Start at the public car park beside Trossachs Pier and walk past the pier facilities onto the north shore road. Keep Loch Katrine on your left as the road winds through oak woodland and around small bays. Follow the Brenachoile Trail signs, staying on the shore road where the Primrose Hill route branches uphill. At Brenachoile Point, take the short grassy path to the viewpoint, then return by the same shore route.
Allow about two and a half hours, including a stop at the point. Most of the walk uses a wide, smooth tarmac road with moderate slopes. The final viewpoint path is uneven grass with a short, fairly steep slope, so it can be slippery after rain. This is a lochside walk without a summit ascent. The road is shared with cyclists and occasional authorised vehicles; keep alert at bends and leave room for others to pass.
The shoreline gives changing views across the water towards Ben Venue and the wooded Trossachs hills. Book-shaped information panels explain the landscape's links with artists and writers, including Sir Walter Scott and The Lady of the Lake. Brenachoile Point is a natural place to pause before retracing your steps. Keep children and dogs close by the water and stay on the established path.
Trossachs Pier has toilets, a cafe, shop and cycle hire. The public car park is reached from the signed Loch Katrine turn off the A821, rather than the separate pier at Stronachlachar. Parking is charged and the operator accepts cash or card here; check the tariff and any closing signs on arrival. Bring waterproofs and check Forestry and Land Scotland notices before travelling.
