Lewis Hill and North Third Reservoir Loop

This medium-rated loop explores the wooded slopes and craggy escarpment above North Third Reservoir, just west of Stirling, with a route of about 10 km / 6.2 miles and roughly 200 m / 656 ft of ascent as given. The landscape combines reservoir shoreline walking, short steeper climbs, rougher hill paths, and open viewpoints over central Scotland. The area around North Third Reservoir is reached by minor roads west of Stirling, and the usual start is near the lay-bys by the small bridge over Bannock Burn on the road beside the reservoir; that start point is best described as the roadside parking area near the Bannock Burn bridge at North Third Reservoir, west of Bannockburn and Stirling. Scottish Water notes the reservoir is about a 15-minute drive from central Stirling, and Walkhighlands identifies the start as lay-bys near the bridge over Bannock Burn. (scottishwater.co.uk)

Expect the outing to feel more varied than the modest numbers suggest. The lower sections are generally straightforward, but the climb onto Lewis Hill becomes steeper in places, and paths can be muddy, rough, and slippery after rain. Walkhighlands specifically describes steep ascent and descent around the crags, while Scottish Water warns that many paths here are rough and can be muddy. That makes waterproof footwear and a little extra care on the downhill especially worthwhile, even on a relatively short day. (walkhighlands.co.uk)

Getting there

By car, the simplest approach is from Stirling or Bannockburn via the minor roads leading toward North Third Reservoir. Scottish Water’s directions bring drivers from the M80/M9 Bannockburn Interchange via Pirnhall Road and New Line Road, then onward following signs for North Third Trout Fishery, crossing Bannock Burn with the reservoir on the right. Parking is informal rather than a formal trailhead car park, so arrive prepared for limited roadside space and avoid blocking access. (scottishwater.co.uk)

For public transport, this is not an easy trailhead. Scottish Water states there are currently no public transport routes directly to the reservoir, and Walkhighlands also lists none. In practice, the nearest realistic public-transport hub is Stirling, from where a taxi, cycle, or a much longer approach on foot would be needed. If planning the route carefully in advance, HiiKER is the best tool to check the approach roads and overall loop layout. (scottishwater.co.uk)

What the route feels like

The walk usually begins beside Bannock Burn, then heads into woodland on a rising path. Early on, the trees give partial glimpses across the water, and the route gradually builds anticipation before the more open ground above the reservoir. This first section is often the dampest underfoot, especially after wet weather, so roots, leaf litter, and muddy patches can slow the pace. (walkhighlands.co.uk)

As the route climbs higher, the woodland starts to thin and the escarpment of Lewis Hill becomes the defining feature. The crags are the highlight of the walk: rocky, abrupt, and surprisingly dramatic for a relatively short circuit. The path trends along the top with broadening views over the reservoir, surrounding farmland, and the wider Stirling landscape. On clear days, both Scottish Water and Walkhighlands note views toward Ben Ledi, Stùc a’ Chròin, and Ben Vorlich, which gives the route a much bigger-mountain feel than its height alone would suggest.

The descent from the crags is one of the sections to watch most closely. Walkhighlands describes a steep drop in wide zig-zags, and this is where loose ground, wet soil, or tired legs can make footing less secure. Near the escarpment edge, extra caution is sensible in wind or poor visibility. (walkhighlands.co.uk)

Lower down, the route reaches the dam and then circles the reservoir shore. This changes the character of the walk completely: after the elevated viewpoints and exposed crags, the shoreline feels calmer and more pastoral. There are views back to the wooded slopes and rocky skyline of Lewis Hill, plus the reservoir’s islands and quieter waterside stretches. The final section near Bannock Burn is gentler and makes for an easier finish, though muddy ground can still linger here. (walkhighlands.co.uk)
