Lochan Beinn Chabhair, Parlan Hill, Creag Bhreac Mhor and Beinn Chabhair

This is a tough, rough hill day in the northern part of Loch Lomond & The Trossachs National Park, taking in Lochan Beinn Chabhair, Parlan Hill, Creag Bhreac Mhor and the main summit of Beinn Chabhair. Expect around 13 km / 8.1 miles with roughly 1,000 m / 3,280 ft of ascent, which is a serious amount of climbing for the distance. The outing is best thought of as a steep mountain circuit with a punishing start, wet moorland in the middle, and a rocky Munro finish. The usual access point is Inverarnan, near the Drovers Inn and Beinglas Farm Campsite, both at Inverarnan, Arrochar, G83 7DX, just off the A82. (walkhighlands.co.uk)

The route begins low beside the glen and quickly commits to a very steep pull next to the Ben Glas Burn. This lower section is often the most physically abrupt part of the day, climbing hard on a stony, worn path beside striking waterfalls. Even early on, the terrain gives a clear warning of the character of the hike: this is not a gentle warm-up, and in wet weather the path can be slick, eroded, and tiring underfoot.

As height is gained, the route opens onto rougher upland ground around Lochan Beinn Chabhair. This small lochan is one of the key landmarks of the day and helps break the climb into distinct stages. Around here, the ground tends to become softer and boggier, with less obvious trods in places. If cloud is down, this middle section can feel confusing because the terrain broadens and the line onward toward Parlan Hill and Creag Bhreac Mhor is less defined than the lower path. Careful navigation is important, and if you are carrying digital mapping, HiiKER is the tool to rely on for checking your line across the moor and onto the higher ridges. (walkhighlands.co.uk)

Terrain and route character

Parlan Hill and Creag Bhreac Mhor add shape and interest to the outing rather than feeling like separate major summits. They sit as intermediate high points and shoulders on the way toward Beinn Chabhair, giving changing angles back over the lochan and outward toward the surrounding hills. Distances between these features are not huge, but the ground can make progress slower than the map suggests. Short peat hags, wet patches, and uneven grassy shelves all sap energy, especially after rain. (themountainguide.co.uk)

The final approach to Beinn Chabhair is more mountainous in feel. The summit area is known for craggy outcrops and a more intricate line of ascent, where walkers typically work around rocky ribs rather than simply marching straight uphill. The summit itself stands at 933 m / 3,061 ft, making it a Munro, and the views can be extensive in clear weather, with Loch Lomond visible to the south and a broad spread of West Highland peaks around the horizon.

Descent usually retraces or loops back over the same broad upland ground, so energy management matters. On paper, 13 km / 8.1 miles may not sound especially long, but the combination of steep ascent, wet ground, and route-finding makes it feel much bigger than the mileage suggests. Strong boots, full waterproofs, spare warm layers, and enough food and water for a long mountain day are sensible essentials here. In poor visibility, this is not a place to rely on faint paths alone. (walkhighlands.co.uk)

Landmarks, wildlife, and what to look for

One of the most memorable natural features is the Ben Glas Burn and its waterfalls near the start. Higher up, Lochan Beinn Chabhair gives the route a quieter, more remote feel before the ridge and summit ground become rockier. The mountain’s name is often interpreted as “hill of the hawks” or “hill of the antler,” and the latter is fitting given the regular presence of red deer on these slopes. Golden eagles are never guaranteed, but raptors and other upland birds are part of the wider ecological character of the area. (lochlomond-trossachs.org)

The landscape is classic West Highland mountain country: steep-sided burns, open moor, craggy upper slopes, and broad views over glens shaped
