Distances below refer to the main route walked over a 7-day itinerary. If you have only 6 days, the easiest way to save a day is to bypass Callander, saving 2.6 miles and leaving a 16.4-mile day (26.4 km) from Aberfoyle to Strathyre. Note that using the Glen Quaich alternative increases the distance from Ardtalnaig to Aberfeldy to 30.4 miles (49 km).
