Dunwich Heath - a National Trust property adjacent to Minsmere RSPB reserve.  Wander through the heather - spectacular in August - visit the Coastguards' cottages for sea views, a meal, and the NT shop.
Foxborrow Farm - a Suffolk Wildlife Trust site. "A wander along the farm trails gives visitors a chance to see some of the work done by the Trust and our tenant farmers to improve the site's wildlife interest."

RSPB Reserve at Minsmere - famous for Avocet, Little Tern, Bittern, Marsh Harrier and many others.  Excellent visitor centre.
RSPB Reserve on Havergate Island - wilderness on a shingle island, a stone's throw from Orford.
Rendlesham Forest - now recovered from the Great Storms of 1987 and 1989.  Picnic areas, cycle ways and waymarked walks. The deer, above, were photographed in Rendlesham Forest.
Daisy's Walk is a particularly delightful short walk near to Rendlesham Forest.
The whole area is helped by the Suffolk Heaths and Coasts Project - "working to increase the awareness of local people and visitors about what they can do to look after the Suffolk Coast and Heaths"
