[Tagging] Trailhead tagging

Thanks for the comments. Please understand that the mentioned proposal is
not my proposal.

We just kept the idea of a trailhead node marking a place specifically and
visibly designated to start one or more hiking routes, bicycle routes,
canoe routes, horseriding routes.  Just a crossing or the starting arrow
of a single route has no need for this kind of tagging. Just a map or a
board, not a trailhead. Just a parking, not a trailhead.

In the US many trailheads have been mapped because they are places where
you are allowed to access a single trail. The may not even have a name
other than "Start of <trail name>" and a location name, but the are listed
and offered as designated trailheads.

These simple trailheads as they have been tagged consist of a node tagged
highway=trailhead and usually the name, and someties additional tags. The
node may be standalone or may be the first node of the trail or of a
branch. The node if standalone may coincide with a board or map or
guidepost.

So my suggestion is exactly that: use a node marked as trailhead,
preferably with a name it can be extracted, listed and rendered as being a
designated trailhead.

In Nederland we use some further tagging to indicate the modalities and the
facilities. The trailheads are specifically designated and designed for
transit to routes of all kinds: bicycle en walking routes, roundtrips and
networks are standard, free parking space must be available, a special
landmark marks them, and there are always some benches; a restaurant or
cafe nearby.

To see the trails starting at one of these places you best look at
Nederland on waymarkedtrails. They all have multiple hiking/foot routes and
walking routes to hop on, and most support other modalities.
Pity that the trailheads themselves are not yet rendered and clickable on
waymarkedtrails, but we are working on that.

So tagging becomes more complicated, but the basic function is still the
same: search, list and render places specifically designed to get out of
the car and start walking, cycling etcetera.
The node in this use case will always be standalone because of the
multimodality and many routes that it serves.

About the use of referencing tags. I agree this is not yet the best result.
Wikipedia links to the dutch page for TOP's (as they are called here), I
think that is correct. url links to a site which lists all the official
dutch trailheads. website links to the recreational publishing sites of
different official operators. Each province has its own operator (and
trailhead style).  Some of those have a web page for each trailhead, others
have a simple list, others an interactive map or search function... and
they reorganise quite often. Permalinks? What? Never heard of...) so we
don't link deep but refer to a list/search/map/filter page.

I'm sure the coming years will show what keeps and what not.
