From the M1, St Peter's is closest to Junction 28. Exit eastbound onto the A38; at King's Mill Reservoir turn right onto Mansfield Road (still A38) until the T-junction with Portland St. Turn right, continue and take second left (first left after crossing over the railway tracks) onto St Peter's Way. First left from here will take you onto Commercial Street, with the entrance to the retail park clearly visible on your left.
St Peter's can be accessed directly from the wheelchair-friendly pedestrian ramp of the westbound platform of Mansfield train station. Mansfield station is served by half-hourly services from Nottingham to the south and (hourly) from Worksop (and Mansfield Woodhouse) to the north. For more information please visit National Rail.
St Peter's is about 4 minutes walk from Mansfield Bus Station, just to the north of the retail park. There are many services from Nottingham Bus Station, including the 'Pronto' service run by Stagecoach East Midlands.
