Although with some the footpaths tend to go round them rather than through them, there are a number that you can explore. Suffolk Wildlife Trust reserves include Arger Fen and Spouses Vale near Assington, Groton Woods at Groton and Bradfield Woods at Bradfield St George. All are worth a visit and each has its own character. Other woods that are close by include Clay Hill Woodland at Great Henny, Loshes Woodland at Loshes Meadow, both an easy walk, and Assington Thicks at Assington and Marks Hall Estate a little futher away.
Last week I went on a 'Walk and Draw' with the Colchester Ramblers to Hillhouse Wood, West Bergholt, which is maintained by the Woodland Trust who have a wood finder website Visitwoods. They also have Fordham Hall Estate Wood and Primrose Wood near Boxford. The Ramblers welcome people joining them on their walks and their programmes are easily found on their website. Locally there are three Ramblers groups - Sudbury, Colchester and the Stour Walking Group, the latter for people in their 20's-30's.
Hillhouse Wood is interesting with undulating woodland and a rich variety of flora and fauna. The wood was carpeted with bluebells and swathes of wild garlic or rampons with their lush garlicky smell. There were also a few beautifully deep magenta spotted orchids which were quite a treat to see. I was also amazed at the trees flowering - both oak and hornbeam with masses of blossom as the leaves were just starting to form
