Gilsa Water, Hill of Tongues, South Ham, Town Loch and Birki Waters Loop

This medium-grade loop on Muckle Roe in Shetland packs a lot into roughly 11 km / 6.8 miles, with about 300 m / 985 ft of ascent. Expect a route that feels bigger and wilder than the numbers suggest: rough coastal ground, open moor, lochside stretches, and a strong sense of exposure to weather and sea. The terrain is varied rather than relentlessly steep, but the combination of boggy sections, uneven paths, and intermittent route definition means it suits walkers who are comfortable navigating beyond straightforward waymarked trails. The wider Hams of Muckle Roe circuit published by Shetland.org is 11 km with 378 m of ascent from the road end at Little-Ayre, so this loop sits in that same demanding coastal-moorland character even if your exact line differs slightly. (shetland.org)

The start is near Little-Ayre, Muckle Roe, Shetland, at the end of the public road on the island’s south side. A useful landmark is the small parking area by the road end near West Ayre / Little-Ayre, with the mapped start for the local walking route at grid reference HU 321 629. Muckle Roe itself is linked to the Shetland Mainland by bridge, so there is no ferry involved for the trailhead approach. (shetland.org)

By car, the usual approach is from Brae on Shetland Mainland, following the road west and south past Busta House and across the bridge onto Muckle Roe, then continuing to the road end at Little-Ayre. Shetland.org notes that parking is limited and asks visitors to park responsibly. By public transport, there is a limited bus service serving the walk area, and current Shetland travel information shows departures from Brae to Muckle Roe, but service frequency is sparse enough that checking the day’s timetable before setting out is essential.

Early on, the route typically heads out on a clearer track before becoming more open and less defined. Around Gilsa Water, the walking is quieter and more inland in feel, with the loch giving a calm contrast to the more dramatic coast. From there, the ground rises toward the higher interior around the Hill of Tongues, where the ascent is spread across rolling moorland rather than one single climb. On a day of low cloud or strong wind, this central section can feel serious despite the modest elevation, so waterproof footwear and full weather layers are sensible even in summer. The local route descriptions also note rough metalled tracks and sections where the path becomes less obvious, especially once you move away from the better-trodden approach lines.

Terrain and navigation

This is the kind of walk where underfoot conditions matter as much as distance. You can expect a mix of rough track, sheep paths, peat, heather, wet ground, and stonier sections. Some stretches near the coast and lochs are easy to follow, while others across the hillier interior can be faint or braided. After rain, the boggier ground around the moorland waters and hollows can slow progress considerably. The published Hams route is rated challenging by Shetland.org, which is a useful reminder that Shetland walking often feels tougher than the mileage alone suggests. (shetland.org)

For planning, load the route into HiiKER and do not rely on a single visible path being present throughout. Good visibility makes a major difference here. In mist, the lochs and low ridges can make the landscape feel repetitive, and line choice becomes more important around wetter ground and less distinct junctions.

Landmarks, scenery, and what to expect

The character of this loop comes from the contrast between inland waters and the coast. Gilsa Water, Town Loch, and the Birki Waters give the route a chain-of-lochs feel, while the nearby Hams coastline is known for small bays, headlands, sea stacks, and striking red rock. Shetland.org describes the Hams as small bays fringed by red granite cliffs and sea stacks, and independent route notes mention the stillness of Gilsa Water before the landscape shifts back
