Day 10: We were up early again this morning, ready to walk the city walls of Berwick-Upon-Tweed. We stayed on the other side of the bridges at Tweedmouth, on a site overlooking the Spitall. So we crossed the 'old bridge' to Berwick and started our walk around the city walls. Whilst walking to the lighthouse we saw a grey seal bobbing about and swimming in the River Tweed! We could also just make out Holy Island/Bamburgh Castle through the mist from this side. The Elizabethan Ramparts and Berwick Barracks are really well kept/looked after. After a lunchtime meal in a hotel (one of only 2 in the whole city that were doggie friendly!!) we did the riverside walk under the viaduct to the ruins of Berwick Castle. In the evening we walked along the Spitall Promenade.
