The Marin Trail — or as it’s now officially called, Gwydir Mawr a Bach —- is the mountain bike trail of all mountain bike trails.
We’re talking big climbs, bigger descents and breathtaking views of Snowdonia that make this trail a must-do in North Wales.
Here’s a complete guide to the Gwydir Mawr a Bach.
How Long is Gwydir Mawr a Bach/the Marin Trail?
The trail is around 15.5 miles, or 25 kilometres and reaches heights of 450m.
It’s easily accessible from the town of Llanrwst, just across the River Conwy, and its many winding paths provide plenty of options. This route starts from the car park at the trail’s northern entrance, gradually ascending as you walk south, then looping around to walk along the serene shores of Llyn y Parc before returning northward through the woods.
How Difficult Is It to Cycle?
Gwydir Mawr a Bach is difficult to cycle for novices, there are no two ways about it. It’s a red category trail (meaning difficult) and it will suit proficient mountain bikers with good off-road riding skills. Parts of the ride can be steep and tough, mostly single track with technical sections — not for the faint-hearted.
Gwydir Bach may be an alternative for those looking for a shorter ride. At 8.7km Gwydir Mawr’s little sister is less of a mammoth ride.
Can You Walk Gwydir Mawr a Bach/the Marin Trail?
Yes, there are plenty of great sections for walking.
However, you need to be aware of bikers using the main trail — if bringing a dog along, leads are a must. To avoid getting roped into a 25km walk (which would take a fair amount of time), we suggest just doing part of the route.
If you set off from the car park through a gate at the end of the road, you’ll see the main track leads straight ahead. Ignore this, and follow the footpath that branches off to the right. This will wind through the forest, giving you the best of both worlds: all of the wonder of Gwydir Mawr a Bach, without the panic of disrupting those on bikes.
Is There a Marin Trail Map?
Yes, there is a Marin Trail map. You can find the Gwydir Mawr & Gwydir Bach Mountain Bike Trail guide via visitconwy.org.uk.
