I'm a novice Trekkie, so the answer I'm looking for may be obvious to lots of people, but I have no idea. When traveling the wormhole, does one enter at Bajor, then exit at the Idran System, or are there ways to enter and exit the wormhole at other points along the way?
The wormhole is effectively "point-to-point". It connected a point in the Bajoran system (within the Denorios belt) to a point in space 4.7 lightyears from the Idran system in the Gamma Quadrant (DS9: Emissary). There is no evidence in the show that it is possible to enter from any other point.
It was possible to end up in different realities (DS9: Crossover), but this was under exceptional circumstances, and the locations in physical space were the same.
It was also possible to end up in different times (DS9: Accession) though this was through the direct intervention of the Prophets, so may or may not be a property of the Wormhole as explained by in-universe physics.
