The dismantled railway line between Hartley and Stenkrith Park on the outskirts of the town, provides a level traffic-route for bikes, buggies and wheel chairs across to viaducts, thanks to the work of the Northern Viaduct Trust Ltd, find out more from their website.
Although not traffic-free, the lakeshore road between Pooley Bridge and Howtown offers a reasonably easy ride. It's 8 miles (13km) there and back, with the option of catching the Ullswater 'Steamer' between the piers at Howtown and Pooley Bridge for one of the legs.
The road is narrow in places and can be busy with other users, so better suited to families with older children.
There are two car parks in Pooley Bridge.
