Estimated Times to Run







From the carpark the route takes a path down to the dunes and turns north to the mouth of the Lagoon. You may get your feet wet here. Steps take you up onto the top of the cliffs where a path between a deer fence and a thin strip of plantation continues with a series of undulations along the cliffs. In places you have to pick your way through tree branches.

This path will eventually drop onto Shag Beach and you can follow this to the Shag River mouth. [At low tide it is possible to drop onto the beach early [Look at the gpx track.] Once at the Shag River, rejoice in the splendour of the isolation, try not to get chased by sea lions and the re-trace your steps back to the start!

Spectacular views as you run along the cliffs.
Lots of nesting seabirds as well as sea lions on the beach section
You probably won't meet another person on this route...

Lightweight fleece top, Long-sleeved thermal top, Seam-sealed waterproof jacket, Gloves, Beanie/thermal headwear, Whistle, First aid kit, Extra food for emergencies, Cellphone, Map

You cross a few streams but these all drain off farmland so I would use it as a last resort and definitely treat it before drinking.

Plan to do this at low tide.

Track is very overgrown! But a fun adventure anyway. We crawled under a lot of stuff 🤦🏽‍♀️ We got about 600m from the end but 3 big seals were blocking the beach and we couldn't get through the trees.

Neat to go check out this little piece of coastline. I would have given an extra star but I stood on the only dogshit in the area as soon as I got out of my car.
