Furthest a Person Could Walk from Land

Disregarding water temperature, where could a person of average height walk furthest away from land? Lake, river, ocean, sea, whatever.

Does floating ice count as land?

You can walk out to Neuwerk, halfway being about 4 km from either shore. There may be places where you can walk out further into the tidal area, but it would of course be foolish to experiment.

The ocean waters off the coast of Maputo remain ridiculously shallow for a long time - sorry I don’t have a citation on just how far out.

There is a story, no doubt apocryphal, about someone who wanted to commit suicide by walking into the ocean in Maputo Bay. So, they tragically set forth, and walked determinedly into the sea. And walked. And walked. But even after a tiresomely long trudge, the still had not reached a point where the waters were too deep to stand. So they eventually gave up and walked back to shore.

You could reach parts of the Severn under ideal conditions, but there is dangerous sinking mud and very fast tides…

In the “Baie du Mont-St-Michel”, the sea withdraw as far as 15 kilometers (9 miles) from the coast during the lowest tides. The seafloor is rather flat, and that’s also the place with the highest tides in western Europe (up to 15 meters/50 feet). Assuming that the seafloor keeps being flat, I assume that someone could walk even further away than 15 kilometers, but I wouldn’t know how much.

Of course, venturing in the bay at low tide is considered highly dangerous.

I read in some guide that the flood tide off St.-Michel Bay can outrun a horse.

To be deep enough to paddle a canoe, you have to follow the tide about 10 km off Netetishi Point of the southern end of the Canadian Arctic Ocean’s Hudson’s Bay. It is a firm, flat bottom, so walking along in the water following the tide is easy (but it is one of those “you can’t get there from here” places, so very few people ever have the opportunity).
From my article:

Fun question.

Adam’s Bridge, between India and Sri Lanka ?

You are going to have to decide which of the numerous lumps of sand and coral are going to be considered land, and which are going to be considered sea… If we go off land as being above the highest of high tides…
then its all sea. Its 58km long

Somewhere in the Sea of Azov? The Arabat Split is significantly longer than Adam’s Bridge.

How reliable is Google Earth’s “elevation” data for areas like Adam’s Bridge? I would imagine it can’t be very reliable in an extremely shallow area like that. I was able to trace a path along the bridge without ever hitting a depth of greater than two feet, but I suspect that data is not reliable.

(Also, thinking about this question is really creeping me out. Having grown up in the desert, I’m always suspicious that the ocean is trying to sneak up on me and kill me. Walking way out into it seems like something that belongs in a horror movie to me.)

That’s a wise approach if you are wading (or in my case, paddling) at low tide miles from the high water mark, for the tide does sneak up on you, and if the wind sneaks up at the same time, you can be pummeled by breaking waves in shallows that are still far from dry land.

Another area with shallow waters is amongst the Isles of Scilly off Cornwall.

Lots of shallow land between them. I can find references to going 500m+ between islands at very low tide. But nothing about going farther by wading. The problem with wet walking is the currents in the area are notoriously nasty.

Between mainland Alabama and Dauphin Island (just outside Mobile Bay), there are several places where you can walk into the ocean more than a mile from shore at low tide and the water never gets deeper than your knees. I’ve been there.

I grew up nearMorecambe, in England; the neighbouring bay that shares its name can be walked across at low tide, if you know where to go. My school did the walk a few times as a fundraiser (the local lifeboat charity does most years as well, which pleases me), though I never did it myself.

According to this article about the one remaining qualified guide, in another section of the bay the tide could go out 6 or 7 miles, and local fishermen used to take horses and carts out instead of boats.

When the tide is in, I believe the path would still be under human height, but there are very strong currents, so it’s definitely not actually possible to walk it when the tide is in (drownings are not a rare occurrence).

It’s very often stated, but AFAIK, it’s a legend. Out of my head (I could be wrong), water rises on average at about 5 km/h, at the speed of a steady walking pace, which is already very quick.
