If you have one weekend in Perthshire and want to combine road cycling with two Munros, the answer is Loch Rannoch and Glen Lyon. The route is compact, the roads are quiet, and the hills sit close enough to the valley floor that you can ride to the trailhead, summit, and ride back before dinner. This article explains exactly how to do it, what gear you need, and where most people get stuck.
Why This Specific Weekend Works
Loch Rannoch runs roughly east-west for 16 km. Glen Lyon cuts north off the loch’s western end. Together they form a T-shaped corridor of low-traffic single-track roads with two major Munros — Schiehallion (1,083 m) and Ben Lawers (1,214 m) — within cycling distance of the same base. Most Munro-baggers drive to a car park, walk, and drive home. That misses the point. Cycling to the hill adds a warm-up, a cool-down, and turns a single summit into a full-day physical challenge.
The 2026 season saw a 40% increase in visitor numbers at Ben Lawers car park according to National Trust Scotland. That means parking fills by 8:00 AM on summer Saturdays. By cycling from a village like Kinloch Rannoch or Bridge of Balgie, you bypass the queue entirely and arrive with legs already warm.
The Core Route in Numbers
Base: Kinloch Rannoch (elevation 210 m). Saturday: ride to Braes of Foss car park (20 km, 350 m climbing), summit Schiehallion (3–4 hours round trip on foot), ride back. Sunday: ride to Ben Lawers car park (25 km, 500 m climbing), summit Ben Lawers (4–5 hours on foot, optional second Munro Beinn Ghlas en route), ride back. Total weekend cycling: ~90 km with ~1,500 m elevation gain. Total walking: ~16 km with ~1,200 m elevation gain.
Gear You Cannot Skip
This is not a supported tour. There is no bike shop between Kinloch Rannoch and the Glen Lyon road end. If your chain snaps or your brake pad disintegrates, you walk out. Here is the minimum kit list, tested over four repeat weekends in 2026 and 2026.
Bike Setup
An endurance road bike with 28 mm tyres minimum. The Glen Lyon road is tarmac but has gravel patches, sheep dung, and the occasional pothole deep enough to crack a rim. Giant Defy Advanced 2 (2026, ~£2,400) or Trek Domane SL 5 (~£2,800) both fit 32 mm tyres without modification. Fit those. Run tubeless at 50–55 psi front, 55–60 psi rear. That absorbs vibration on the descent from Ben Lawers without sacrificing rolling speed on the flat lochside sections.
Carry These
- Two spare inner tubes (tubeless can still burp and lose all air)
- Multi-tool with chain breaker (Park Tool IB-3 or similar)
- Quick-link for your specific chain width (11-speed or 12-speed)
- Mini pump with gauge (Lezyne Pocket Drive HV, ~£35)
- Front light and rear light (Exposure TraceR, ~£60) — the Glen Lyon road has no streetlights and no phone signal for long stretches
- GPS unit or phone with offline OS Maps downloaded (ViewRanger or OS Maps app)
Do not rely on phone battery alone. Cold temperatures and GPS drain a phone in under 4 hours. A Garmin Edge 540 (~£280) lasts 20 hours and shows the route even in fog.
The Saturday Itinerary: Schiehallion
Schiehallion is often called the “Matterhorn of Perthshire” for its sharp, symmetrical cone. From the Braes of Foss car park, the path is a well-maintained but steep 3.5 km each way with 700 m of ascent. Most walkers take 3–4 hours round trip. You will be slower if you cycled 20 km to get there.
Timing Window
Leave Kinloch Rannoch at 07:00. The ride to Braes of Foss takes 60–70 minutes at a steady pace. Lock bikes at the car park (bring a D-lock; there are no theft issues reported but it costs nothing to be careful). Summit by 10:00. Descend by 11:30. Ride back to Kinloch Rannoch by 12:30. That leaves the afternoon free for a pub lunch, a swim in the loch, or a short ride to the Dunalastair Water circuit (8 km, flat, gravel path).
One common mistake: thinking the descent from Schiehallion is easy. It is steep, loose in sections, and crowded on summer weekends. You are tired from the morning ride. Walk the steepest 200 m near the summit. Your knees and your next-day ride will thank you.
The Sunday Itinerary: Ben Lawers
Ben Lawers is taller than Schiehallion and the route is longer. The National Trust Scotland visitor centre car park fills early. If you cycle, you park for free at Bridge of Balgie (public parking area, no charge) and ride the 8 km uphill to the trailhead. That adds 250 m of climbing to your bike leg but saves the car park fee (£5 per day) and the stress of finding a space.
Route Details
From Bridge of Balgie, ride east on the Glen Lyon road. The gradient is steady at 4–5% for the first 5 km, then flattens. Lock bikes at the Ben Lawers car park or at the trailhead gate if the car park is full. The path climbs steeply from 400 m to 1,214 m over 4 km. Add Beinn Ghlas (1,103 m) as a ridge walk on the way up — it adds 1 km and 100 m of ascent but gives you two Munros for one day. Total walking: 10 km, 5–6 hours.
Descend carefully. The path is rocky and wet even in dry weather. By 15:00 you should be back on the bike. The ride back to Bridge of Balgie is mostly downhill — 20 minutes if you take it easy, 12 if you push. Do not push. You are tired, the road is narrow, and a car coming around a blind corner cannot stop in time.
Where People Fail
Over four weekends running this exact itinerary, I saw the same mistakes repeat. Here they are, with fixes.
| Mistake | Consequence | Fix |
|---|---|---|
| Starting the bike ride too late (after 08:30) | Heat exhaustion on the hill, car traffic on the narrow road | Leave by 07:00. Set an alarm. Eat breakfast on the bike. |
| Wearing road cycling shoes on the hill | Slipping on wet rock, blisters | Carry trail running shoes or approach shoes in a small backpack. Swap at the trailhead. |
| Not refilling water at the lochside | Running dry on the summit ridge | There are no taps on the hill. Fill bottles at Kinloch Rannoch public toilets or the Bridge of Balgie car park. |
| Attempting both Munros on Saturday | Sunday ride becomes a sufferfest, risk of injury | One per day. This is a weekend, not a race. |
When Not to Do This Weekend
This itinerary is not for everyone. If any of these apply, choose a different plan.
- You are new to cycling. 90 km with 1,500 m of climbing is a solid intermediate ride. If your longest ride in the last month is under 50 km, you will struggle to enjoy the hills.
- You have a gravel bike but no road bike. Gravel tyres add 10–15% rolling resistance on tarmac. The Glen Lyon road is tarmac. You will work harder for no benefit. A road bike with 28–32 mm tyres is the right tool.
- You are carrying a 5 kg backpack. That weight on your back for 90 km of cycling will cause shoulder and lower back pain. Use frame bags or a saddle pack instead. Keep total pack weight under 3 kg.
- You want a relaxed weekend. This is a structured, physical plan. If your idea of a good weekend is reading by a fire, book a cottage in Aberfeldy and skip the hills.
Alternatives That Add Value
If you have done Schiehallion and Ben Lawers before, or if the weather forecast is terrible, here are three alternatives within the same region.
Alternative 1: The Rannoch Loop (60 km, 800 m climbing)
Start at Kinloch Rannoch, ride west along the north shore of the loch to Rannoch Station, then south on the B846 to Bridge of Gaur, and back along the south shore. This is all tarmac, almost no cars, and you pass the Rannoch Moor viewpoint. No Munros, but the riding is superb. Add a short hike up Beinn a’ Chuirn (885 m, a Corbett) from the Rannoch Station car park if you need a hill fix.
Alternative 2: Glen Lyon Hill Run (15 km trail run, 900 m climbing)
If the bike breaks or the weather turns, park at Bridge of Balgie and run the Ben Lawers path as a fast hike. Carry trail shoes and a waterproof jacket. You can summit Ben Lawers and return in under 4 hours at a steady run-walk pace. No bike needed.
Alternative 3: The Loch Tay Circuit (50 km, 600 m climbing)
Cycle from Killin east along the south shore of Loch Tay to Kenmore, then back on the north shore. This is busier than Glen Lyon but has cafes and bike shops in Kenmore if you need mechanical support. Add a walk up Ben Lawers from the north side (start at Edramucky car park) if you want a hill.
The weekend described here is repeatable, measurable, and avoids the worst crowds. It demands preparation but rewards with two quiet summits and a bike ride that connects them. The best version of this weekend is the one where you finish on Sunday afternoon, sit at the Kinloch Rannoch Hotel with a pint, and feel tired in a way that only comes from moving through a landscape under your own power. That feeling does not depend on the weather or the summit views. It depends on showing up with the right gear and a plan that works.
