How to Visualize a Wormhole Somewhat Accurately?

So, as I've mentioned in previous questions, I am writing a series in which the four young main characters encounter natural, traversable wormholes that connect the present time to another one. I've vaguely figured how I want them to work and how this way connects (mostly) to the real theoretical science behind it (specifics will be explained below for those curious and if it connects to my question). My question now is this; If I want to continue being vaguely scientifically accurate, how would a speculative wormhole look to humans looking at it from outside? For someone stepping through it to the other side? How many artistic liberties can I really take while still being scientifically accurate? Thanks so much for taking the time to speculatively answer this question and have a good day!

(For those interested, the wormholes tend to stick near objects with larger gravity to keep our intrepid little explorers from stepping through one and ending up somewhere out in space and suffocating. They tend to occur most on the time equivalent of "fault lines" where time 'tears' more easily, like weak points on a blanket. Yes, I do know it's definitely more complicated than that, but I'm simplifying things a bit so it makes more sense. They also can connect places in both place and time, so they can end up from a little town in modern day Oklahoma to the volcanic jungles of Early Cretaceous China. Finally, they are also traversable by simply stepping through since the main characters are just a few teenagers who stumble across them and don't exactly have resources to get a vessel to take them through Interestellar style.)
