I suggest you contact the RSPB directly about this. Frampton is a striking reserve, but on my sole visit I noted the lack of places to park one’s weary wotteva- and assumed, since it was then newly open, that this would soon be rectified. Obviously not.
Have done numerous times and at other nature reserves. What impressed me about Titchwell was that they were provided as a matter of course. For some seats are not a luxury but a necessity!
Yes I know lots of places dont make provision and I often go to such places.
However seats make life much more bearable for us crinklies and again I congatulate those involved at Titchwell.
