Lime Craig Trail (4 miles)
The source of the River Forth is close to the small town of Aberfoyle and it is interesting to see the beginning of this mighty watercourse. Turn up the steep Duke's Pass (A821) from the main street - signed for Forest Park Visitor Centre. Negotiate a few twisting bends then turn right into the large car park for the Lodge Centre. This is part of the massive 50,000 acre Queen Elizabeth Forest Park.
There is an exhibition and a café at The Lodge. Four walking trails originate here and more details can be found on this PDF download. We follow the red markers for the Lime Craig Trail which crosses the Highland Boundary Fault.
We pass an impressive waterfall. You may also see people passing high above on a zip wire as this is also the home of the Go Ape high rope centre. Cross a footbridge and continue following the red posts. It is worth taking the short detour to the red squirrel hide where a variety of birds can also be spotted on the feeders - including a nuthatch.
The path climbs up to the boundary fault which is the geographical division between the Highlands and Lowlands of Scotland. There is a signposted leg to a viewpoint which heads up Lime Craig to give a fine outlook across the surrounding landscape. The trail now begins its descent and we loop back round to the Lodge Centre. Back in the town, the Forth Inn offers real ale.
