Just in case anyone is considering this, make sure you understand how tides work and are aware of the tide times before going anywhere near the sea here. A spring tide comes in faster than you can run.

It's worth experiencing the tide in a safer place like one of the North Norfolk beaches. At low tide the beaches are vast and mostly sand. Stay away from mud. If you walk right out as the tide is coming back in you'll find yourself walking backwards to avoid the incoming tide. You need to keep your wits about you to avoid wet feet. In particular make sure your path back to land is on high ground and isn't getting inundated behind you. People get cut off by the tide all the time, but it's usually because they've sat down somewhere out there.

Came here to post exactly that. Had a few friends walked this with a guide last summer as it's on their to-do list of trails.
