Old Military Rd. (Inversnaid – Trossachs Pier)

Grading: moderate.

Taking in the three spectacular lochs of Lomond, Arklet and Katrine with views of Ben Lomond, Ben Venue and the Cobbler, this route also has the option of combining cycling with a journey by waterbus for added variety. The route can be done as a one way / return journey or combined with Waterbus services on Loch Katrine (and bookable transport thereafter) to continue your journey into the National Park.

Loch Arklet

Route description

From Tarbet, use the waterbus service to cross the iconic Loch Lomond to Inversnaid. A short (but sharp!) 2km climb from Inversnaid leads to the Old Garrison and RSPB Nature Reserve. From the car park turn right through the gates and follow the Old Military Road alongside Loch Arklet for 6.2km to Stronachlachar pier (cafe and waterbus connection).

If you are feeling energetic, continue riding from Stronachlachar on the shoreline road for 21km around Loch Katrine to the pier. The route has a couple of long uphill hauls, enjoyable sections of freewheeling, and a cornucopia of scenic picnic spots. The road is a private single track and relatively traffic free, however be prepared for the occasional vehicle, other cyclists and walkers.
