Suffolk Tip - New Wildlife Reserve
There's a lovely new wildlife area along the banks of Martlesham Creek, recently bought by Suffolk Wildlife Trust for rewilding. The land has been sustainably managed by an organic farmer for decades until he retired and sold the land to SWT, so it is already full of birds, wildflowers, butterflies, stag beetles, and other wildlife.
Park by Martlesham Creek church (Google Maps pin at 52.074492737355925, 1.298411890374119) and take the circular walk along the banks of the creek to the entrance from the River Deben, turn right along the seawall, then at the gate take the path straight uphill back to the car park.
