I'd like to spend 1/2 day in the Cairngorms. I'll be coming from Dufftown. I'm most interested in scenery, a 1-3 mile walk, and wildlife spotting. It appears that Tomintoul is closest. Would it be best for me to explore from there? Or, should I route around to Aviemore. Are there areas and sights you recommend? Is 1/2 a day reasonable? Thank you.
