Coastal/tidal areas clearly need real respect.
That's very true of where I live, less than an hour's walk from the tidal channels and quicksands of Morecambe Bay.
I also live at the start of the Cumbria Way, which is essentially a lowland route, despite the two short forays it makes into the fells. The start point is in a town, and that's the first place where people go wrong. When they walk past my house, it's an instant FAIL, because the Cumbria Way starts on the next street to me. I'm currently working on a Cumbria Way guidebook, so I'm on a state of high alert when I see people leaving town in that direction. This morning, three guys set off, followed by a couple, followed by a foursome. I tagged on behind as an observer. The three guys overshot the very first stile and went marching up a road completely oblivious to what they'd done. I can't say I'd be too hopeful for the rest of their trek!
A couple of days ago, on the other hand, as I was following the Cumbria Way home, I came across a family crossing a field, around 3.30pm. Clearly, they were walking the Cumbria Way, judging by their packs, but surely they weren't intending to reach Coniston, some six hours ahead? Nope, it turned out they knew exactly what they were doing, and they'd studied their maps, and despite never having been in the area before, they told me where they'd be wild-camping that night. Some folks get it right!
