This by-the-road path to Kernell is really popular with cyclists. The destinations of Kurnell and Cape Solander are really terrific and in cycling terms iconic, thats why this up and back exists on the map. To keep to jigsaw protocols ride around Kurnell in a clockwise manner. The trail is a very wide verge at the side of the road designed for cyclists. But visually the road is very dull and if you go after 10am on a weekend it has way too many cars doing 80+km an hour. During the week it gets worst with trucks thundering by. So don't take your kids on it and if you don't like it go somewhere else. I saw 10 broken bottles in the bike section on the way out. Only one going back in. Would help if you can fix punctures. But if you like riding fast on racing bikes, you probably will enjoy it like all the other cyclists
