Within Trossachs and Loch Lomond National Park, this beautiful forest road forms a 12km one-way loop. It skirts Lochan Reòidhte, Loch Drunkie and Loch Achray, then joins Duke's Pass. Developed areas offer pretty views of Loch Achray and Loch Trossachs. But to see squirrels and deer, you have to walk along one of the marked trails, especially since they are very accessible (except for the steep Pine Ridge Trail). Get out of the car: the kids will love it.
