One of the 29 routes designated by NatureScot as Scotland's Great Trails — largely off-road, well-managed long-distance routes that are signposted and mapped end to end.
How long it really is
We measure Three Lochs Way at 54 km (33.6 miles), computed by walking the OpenStreetMap route geometry point by point . The route is tagged in OpenStreetMap as 52; where that differs from our figure, the difference is usually alternative sections, spurs, or a published distance that rounds.
This is horizontal distance only. Our trail dataset carries no elevation profile, so we will not quote a total climb or a confident walking time — on hill routes ascent can add hours a day. A flat-ground pace gives roughly 12 h 31 min of walking for the whole route, which is a floor, not an estimate. Add your own ascent figure in the walking-time calculator for something usable.
Access rights along the way
The route stays within Scotland, so one access regime applies along its length.
Scotland
Yes Right to roam: Statutory right of responsible access to most land and inland water.
Yes Wild camping: Wild camping is broadly lawful under the 2003 Act.
In defined Camping Management Zones (roughly 1 March – 30 September) camping requires a permit or use of a designated site, despite the general Scottish access right. Zones cover parts of east Loch Lomond, Trossachs lochshores and other honeypot areas.
A waymarked route is a route you may walk — it does not follow that you may camp beside it, leave it, or take a dog on it. Long-distance paths cross farmland, estates and access land in turn, and byelaws and seasonal restrictions override the general position. This is general information, not legal advice. Check a specific spot with the access checker.
National parks on the route
The line passes through one national park, each with its own byelaws and camping position.
Summits on and beside the route
Listed hills from our hill dataset whose summit lies within 2.5 km of the line — none of them directly on it. Distances are measured from the nearest point of the path, not from a trailhead.
| Summit | Height | From path | Lists |
|---|---|---|---|
| Cruach an t-Sidhein | 683.6 m | 1.5 km | GrahamMarilyn |
| Tullich Hill | 633.1 m | 1.7 km | GrahamMarilyn |
| Beinn a' Mhanaich | 709 m | 2 km | GrahamMarilyn |
The route in day stages
Three Lochs Way cut into 3 stages of roughly 20 km, measured along the line itself. These are equal-distance splits computed from the geometry, not an official itinerary — they will not always land on a village, a bunkhouse or a station, and the real day you walk should be set by where you can sleep.
OpenStreetMap does not hold Three Lochs Way as one continuous line, so the stages below run through the pieces in order of length and the joins between them are not walking distance. Treat the stage boundaries as approximate, and check the official route for the sections between them.
| Stage | Distance | Cumulative | Starts near | Ends near | Flat-ground time |
|---|---|---|---|---|---|
| 1 | 20.8 km | 20.8 km | NS 3904 8193 | NS 2888 8877 | 4 h 35 min |
| 2 | 20.9 km | 41.7 km | NS 2888 8877 | NN 3082 0403 | 4 h 36 min |
| 3 | 11 km | 52.7 km | NN 3082 0403 | NS 3324 8210 | 2 h 25 min |
Positions are 8-figure (100 m) OS grid references for points on the line, computed from WGS84 coordinates. Flat-ground times are Naismith at 5 km/h with a 6 min/hour rest allowance and no ascent — add the climb in the walking-time calculator before you plan around them.
