From Cambridge, take the A10 towards Royston. Go over the Foxton rail crossing and in one mile reach the Fowlmere-Shepreth crossroads. Turn left towards Fowlmere. After one mile, turn right by the cemetery. Follow minor road for just under half a mile and at the RSPB sign turn left onto small road into the RSPB Fowlmere Nature Reserve (watch out for two barely visible speed humps!). Nearest postcode: SG8 6EZ.

Park at far end of the Nature Reserve car park. There is a £2 per car parking charge for non-RSPB members (members need to display membership card in their car windscreen), payable by phone or cash in a ‘Donations’ black post box by the entrance hut.

The walk starts at 10.00 am. It is a virtual figure-of eight. The first loop, of 3.6 miles, is RSPB Fowlmere-Fowlmere Airfield-Fowlmere village (including the Round Moat)-RSPB Fowlmere. The second loop is a circuit of the nature reserve, which is free entry, to make a total walk of 5 miles. One gentle incline early in the walk but otherwise basically flat, good tracks and paths, no stiles.

To book a place on the walk, please text/leave voicemail message on 07716 992847 or email (phillipjhastings@gmail.com) by 6.00 pm on Saturday April 22.
