A link from the NCN to the Creswell Crages and Harley Gallery visitor centres. Use this as part of the Grand Tour.
You can follow NCR6 from Sheffield via Rother Valley Country Park. At Harthill, look out for a right turn onto Serlby Lane. A short but steep climb ensues and will take you out to open countryside and past a wind farm. Take a right onto Bondgar Lane (careful on the curves here) past the golf club and turn right on the A619 with care, with an immediate right onto the B6043 which will take you down to Whitwell (Railway Station on the Robin Hood line, Nottingham – Worksop. No Sunday service) . Turn r. onto Scotland St – Southfields Lane – Crags Rd. This will take you past Creswell Crags which is another local attraction. (The map shows some alternatives) Follow through to the A60, turn right with care and Welbeck Garden Centre, the Farm Shop and the Harley Gallery are about 100 yards along on the left.
The Nottinghamshire Grand Tour is “The Grand Tour is the formative cultural experience of the 18th century traveler – made modern day. It invites you to view the treasures of Nottinghamshire and Derbyshire through the eyes of today’s leading artists”
The next stop on the Grand Tour is the Contemporary in Nottingham. You could do both in a day, probably making use of the train, but note that on Sundays the Robin Hood line only goes as far as Mansfield Woodhouse. The tour continues to Chatsworth and the Derby Museums – it would be pushing it to do the whole thing by bike in one day but it would make a great weekend.
