I am going off the top of my head here...
Isn't there some kind of "shadow door" spell that basically does that? Kind of similar to "tree stride" or "fire stride".
I think that there are some magic items as well -- I am thinking specifically of "ring gates".
At least that is just off the top of my head.

Heathensson, since you're into the Nordic thing, you could have menhirs/stone circles have a similar transportation effect. Standing stones were covered in the Masters of the Wild splatbook, don't know if they got updated into Complete Divine, but they were a druid-oriented "spellholder" that you may find intriguing.
Nodes, from Forgotten Realms: Underdark might be worth looking at as well.
