Start at either Upper or Lower Mill Street and head downhill towards the River Devon. An information board marks the start of the trail and almost immediately we encounter the tall piers of the dismantled viaduct which lifted the Devon Valley Railway above the water. The line closed to passengers in 1964 and freight rumbled on for a further decade. It's worth making the relatively easy scramble up the embankment path as the extra elevation affords a lovely view of the town nestled at the foot of the Ochils.
Follow the obvious river path until we reach the main road where the famed Sterling furniture warehouse is located and the adjacent shopping village. Take the time to browse should you desire. Several eating options are available here. Head up to the High Street and take a left. We are now back where we began. This time we ascend Upper Mill Street to the foot of Mill Glen. A map is on display and we simply follow the clearly marked route upstream. Sturdy staircases and walkways with banisters have been constructed and this is a very safe climb - albeit a steep one.
The path crosses over the burn half a dozen times before turning back on itself at the final bridge. At this point we have three options. The easy choice is to simply return to the start using the purpose-built stairs. Alternatively, cross the burn and work your way down the other side. This route is rougher and not as well protected. Thirdly, you could choose to pass through an exit gate and follow the path up the mound of Law Hill which is staring you in the face. Aside from some minor rocky scrambling near the beginning, it's a straightforward (although steep) ascent. Amazing views all the way to the River Forth unfold even if you only go halfway up the Law.
PUB STOPS - You will already have walked past The Woolpack Inn on your way up to the glen. Two or three real ales are available in this traditional cosy pub. At the time of writing, no food is available.
