Our family with sons aged.16 and 12 all loved this experience. The staff at Blackwell Mill were incredibly welcoming and friendly and could not have helped more. We hired two adult bikes as the boys had brought their own but they were happy to pump up the boys tyres and lend us extra locks at no extra cost. The advice given was perfect (especially about the slight uphill return!) and we enjoyed the stunning scenery all the way to Bakewell and back. The tunnels are awesome! An experience not to miss.
