Meet at 10.00 am at the car park in the Aquadrome. The Aquadrome car park is at the top of Frogmoor Lane in Rickmansworth. We will be walking along the Ebury Way, a disused railway line, until we reach Croxley Common Moor, a nature reserve. We will then walk across the moor, join the Grand Union Canal, and return to the Aquadrome for coffee. A total of about 4.5 miles on uneven ground, but no hills !
