Hi Florall, It's a great reserve with helpful staff at the information centre (I think there is an RSPB office here as when I asked a question about Red Kites in Oxford, a long way from Lancs, they ran off and found "somebody who would know").
Given our previous chats it may be worth giving them a call about access/distance to the hides. The "Public Hide", where I saw my first Bitten last December, is over a 1000 metres from the information centre, but there is a road/track to it that may be able to be used if given permission. On the December day I visited I chatted to a local birder who reported 27 species easily viewable from the "Eric Morecambe Hide" (but I had to go back to the family so can't give you a list or details on accessability).
Regards,
Paul
