Have to agree with Moey....the views back down onto the Glenquickan circle are great.
Beware of trying to shorten the journey back to the car park next to the bridge, the ground is very boggy....try it and you might get to sample the delights of trenchfoot.
The cist and its graffiti covered cap stone are worth seeing.....and it's only a short walk from the circle.
The Cist lies above Glenquickan Stone Circle roughly to the South West. It is close, but not visible from the circle. Watch out for the bog - you'll get sucked in & never seen again.
I didn't spot it the first time I visited Glenquickan, but it is easy to find as I found out this March. You get a great view of Glenquickan Circle from up there too.
This area has a wealth of Sites just waiting to be explored - I have to go back this summer.
