Up to Lagganlia Outdoor Education Centre yesterday ... very similar issues raised (obviously!) and discussed as when I recently visited Benmore.
Being a Friday, didn't meet any activity groups - all had just left - and thus was spared the gorge walk experience this time ;-)
Did get a bit more time to meet and talk to staff, and I certainly found both this trip - and the earlier one to Benmore - enormously useful. Hope the staff felt it worthwhile also!
