The Glen Loin Loop is a mountain biking route that typically takes around 1 hour and 43 minutes to complete. This duration is for the 16.9 km (10.5 miles) loop, but actual times can vary based on your fitness level and how often you stop to enjoy the views.
The terrain on this loop is diverse and challenging. You'll encounter a mix of surfaces, including steady climbs on fire roads with expansive views, and significant sections of 'quality' singletrack through the forest. Some singletrack parts can be technical and rough, especially the Glen Loin path which is also popular with walkers and may be eroded. Expect steep climbs and descents, including a sweeping 3.6 km descent after a stream crossing.

Other highlights include the Glen Loin Trail itself, a Stream Crossing in Loch Lomond and The Trossachs National Park, and a View of Loch Lomond.
