I want to create something like the first row of pictures here:
https://www.google.com/search?q=povray+cave&espv=2&biw=1838&bih=995&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjk6-TN7fPKAhVW22MKHTxUCdgQ_AUIBigB#tbm=isch&q=cave+entrance+model
It can be an entirely natural formation and not man-made.
What would be a good way to go about doing it?
Mike

I did a tunnel with a heightfield and a bore difference.

For the organic-looking cave itself, I would use the HF_Cylinder macro in
"shapes.inc". (See my recent post in Sven's "CLipka: Possible BUG Found!!!"
entry for an example of how to use that macro.) Then maybe another 'regular
heightfield for the face of the cave (standing vertically.) Joining that
combination to the ground-- so that it all looks like 'one thing'-- may not be
so easy; maybe by submerging the HF cylinder into the ground a little (which
would be yet another heightfield), along with some extra rocks around the
join-line to 'hide' it.
Or you could model the entire cave in a separate mesh modeler and import it into
POV-Ray ;-) I still use a *really* old and simple app called sPatch for
building things like that.

The important feature is the *mouth* of the cave, not the interior.

I doubt a heightfield will do the job. Plus there's the matter of
creating the heightfield itself. Maybe a stack of isosurface objects
made to look like boulders or strata of rock?

This is really the best solution I can think of. Unfortunately I am not
much of an artist unless the scene I'm modeling is mostly geometric.

Something like this maybe:
http://www.turbosquid.com/3d-models/3dsmax-stone-arch/947583
Or even as simple as this:

I'm not sure what you're asking. You want to make granite blocks?
Anyway, here's mine.

I just meant that heightfields are great for large scale scenes, as
would carving a tunnel.
A cave mouth wouldn't need to be very large.
