Why This Route Works
The Lock Keeper Trail isn't just a cycle route — it's a journey through working history. For over 250 years, the Shannon Navigation connected towns and brought life to the canal. You'll see the same lock systems that boats used centuries ago, many still operated by hand. The ride itself? Flat, steady, no surprises. Perfect if you're building fitness or just want a peaceful day out.
The route stays close to the water nearly the entire way. You'll pass through quiet villages where you can grab coffee or lunch. We've cycled this route in all seasons, and it's genuinely easy to enjoy — whether the sun's out or you're wrapped up against an Irish wind.

Starting from Athlone
Athlone is a proper town with shops, restaurants, and parking. There's a public car park near the bridge (cost around €2 for the day), and you'll find bike shops if you need last-minute repairs. Start your ride from the canal bank near the 13th Lock — you'll see signs once you're down by the water.
The first 3 kilometres are the busiest part. The towpath runs alongside the main canal, and you'll pass a few moored boats and anglers. Don't rush — there's no pressure to go fast here. The path is well-maintained and clearly marked. You'll start spotting the lock gates after about 15 minutes of easy cycling.
A quick tip: bring water and a snack. Once you leave the town centre, there aren't shops for a while. The sun can get warm on the towpath — there's little shade on the first half of the route.
The Lock Gates & Historic Path
Between Athlone and Shannonbridge, you'll pass through 16 lock gates. Most are automated now, but some are still hand-operated — a living piece of Irish waterway heritage. You don't need to go through the locks yourself (unless you're on a boat). The towpath simply runs beside them, so you'll see the mechanics up close without any fuss.
The middle section of the route is genuinely beautiful. The canal widens in places, and you'll cycle past reed beds where water birds nest. The pace feels slower out here — there's less noise, fewer people, just the sound of your wheels on the path and water lapping against the banks.
This is where the "lock keeper" part of the trail comes alive. Historically, lock keepers lived in small cottages beside the locks, maintaining the gates and helping boats pass through. Some of those cottages still stand — painted in bright colours, looking after the waterway just as they did a century ago.
Rest Spots & Refreshments
The route has several good places to stop and catch your breath. Around the 5-kilometre mark, you'll reach Ballynacargy — a small village with a pub (The Harp Bar) where you can get tea and sandwiches. The pub sits right near the canal, and there's a bench outside if the weather's decent. This is our favourite mid-route stop.
Keep going for another 4 kilometres and you'll reach Clonbonny Lock, where there's a picnic area with benches and bins. It's quiet, scenic, and a good spot to rest for 15 minutes without going into a shop. There's no water here, so fill your bottles before leaving Ballynacargy.
Shannonbridge itself — your end point — has several pubs and a small grocery shop. The town sits right where the bridge crosses the Shannon, and it's been a stopping point for travellers for centuries. It's the perfect place to reward yourself with a proper meal after your ride.
Getting Back: The Return Journey
You've got options for the return. The easiest is to cycle back the way you came — it's flat and familiar, and you've already spotted the good spots to rest. Takes about the same time as the outbound journey. Many people prefer this because there's no navigation stress.
If you're feeling adventurous, there's a quieter route back through country roads. From Shannonbridge, head towards Clodiagh and take the R446 north. It's more rolling (slight hills, nothing steep), and you'll see less traffic. This route adds about 2 kilometres but gives you a different view of the landscape.
Either way, don't rush the return. You've already done the hard work getting there. Take it easy, enjoy the views you might've missed on the way out, and stop for another break if your legs need it.
Practical Tips for Your Ride
Things we've learned from riding this route many times
Weather Watch
The towpath gets muddy after heavy rain. Check the forecast — if it's been raining, the surface can be slippery. Spring and autumn are ideal. Summer can be warm with little shade.
Bike Choice
A hybrid or gravel bike works best — the mix of tarmac and gravel means you'll want wider tyres. A road bike is possible but less comfortable. Make sure your brakes are good for gentle slopes near locks.
Water & Hydration
Bring at least 1 litre of water. There aren't many shops between Athlone and Ballynacargy. A small snack (banana, energy bar) helps maintain energy on the longer middle section.
Navigation
The route is well-marked with signs, but download a map on your phone just in case. The towpath is hard to get lost on — it follows the canal the entire way. Turn-by-turn GPS isn't necessary.
Pace Yourself
There's no race here. Flat terrain is deceptive — you can push harder than you realise and end up tired. Cycle at a pace where you can hold a conversation. Stop whenever you want.
Sun Protection
Sunscreen is essential — the water reflects light and you'll catch more sun than you think. Wear a hat or cap. Sunglasses help with glare off the water, especially in summer.
Why We Keep Coming Back
The Lock Keeper Trail isn't famous or Instagram-famous. It won't take your breath away with mountain views or coastal drama. What it does is offer something quieter — a chance to cycle at your own pace, see working history, and enjoy the kind of landscape that makes you want to breathe slowly.
It's a route that suits senior cyclists because it's flat, it's gentle, and it rewards you with interesting things to see along the way. The lock systems are genuinely fascinating if you take time to stop and look. The small villages feel real, not touristy. And you'll finish the day tired but satisfied — the kind of tiredness that comes from a good day out, not from struggling.
If you've done this route, you'll know what we mean. If you haven't yet, give it a try. Bring someone you like talking to, stop at Ballynacargy for tea, and take the time to watch the water pass by. That's what this trail is about.
Before You Ride
Choose activities that match your fitness level. Check local conditions and weather before travelling. If you have any health concerns — joint pain, heart conditions, or anything else — speak with your GP before starting a new activity. This route is designed for beginner cyclists, but every person's fitness is different. Go at your own pace, take breaks whenever you need them, and don't push through pain.
