At the carpark in Glencoe you can just glimpse the narrow wee glen that leads up to the Hidden Glen. 

If you click on the Hidden Glen link above you will find all details re map references etc. There is one part where the path is very narrow with a big drop to one side- sturdy boots and a good grip on children required! Further on the path is as below.

The large rock at the entance, where all kids will go!
