It might be interesting to take cave-automata-2d and define a grid, say with 16 points, and assign heights at the points. You can then interpolate a spline between the points to create the vertical axis for the cave using 2d automata for the x,z axis. Essentially just combine a heightmap with the automata.

Some good discussion of terrain generation at https://news.ycombinator.com/item?id=7734925 http://www.playfuljs.com/realistic-terrain-in-130-lines/ (but this example is using midpoint displacement, 2d, not 3d simplex which would give rise to caves). https://www.npmjs.org/package/cave-automata-2d could also be worth looking into.
