Sorry to see that no one has answered you questions. I don't usually look at this forum and have been away.
Snape RSPB.
=========
Newish site and still being developed with reed bed reversion. Usually warblers around though may be getting a little late. Don't think they have have yet got the big three reed bed specials breeding - Marsh Harrier, Bearded Tit and bittern - yet, but they are expected in the next year or so.
Also go East from the Snape road towards Sailors path and through the woods. If the tide is middling (about -1.5 hours from Harwich port time) good for waders, and lots of avocets should be around now.
The Southern section can be walked by going south from the Maltings, taking the first left, then the second left, then left again down a track I think signed to "Iken Cliff" where there is a car park (free) popular with dog walkers. Turn right/east and walk along the river bank.
If the light is right the view back to Snape Maltings - the concert hall - can be beautiful.
The concert hall and its environs with
non-tacky shops (though expensive) is worth a walk around and a concert if one happens to be on and interests you. There is a lot that is not Benjamin Britten!
North Warren
==========
NORTH WARREN RSPB RESERVE - birdingsiteguide.com
Bit of a complicated area, with grassland (breading lapwings) to the West, marshes to the East (most easily viewed from the footpath on the old railway line, or the Aldeburgh beach north car park, and then Aldringham fen and woods. One of the houses just to the NW of the fenn has feeders out and usually has a good assortment of passerines.
In autumn and winter the marshes are heaving with wildfowl and geese; I guess some will have come by now, though there are a lot of resident greylags.
Aldeburgh
=======
As above, and south are the Aldeburgh marshes.
Aldeburgh (and Southwold) are unique really. Idyllic retirement on the sea for retired generals, admirals, medical consultants and those not quite nobility.
Its an interesting mish mash of architecture with tiny little fishermen's cottages and some larger victorian houses.
Drive to the South and go up on the sea wall and enjoy the view of the sea to the East and the river 200m to the West, that still has eleven miles to reach the open sea. BG gulls and turnstones usually do a good photo opportunity for payment of a few crumbs. Oh I forgot, there is a bye-law against this now as the Herring gulls have become a serious pest to those eating Fish and chips.
Oh and on the subject of fish and chips, it is OK for the nobs above to buy fish and chips from the town as it is allegedly the best anywhere and it is fashionable to be seen queuing 200 yards down the street.
(The second f'n'chips is owned by the same family).
Havergate Island and Orford Ness (?NT).
=============
Both need boat to get to from Orford. Breeding sites for Avocet and Gtr Blackback gulls. Not really the right time of the year. Orford is pretty though and walk down the river bank will give some waders unless high tide.
Boyton Marshes
============
I am sorry but not sure about where the reserve is, but I have walked the whole area! Good walk along the bank at edge of water - similar to Orford, and also Shingle Street.
Minsmere
=======
Winter migrants arriving but this is the quiet time of the year.
Likely to see visible migration.
The red deer rut starts mid-september. Better to ask when you come, but you do not see the rut from the reserve car park, rather the Westleton to Dunwich Road.
Hen Reed Bed
==========
Suffolk Wildlife trust, on the road from the A12 to Southwold.
Has bittern and Marsh Harrier but unlikely to see the former.
Some people just look out across the reeds from the viewing platform and don't cross the road and walk down the banks on the side of river Blythe with fresh water lagoon on the North side.
Dingle Marshes
===========
Just to the North of Dunwich Beach car park.
Blythburgh
========
Often good views of waders looking East from the A12, 300m North of the White Hart pub. Again tide dependent.
(never seen anything interesting over the alder scrub to the West!
Framlingham
=========
Where you are staying. Lovely old market town and castle worth a visit.
There is a mere at the bottom of the castle that can throw up herons and passerines. Quite pretty!
Woodbridge
========
River Bank walk
Park at (52.104001070944086, 1.3399028778076172)
between the railway crossing and the Wilford bridge pub. Either up or down stream.
The Tide Mill is currently closed for renovations, but it is pretty.
Languard Fort, Trimley Marshes and Levington Marina and ponds
===============================================
Head for Felixstowe.
All worth a visit and the web will have plenty of info.
Beware Trimley marshes as it is 2 mile walk to the reserve (but can be cycled).
Under the Orwell Bridge and A12
========================
Easy tidal are to watch. Not sure if the peregrine has been around recently or not, but look up under the Southern most of the central two supports for his nest box.
Further afield you have Redgrave and Lopham Fenn (Suffolk Wildlife Trust), Carlton Marshes, Benacre Broad etc..
Lackford Lakes
===========
Just West of Bury St Edmunds.
Lovely place; water and woodland and some fenn.
Lackenheath
=========
Quite close to Lackford.
Flatford Mill
========
Not especially good for birds, but it is heart-rendingly beautiful and where Constable painted many of his famous pictures, including the Haywain.
Mistley
=====
Getting South now, but close to flatford is the mudflats of the River Stour. Too many swans really (they are fed) but usually good waders. There is another RSPB reserved 5-10 miles down the Stour on the South Banks, but its name eludes me.
Fingringhoe and Abberton Water are not far off either
====================
Fingringhoe is my favourite
(Don't bother with Alton water unless you are desparate to see Greylags and Egyptians.)

Along with North Norfolk it is one of UK's greatest birding areas.
