We are visiting 1 June and staying in Berwick-Upon-Tweed the night before. Crossing looks like it's allowed at 08:35 and we were hoping to get there early and walk around the island. This seems like a silly question as a "walk around the island" seems pretty descriptive. Is the trail self-explanatory? Is there a defined trailhead? We are also planning on booking a walk with Mary later in the day. Any thoughts on this or other ways to spend time until the visitor center opens?
Thanks in advance for your insights.
