Matthew, as Bob has mentioned all the information you require is available on the website, here is the direct link for you www.rspb.org.uk/.../index.aspx. There is a map of the site available to download as well. Unfortunately we do not provide binoculars at Old Hall.
Hope you enjoy your visit here.
as mentioned in previous replies - you will find answers to most of your questions (including habitat descriptions/opening times/contact details etc.) by following the links to our reserve on the main RSPB website. If you require any further information - please contact the reserve staff on 01621 869015 or by email to firstname.lastname@example.org. and we will endevour to provide the information you need. May I suggest that you time your visit to coincide with high tides, as this will enhance your enjoyment of the species we have by allowing closer viewing opportunities. Again, please contact us if you require information on tides.
We look forward to your visit.
