Please meet at 10.00 am in the car park at Cassiobury Park. The car park is at the top of Gade Avenue, off the A412 Rickmansworth Road. We will walk through the park and nature reserve and have coffee at the café. You can also join us from Watford Metropolitan Line Station, which is only a few minutes walk away. Turn left when leaving the station, and then right onto Gade Avenue, which leads to the car park.
