Not sure what you like to shoot, but Kessingland wild life park is fairly close. Minsmere is probably 20 miles away if you are into birds. I took a nice landscape from one of the hides with sizewll B lit up in the distance.
If you have kids take them to Pleasurewood Hills and/or Yarmouth Pleasure beach, but don't take yer kit.
Never been to Somerleyton Hall, but may be worth looking that up,as it's close by.
