Hi Bev & Mandy,
The road in the 1st photo is off the main road behind the Ozlam 1. Head inland then back on yourself up the road in the photo, when you get almost to the top,(there is another larger gate) you will see markers on your left for the climb to the flag. Looking at Google maps, you may be able to climb directly from the Ozlam 1, crossing over the road and continuing the climb to the Flag....
Just one note.....If anyone is thinking of climbing to the Flag, please bring your water bottles, or any other litter back down with you. Don't spoil what is a natural Beautiful Landscape with discarded rubbish....
