1 From Thatcham Station make for the Kennet and Avon Canal, a few paces to the south of the barrier, and turn right, signposted 'Ham Bridge'. Pass Monkey Marsh Lock and at the swing bridge, by a bridleway sign, turn left to Chamberhouse Farm. Pass between the sprawling farm outbuildings and follow the drive past the farmhouse and several cottages. The density of the buildings somehow conveys the impression that you are walking along the main street of a small village.
2 Cross the River Kennet and just beyond it the drive curves left. Keep right here and follow the track as it runs up through woodland to the road. Cross over to a gate leading on to Crookham Common and turn right. Follow the path parallel to the road, heading west. The television mast at Hannington and the ridge of Watership Down define the horizon.
3 Follow the former taxiway, now a popular walk, and pass a hewn log at the side of the path, carved and sculpted to provide three welcome seats. On reaching the disused control tower, branch off to the right and pass a gate on the left, leading into the main car park. Follow the path towards a cattle grid on the road, veering left as you approach it towards some trees and bushes. Look for a gate in the fence, cross the road to a track and head down through the trees into Bowdown Woods, a nature reserve.
4 Pass Bowdown Farm and the fairways of Newbury and Crookham Golf Course. Beyond the greens the chutes and conveyor belts of Lower Farm Quarry loom into view. A bird hide can also be seen here. Continue on the lane to a stile and gate and keep ahead, passing alongside the buildings of Lower Farm. Newbury Racecourse adjoins the route now, its striking grandstand can be seen in the distance. Pass under the railway and look for a swing bridge on the right, crossing the Kennet and Avon Canal. Once across, turn left and follow the tow path as far as Ham Bridge.
5 Cross over and follow the path along the south bank of the Kennet and Avon, making for Ham Lock at the confluence of the Kennet and the River Lambourn. Continue on a leafy stretch of tow path and cross over at the next footbridge, within sight of the White House pub. Keep to the path and cross the next bridge at the entrance to the marina. Pass Greenham Lock and walk ahead to the ring road. Pass under the road and alongside Victoria Park before reaching the next bridge. Leave the tow path, cross the canal into the wharf and keep right towards the tourist information centre and the Market Place. Bear left and head south, following Cheap Street to its right-hand bend. Continue ahead and then go round to the right for the railway station and a train back to Thatcham.
