Here are three excellent scenic drives through the The Trossachs (Scotland) — each with clear route, highlights and a risk-check. You can pick the one that suits how much time you have and how deep you want to go. You’ll find winding roads, lochs and forest views across The Trossachs; best to allow extra time for stops, check seasonal access, and drive carefully on narrow passes.

1. Duke’s Pass (A821) Loop (Callander ↔ Aberfoyle ↔ Brig o’ Turk)
Check out some images of the Duke’s Pass here
Route & highlights
- Start at Callander → take the A84/A821 (Kilmahog) up the Duke’s Pass to Aberfoyle → continue to Brig o’ Turk.
- You’ll climb through forest, ridge views, and down to lochs — e.g., Loch Achray.
- Near the pass: parking lay-bys and viewpoints.
Why it’s good
- Short to moderate length (≈ 26 miles if full loop).
- Classic Trossachs scenery: lochs, hills, woodlands.
- Good if you want one strong route without too much detour.
Risk / things to check
- Narrow roads, winding sections: drive slowly.
- Weather can change quickly (mist, slick roads).
- Some parking/viewpoints may fill up.
- In winter or shoulder season parts may be tricky (icy, or snow).
2. Three Lochs Forest Drive (one-way forest route)
Images of the drive can be found here.
Route & highlights
- Access via Duke’s Pass/A821 north of Aberfoyle: enter the one-way forest drive (≈7 miles) through remote woodlands and three lochs: Lochan Reòidhte, Loch Drunkie, and Loch Achray.
- Stops: short sign-posted walks at each loch (e.g., Little Drunkie Trail ~¾ mile).
- Wildlife possible: deer, red squirrels, birds.
Why it’s good
- A more “off-beat” option: forest, quieter lochs, less traffic.
- Great for combining with a main route (e.g., loop above).
- Gives you a chunk of peaceful nature.
Risk / things to check
- Access seasonal: open “Easter to 1st October” daily, 9am-4pm for vehicles. Outside these times you may walk or cycle. Visit Callander Visitor Information Centre for more details.
- Being one-way: you must follow direction, plan your exit.
- Facilities limited: no major stops within drive.
- Narrow forest road – slow going, be mindful of cyclists/pedestrians.
3. Classic Loch & Valley Drive
Loch Katrine, Loch Venachar, Loch Voil Route & highlights – views of lochs, hills, tree-lined shores.
- Use the A821/Duke’s Pass route then detour up around Loch Katrine and along loch-side roads. Visit trossachs.co.uk for more information and images.
- Option to stop: scenic boat/sightseeing on Loch Katrine.
Why it’s good
- Offers that “classic Scotland loch & mountain” feel.
- Good if you’d like the drive + time for stops along shores.
- Works either as a dedicated outing or part of a longer outing.
Risk / things to check
- Some roads may be single track or tricky passing places.
- Weather and daylight: loch-side roads can be slippery.
- If you’re detouring off main roads, services may be fewer.
At-a-Glance Comparison
| Route Name | Approx Length* | Traffic & Access | Best For |
|---|---|---|---|
| Duke’s Pass Loop | ~26 miles (loop) | Moderate | A strong standalone scenic drive |
| Three Lochs Forest Drive | ~7 miles (one-way) | Lower traffic, seasonal | Quiet nature + forest immersion |
| Loch Katrine / Loch Venachar-Voil | Variable (30+ miles) | Variable – some narrow road | Loch-side scenery + stops |
*Approximate — depends on your exact start/finish/side-trips, but given the scenery, if you are taking photos, then you need to allow quite some time.
