it was there a minute ago verses !
Glad I copied and pasted it to notepad beforehand, it took me ages to write!
Let me try again
Coast:
Southwold, Aldeburgh, Minsmere (RSPB reserve), Shingle Street (remote and rumoured German WWII landing site), Bawdsey (Radar development site), Orford (Castle) and Orford Ness (Nature reserve and former military testing site), Felixstowe (“Old” and “New” ends, old is quieter with a small ferry across to Bawdsey, new end is more of your typical “kiss-me-quick hat” type UK seaside town, although it does have the Landguard Fort – old sea defence site – and the cafe overlooks Felixstowe port – not sexy, but the size of some of the ships is worth a look)
In-land:
Lots of pretty and picturesque little towns and villages; Framlingham (Castle and some of Detectorists was filmed in the town. Oh and Ed Sheeran’s sometimes spotted there), Woodbridge (near Sutton Hoo – famed Saxon burial site), Lavenham (more thatched cottages than you can shake a stick at, including one used as exterior of Harry Potter’s parents house), Flatford (home of artist John Constable and scene of “The Haywain”).
If you were to go to Bury St Eds from the coast, the drive along the A1120 to Stowmarket then onto the B1115 via Rattlesden is quite picturesque.
As for Ipswich, I think flange has been a bit harsh – as with everywhere it’s got its nice bits and its bad bits, but there’s plenty of parks, a lot of history and a nice-but-unfinished waterfront development.
Biking:
Suffolk has a reputation for being flat, while there’s no major climbs, I think rolling is a fairer description, and there’s no end of quiet country lanes for road biking along. If you were bringing an MTB, there’s a nice bit of waymarked Singletrack in Tunstall Forest as well as plenty of off-piste, there’s also Thetford/Brandon and Dunwich forests.
