Sunday 19 September - Open access in the Peak District begins
BY INVITATION ONLY - The Peak District National Park Authority are hosting the national launch of the new rights to walk on wild land. The event is to be held at Derbyshire Bridge, Goyt Valley with the Rt Hon Alun Michael, Minister of State for Rural Affairs and invited guests.

The size and significance of the launch event will mean a temporary ban for cars in the vicinity over weekend of 18-19 September – but walkers will not lose out as a free park-and-ride scheme will be available. Derbyshire Bridge car park will be closed on September 18-19, and parts of Derbyshire Bridge Road and Goyt Lane will be closed on September 19, 10am to 6pm. On September 19 a courtesy bus service will run, 10.30am to 6pm, from Grin Low Country Park car park (Grin Low Road, off the A53 Buxton to Leek road) to Derbyshire Bridge, and motorists will still be able to use the nearby Street car park near Errwood reservoir.

We apologise for any inconvenience this may cause, but we would ask the public to bear with us for a short time while we make preparations and while the event takes place as this is a nationally important event.
