This is a terrific ride and so close to the Big Smoke. The map looks right to me as there is a 1km stretch that is on the Seacliff Bridge which is one of the few bridges in the world which is built on pylons over the ocean. This alone makes the ride worthwhile but the twists through the park are a gass as well. Have a blast!
something wacky happened with the mapping if this ride. riding through the ocean for a while? :p
I recommend remaking the path.
Route 68 runs from Sydney through the Royal National Park and along the Pacific coast to Wollongong.
It is a very recommendable ride which varies between twisty, hilly roads in the quite deserted but beautiful park area and the luxury feel of the sweeping bends and stretches along the residential coastline south of the Park leading to Wollongong.
Ride safely - but have fun...! :o)
