Stew,not sure how experienced you are or how old your nephew is,so you could try Blyth harbour or Blyth Pier for starters,easy to find as well,just head to Blyth town centre either ask someone or find The Boathouse pub or Steamboat pub and its directly behind them (next to cop shop) the pier is found by heading north from Seaton Sluice when you hit the roundabout coming into Blyth take the third exit towards the sea front you\'ll see a caravan compound on your right you will have to turn rioght after the caravan yard and park your car on your right in the car park you\'ll be able to see the pier from here,you can also try Amble harbour its very save and again easy to find,Amble is quite a small Fishing Town so just head for the directions for the harbour
