1 From the back of the car park follow the old Cromford and High Peak Railway trackbed eastwards across lofty fields. The track swings south after passing over the first of two huge stone embankments. The railway track goes through a cutting where cowslips and orchids grow, then past an old stone quarry with a rusting crane tucked in the shade of the rockface. Back onto another railway embankment above Minninglow Grange Farm, you'll soon notice a complex of Victorian brick kilns. High-firing silica sands found near the farm were made into bricks here, for use as liners for the steel furnaces of Sheffield.
2 On reaching the brick kilns, leave the railway trackbed behind and turn left along a track known as Gallowlow Lane. This follows the original boundary of the medieval grange estate and is assumed to have been of medieval, or even of Roman origin. To the left is Minninglow Hill. The crown of gaunt beech trees hides an ancient barrow, Minning Low. This was excavated in 1851 revealing a very large megalithic chamber and several imperfect cists (stone coffins). One, however, was intact and with its capstone in place.
3 After about ¼ mile (400m) climb the stile in the right-hand wall, and follow the path under the old railway tunnel. Take the right of two gates in the next crosswall, then continue down a grassy hollow. Eventually a wall comes in from the left and the path runs alongside it. While you're here, look southwards and you should see a Bronze Age barrow on the next hilltop.
4 Go over a stile in the wall, then continue along its left side. Beyond another stile in the next crosswall, bear slightly to the left across a field, aiming for the top left-hand corner and in the direction of a building that looks like an old chapel. A stile here gives access to a farm track from Roystone Grange. Turn left here for a short way, before going through the waymarked gate towards the 'chapel'. The building is in fact a pump house whose engine used to send pressurised air to power the pneumatic drills used in the quarries that you saw earlier.
5 Follow the farm track north, past the modern farm to the disused dairy. The excavations here in 1978/9 unearthed the foundations of an old Roman manor, which stood on the boulder-strewn terrace beyond. The 2nd-century building would have had rubble-built walls and a thatched roof supported by aisle posts.Turn left along Minninglow Lane which takes you out onto the road proper, leading northwards back to the car park.
