The A77 is not for cycling. It carries the Irish ferry traffic, it is narrow and fast south of Girvan, and there is no shoulder. Turn inland, though, and within two miles you are on some of the quietest lanes in Scotland — valley roads where you can ride for an hour and meet a tractor.
Road loops
- The Girvan valley loop, 22 miles. B741 east to Dailly, over to Barr by the B734, and back down to Girvan. Rolling, scenic, one steady climb, and past three castles. The best introduction to riding here.
- The Stinchar valley, 35 miles. Girvan–Pinwherry–Colmonell–Ballantrae, returning on the A77 or, better, reversing the outward route to avoid it. Castles and a salmon river the whole way.
- The Nick of the Balloch. Barr to Glentrool over the pass — fifteen miles of single-track moorland road climbing to around 1,280 feet, and one of the best rides in the south-west. Exposed, no shelter, and nothing at the top but the view.
- The Carrick Forest Drive (gravel). Straiton–Stinchar Bridge–Loch Bradan–Loch Doon, seven miles of forest road with big climbs. Seasonal and can close — check first.
- National Cycle Route 7 passes through Girvan on its way from Ayr to Stranraer, using the coast road and lanes.
Mountain biking
Glentrool and Kirroughtree are two of the 7stanes trail centres, 45 to 55 minutes from Girvan. Graded trails from green family loops through blue and red to Kirroughtree's black Black Craigs, with a skills loop, bike hire, a bike wash and cafés at both.
Kirroughtree has the bigger reputation and riders travel a long way for it. If you have never ridden a trail centre, the green and blue routes are genuinely approachable.
Hire
Biosphere Bikes operates on Girvan promenade, principally summer weekends — good for the flat prom and the valley lanes. Kirroughtree hires proper mountain bikes on site.
Practical notes
The inland lanes are single track with passing places in stretches, and used by farm and timber traffic — timber lorries in particular are wide and quick. There is no fuel, no shops and unreliable mobile signal on the Nick of the Balloch or the forest drive. Carry tools, food and water; the nearest help can be a long way off.
Gradients here are real. The valleys are gentle but every route out of them involves a climb, and the moorland roads are exposed to a wind that is usually westerly.
