Myself and my husband did the 9km trek. It was a lovely day, hot with clear blue skies. We got there for 0930 and the car park was already full but we were one of the first to park on the road so that was ok. It only took us 2hrs 45 mins to do the 9km walk, but we are experienced walkers and scramblers and dint stop for a swim. We saw seals and there were quite a lot of ants so be aware of this. With trainers on though the ants were not a problem. Lovely views and a nice interesting walk.
