We stayed here a few years ago and loved it! It would suit us even more now for size until we have 'the vaccine', with about 48 pitches for adult only spread over 2 fields with ample space. We had a grass pitch in the second meadow with views across the fields to the coastguard cottages on Shingle Street. There is the pond and being in an edge-of-village location you can enjoy other wildlife, we heard but not saw, owls hooting locally..
We approached from the A14, crossing the river Irwell then taking the A12 to Woodbridge, then B1083, Heath Road towards the site. Don't be tempted to drive through Ipswich which does save about 6 miles and might come up on SatNav! We have only tried Cambridge services once, drove in and out without being able to park, so for my book worth seeking an alternative stop!
Sutton Hoo is absolutely worth a visit and paying a few quid extra for a guided tour of the site to fully grasp the history (NT).

Also Aldburgh and Southwold a tad further up the coast.
