Donegal Bluestack Mountains Forest Drive
Lost roads through Ireland's last frontier
The Coillte forestry road network threading through the Bluestacks offers some of Ireland’s most remote mountain driving, connecting Lough Eske to the high corries below Lavagh More. The main arterial follows old turf-cutting roads that served scattered mountain settlements until the 1950s — you’ll still find stone foundations and field walls reclaimed by heather and bog cotton. The route climbs through commercial forestry before breaking into open moorland at Crockauns, where the track becomes a technical challenge of ruts, rocks, and bog holes.
Plan on moderate difficulty with some expert sections where the track degrades to twin ruts through deep peat. High-clearance essential, and momentum matters on the bog crossings. Coillte permits aren’t required for recreational access, but respect forest operations and locked gates. Weather changes fast up here — carry warm gear and extra fuel. Best between May and September when the worst bog sections firm up. The payoff is absolute solitude in landscapes that look unchanged since the last ice age.

Frequently asked questions
Can a stock Land Rover Defender or 4Runner run this trail, or does it need mods?
Stock is not enough here. You need a modified 4WD with genuine clearance — lift, all-terrain tires minimum. The forestry tracks cut through boggy mountain terrain that will swallow an unlift'd rig, and recovery points matter because there's no one coming to help.
When is the Bluestack forestry track actually passable?
May through September is your window. Irish mountain weather can turn savage fast, and outside those months expect waterlogged tracks, low visibility, and soft bog conditions that make a hard trail nearly undriveable. Even in summer, check local weather before you go — Atlantic storms roll in without warning.
Do you need a permit or pay any fee to drive Coillte forestry roads in Donegal?
No permit or fee is currently required for the forestry roads managed by Coillte, but access can be restricted without notice for logging operations or fire risk. Check coillte.ie before departure — gates do get locked and there's no ranger to call from the trail.
What's the hardest section and what should I actually be ready for?
The upper mountain sections near the ridgeline are where it gets real — narrow single-track cut into peat bog with no room to pass and soft shoulders that drop away fast. One wrong line and you're axle-deep in bog. Traction boards, a hi-lift jack, and a recovery strap are not optional on this one.
Is there any water or fuel between the trailhead and the end near Donegal Town?
Zero fuel on trail — top up in Donegal Town before you leave, as the route is 18 miles of remote backcountry with no services. Water crossings exist on the route, but treat any water before drinking; dispersed camping is possible but bring everything you need in with you.
