Visiting Mersehead with my RSPB Group

On Saturday 22nd November I am visiting Mersehead by Coach with the Newcastle Upon Tyne RSPB Group starting off by visiting a National Trust for Scotland property called Threave in the morning and then the RSPB reserve Mersehead in the afternoon. My question is what are the facilities like at Mersehead such as a visitor centre and bird hides. If you can help I will be most grateful.

Regards,

Ian.
