Bell tents in Thetford Forest

From its confluence with the Great River Ouse, the River Lark winds southeast to Isleham, nine miles from Thetford Forest, before continuing upstream to Bury St Edmunds and beyond. Navigable until Jude’s Ferry between Isleham and Mildenhall, and with a major marina at Isleham, the waterway is a favourite among pleasure boaters and walkers who frequent the footpaths lining the river. Several campsites dot the area, some near the water.

The town of Thetford hugs the forest’s southeast corner, east of which are many important wildlife areas including Brettenham Heath National Nature Reserve with its nationally rare chalk grassland and heathland habitats, plus the SSSI Knettishall Heath Nature Reserve. The Peddars Way long-distance path runs east of landscaped 18th-century parkland Shadwell Park, then intersects with Icknield Way near Knettishall Heath. Look for a fair number of kid-friendly campsites nearby.

West of Thetford Forest, pancake-flat farmland spreads across to Ely. This is one of Britain’s smallest cities, arranged around a stunning cathedral on the highest land in all the East Anglian fens  (with a whopping elevation of 85 feet!). Ely’s countrified surroundings, also known as Bedford Level, are the place to come for excellent boating and a fine choice of campsites, many with pitches scattered through lovely wildflower meadows.
