There's no doubt in my mind that the best holes are to be found at Brancepeth. That said, it isn't links and could be wet in March and it's a good 90 minutes from Goswick. Bamburgh is absolutely beautiful. On a sunny day it's up there with CPC and NSW and I am not exaggerating. That said, it isn't, for the most part, great golf, though it's decent fun. I don't like Foxton. Dunstanburgh is fun but it's a while since I've been there. Seahouses isn't worth a stop.
I haven't played Warkworth or Alnmouth Village. If you could get a deal at Scott MacPherson's Close House Colt it's well worth a visit. If you're up and have a space in your crew, let me know.
