The Cape Wrath Trail is widely considered the toughest long-distance walk in Britain: roughly 370 kilometres (230 miles) from Fort William to the Cape Wrath lighthouse at the northwestern tip of mainland Scotland. Unlike the waymarked trails of the south, much of this route is pathless — open peat bog, moorland and river valleys where solid map-and-compass navigation is essential, and your phone GPS is a backup rather than a primary tool. It is a walk for competent, experienced backpackers, not a first long-distance route.
This guide covers the route, the key practicalities — resupply, bothies, the military range at the end — and when to go. It is written from consolidated reports by experienced walkers.
The route and how long it takes
Most walkers take 14 to 21 days, moving generally south to north and finishing at the lighthouse. Fit, fast hikers sometimes finish in 9 to 11 days, but that is genuinely quick — plan for two to three weeks, with contingency days for bad weather. The trail threads through some of the emptiest country in Britain: the Ullapool to Kinlochbervie stretch can mean up to five days without a village, and escape routes are limited. The named villages on the route — Shiel Bridge, Strathcarron, Kinlochewe, Ullapool, Inchnadamph, Rhiconich, Kinlochbervie and Durness — are your bail-out and resupply points, so know where they sit on your itinerary.
Because the route is unmarked, poor visibility can slow you dramatically. Walkers consistently say navigation, river levels and weather — not fitness alone — dictate progress. Build buffer days in.
Getting there and resupply
Fort William is easy to reach: buses and the famously scenic train run from Glasgow. No permit or registration is needed to start walking. For resupply, expect to carry two to four days of food between stops. Ullapool is the only larger town with a proper supermarket; elsewhere you rely on small village shops at places like Kinlochewe and Kinlochbervie, hostel shops, and hotel meals at spots like Rhiconich and Kinloch Hourn. Many walkers post resupply parcels ahead to Kinlochewe or Kylesku post offices via Poste Restante — check locally whether that service is still offered before relying on it.
Where to sleep: bothies and wild camping
Nights are a mixture of wild camping and Mountain Bothies Association bothies dotted along the route. Wild camping is legal across Scotland under the Land Reform Act 2003, following the Scottish Outdoor Access Code — leave no trace, pitch away from buildings and roads. Bothies are free, unlocked shelters: no booking, no warden, first-come first-served. Bring everything in, leave the place clean, and a small donation to the association is the custom. Hotels and B&Bs exist only in the villages, so on the remote stretches you are fully self-sufficient.
Exiting the trail and the MOD warning
In summer a small passenger ferry crosses the Kyle of Durness from Keoldale, and a minibus runs the MOD track out to the lighthouse. Recent reports put the combined cost around £25 (ferry cash only, minibus by card) — fares change, so check locally. The boat cannot be booked in advance; walkers turn up and queue, while the minibus can be reserved ahead. From Durness, buses continue onward. Out of season the ferry does not run and you must walk back out — typically one to two days to Kinlochbervie or along the track toward Durness.
The final section to the lighthouse lies inside a live military firing range, and this is the one hazard that needs a plan. Check the current firing schedule before entering the last stretch — dates are generally published about a month ahead — and watch for red flags on the ground, which mean entry is prohibited and the area is genuinely dangerous. If the range is active, be prepared to backtrack to Kinlochbervie. Never rely on second-hand reports about when the range fires; verify current status before you go.
When to walk, midges and rivers
April to June is the most widely recommended window: May is statistically drier, days are long, and midges are not yet out. September and October are also good but can be affected by deer-stalking season diversions and military activity at the cape. July and August bring the longest days but peak midge season — the tiny biting insects are at their worst from June to August in still, damp air, and walkers strongly advise carrying a headnet and repellent.
River crossings are a defining hazard of this trail. After rain, streams can become dangerous: the accepted practice is to walk upstream or downstream — sometimes for miles — until you find a shallow, safe crossing, and to be ready to turn back if a river is too high. Carry quick-dry crossing sandals. Drinking water is plentiful from streams and lochs, so bring a filter rather than carrying large volumes.
The trail itself is free — no permits, no camping fees. The main costs are village resupply, the exit ferry and minibus, occasional hostel or B&B nights, and any posted parcels. Walked entirely self-sufficiently, it is one of the cheapest great adventures in Britain — but it demands weatherproof gear, real navigation skill and respect for the remoteness.
