curl beaches, that is a bit steep at the beginning, but the rugged sandstone headland provides you with some unforgettable vista, south to Manly and north to Long Reef and beyond. Arriving at North Curl Curl Beach, walk towards the South Curl Curl Life Saving Surf Club from where the Curl Curl to Freshwater walk starts and ends at the Freshwater Life Saving Club. The boardwalk is an absolute must. After the walkway turns up to the road, don't go straight to Freshwater beach. Just a short break away is the Freshwater lookout, from where you can see the Long Reef in one direction and Manly in the other direction. McKillop Park, with the statue of Duke Paoa Kahanamoku, also, only cca 100 m away. From Freshwater Beach, you can climb over Queenscliff, and see Queenscliff Beach as well. First, I had a glimpse of Manly Lagoon and The Stuart Somerville Bridge, and from there, the ocean and the sandy beach. Now it is very close to Manly already. The next station is North Steyne, which is practically part of Manly Beach. This walk following the coastline is so spectacular that you feel sorry to arrive at Manly and finish it.
