I’ve cycled both up and down this trail several times now. As time as gone on, the track has expanded to the point where it is now possible to cycle from Plym Bridge all the way to Tavistock with only around 500m on actual road.
Starting down at Plym Bridge this trail follows the line of the old Tavistock railway and weaves it’s way through tunnels and over viaducts through some quite stunning scenery; the majority of it through woods and fields
The surface of the track is a rough finish (rough tarmac rather than dirt track), not really suited to road bikes, however I have ridden it several times on my road bike without any problems. Riding up from Plymbridge is a very slight incline but nothing you really notice until you are on a long straight and you can see it rise into the distance.
A mile up from Plym Bridge is a viaduct with an info board about to the Peregrine falcon pair that have been found to be nesting in an old quarry near by. I believe with a pair of binoculars you are able to see them during the spring / summer.
This track is great for a family day out on the bikes or even just for a walk however you do need to be aware of dog walkers and dogs appearing from nowhere!
