There are plenty of tutorials available. For example:

But it might be better if you describe what assets you are using, what problem you are having, and what you regard as 'realistic'.

Try to avoid using "Big Block Head" "Snap To Grid" tunnels

Use 1x1 digholes, and center the track on them

Adjust tracks so that they are aproximatly in the center of the bottom plane of the dighole 1x1

Adjust the Tunnel Portal just so that it covers up the bottom, outrmost plane of the dighole

You will have to tug up/down (using radius set at minimum) on the the 2 upper corners of the dighole 1x1 plane, so that it just touches the top portion of the Tunnel Portal

Placing Twees and Gwass you will cover up a multitude of sins

I wouldn't use any of those methods.

Keep in mind, some tunnels just do not work right.

Here's the way I do it:
