There are five days remaining before a consultation ends on a proposal to create a trail along an old railway line between Coniston in the Lake District and Broughton-in-Furness.
Cumbria County Council and the national park authority want to establish the route - known as the Foxfield Trail - along the ten-mile track that will provide walkers, cyclists and horse riders with a new leisure facility.
The authority said that the gentle gradients involved would make the old line particularly suitable for youngsters, something that could encourage lovers of the outdoors to buy children's bikes for their kids.
Most of the old line lies inside the national park, running through the village of Torver en route.
Such a development would not be the first time a former railway has been turned into a linear trail in the Lake District.
The old line between Keswick and Penrith has been developed this way, although there have been campaigns for the rail link to be reintroduced.
