We will have spent the previous day at the Edinburgh castle any suggestions for a more rural and possibly less traveled outing to Glencoe. 3 adults and 3 teenagers not everyone that willing of a hiker.
You can take the long scenic route through Dunkeld or Aberfeldy. In Dunkeld for the non-hikers there is a lovely pub, The Taybank, or you can visit the cathedral. Or you can shop at the Naked Sheep or the jewelry store next door. There are several walks of different levels. You can walk up into the hills a bit or just along the Tay. If you want could choose to stop in Aberfeldy. Non-hikers can visit the great bookshop or visit the Crannog Centre. The walk I would do is the Birks of Aberfeldy. It is lovely. (Note that the Walkhighlands website can be a great resource for your hikers.) (Also, note the Robbie Burns reference for the Birks.)
Another idea would be to find some walks in the Trossachs. The hikers could drop off the non-hikers at Loch Katrine where they can take a boat trip on a steamboat. I have not walked in that area so I can't speak to any specific walks.
