Meikle Bin, Carron Valley Reservoir and Haugh Hill Loop

This medium-grade loop in the Campsie Fells combines a steady hill ascent with long reservoir-side stretches, giving a varied day out of roughly 14 km / 8.7 miles with around 400 m / 1,312 ft of climbing. Expect a mix of forestry tracks, open hillside paths, wetter ground higher up, and broad views over Carron Valley Reservoir once you break out of the trees. Meikle Bin itself rises to about 570 m / 1,870 ft and is one of the most prominent summits in this part of central Scotland, so although the route is not especially technical in dry, calm weather, it can feel much more serious in wind, mist, or after prolonged rain.

The usual start for this loop is the small parking area at the western end of Carron Valley Reservoir, opposite or near Todholes on the B818, west of Denny. A practical nearest landmark/address description is the Meikle Bin car park at the west end of Carron Valley Reservoir, near Todholes, B818, Stirling council area, Scotland, rather than a formal street address. Forestry and Land Scotland identifies this as the favored starting point for Meikle Bin, and Walkhighlands places the start at the north end of the reservoir at Todholes on the B818.

By car, the B818 is the key access road, with the trailhead reached from the Carron Valley side of the reservoir. Parking is limited, and Forestry and Land Scotland notes that parking in front of barriers or blocking access is prohibited because this is a working forest area with vehicle access needed at all hours. If arriving by public transport, there is no widely advertised direct service to the trailhead itself, so most hikers should expect to travel by rail or bus to a larger nearby town such as Denny, Stirling, or Glasgow-side connections, then continue by taxi for the final stretch; checking current connections on Traveline before setting out is the safest approach.

The opening section is usually the easiest underfoot. From the car park, the route heads along forestry track beside the reservoir and through commercial woodland. Early on, gradients are gentle, making this a good place to settle into the walk before the climb begins in earnest. Around the lower tracks you can expect views across the water, glimpses of the River Carron, and a sense of the scale of the surrounding plantation forest. Carron Valley Reservoir itself was opened in 1939 and supplies drinking water to roughly 135,000 people in the Forth Valley, which gives the landscape a strong engineered character alongside its upland scenery.

Climbing toward Meikle Bin

After the lower forest roads, the route turns uphill and begins the main ascent. This is where the walk earns its medium rating. The climb is not a scramble, but it is sustained, and the transition from track to hill path can be muddy or boggy, especially where the route leaves the shelter of the trees. Walkhighlands notes steep path sections to the summit, and that matches the general character here: straightforward navigation in clear weather on obvious lines, but less forgiving if low cloud drops over the hill. Using HiiKER to follow the loop is sensible, especially if you plan to descend by a different line rather than simply retracing your steps. (walkhighlands.co.uk)

As height is gained, the views open quickly behind you. The reservoir becomes the visual anchor of the route, with the surrounding forestry blocks, rolling farmland, and neighboring hills spreading out below. On clearer days, sources note views extending to hills such as Ben Lomond and Ben Ledi, while the summit itself is marked by a trig point. The final approach can feel longer than expected because the top stays hidden until quite late, so pacing matters on the upper slopes. (walkhighlands.co.uk)

Reservoir, woodland, and wildlife

The loop’s appeal is not only the summit. Carron Valley is promoted as a landscape rich in wildlife, and the mix of reservoir edge, conifer forest, open hill, and patches of more natural habitat supports a good range of species. Forestry and Land Scotland highlights red squirrels and crossbills in the woods, with ospreys and other waterbirds around the lochside; its land management material also notes pine marten in the wider forest area. That means hikers should keep an eye on the treetops and quieter woodland edges as much as on
