The Withey Beds Local Nature Reserve is open every day of the year. Access is via the main entrance on Moor Lane.
A typical visit will take 30-60 minutes. Part of the site has an accessible boardwalk, but other areas may not be easily accessible, particularly in wetter weather.
The Withey Beds is located close to Rickmansworth and Moor Park, with its main entrance on Moor Lane (A4145). There is no dedicated parking for the reserve, but it is often possible to park on Moor Lane in the layby opposite to the entrance. The Withey Beds reserve is a 15-20 minute walk from Moor Park tube station.
