Horse riders, mountain bikers and walkers are helping celebrate the official opening of a scenic 17-mile link to the Pennine Bridleway National Trail at St Ives Estate, near Bingley, tomorrow.

The official opening of the new Calder Aire link route was being marked with a walk, cycle and horse ride along part of the route.

The Calder Aire link runs from St Ives to the Pennine Bridleway National Trail at Widdop Road, near Hebden Bridge, through a variety of landscapes including woodland, moorland, sheep pasture and ancient lanes.

It is hilly in places offering panoramic views. The trail is mainly off-road on a mixture of surfaces including grass, bare earth, crushed stone, grassed-over tracks, stone pitching and some tarmac lanes.

A total of 120 miles of the National Trail are already open from Derbyshire to the Mary Towneley Loop through Lancashire, Rochdale and Calderdale plus the ten-mile Settle Loop in the Yorkshire Dales.
