Hi, I'm from the area, my Granny was from Glen Lyon.
Let's face it, the main draw of Highland Perthshire is the scenery, at least you know that will be open.
Great walks, up to the Falls of Bruar from House of Bruar.
Blair Castle,
Salmon Ladder & Dam
Queen's view
Killiecrankie Battle Site (NTS),
Moulin Brewery,
Black Castle of Moulin (ruin)
Edradour Distillary
Pitlochry pitch & putt
Pitlochry "shows" (funfair, may not be open)
Around Aberfeldy:
Dewars World of Whisky
Aberfeldy Cinema (The Birks Picture Hoose)
Birks of Aberfeldy walk
Highland Wildlife Safari
White water rafting
Castle Menzies (rhymes with mingers)
Loch Tay & Kenmore Beach (yes, we have beaches in Perthshire)
Scottish Crannog Centre
Ben Lawers Visitor Centre
Fortingall Yew
(The road through Glen Lyon above the Pass is very narrow and twisty and there are LOTS of cyclists so drive carefully. Having said that also please be aware that the vehicle behind you may be a local so be prepared to pull over and let them past).
Loads of other walks for all abilities, my DM's hobby was dragging me up hills on a Sunday and I think I first went up Schiehallion when I was about 8. It's not a hard climb, just long.
I wish I was there now, enjoy. If you visit Aberfeldy have a drink in The Blackie for me.
