A system of intergalactic wormholes are, generally speaking, major arteries of intergalactic travel, being the fastest and most cost-efficient. However faster forms of FTL travel-- such as Hyperspace-- can potentially be used for such as well, though any journey would take a very long time; months, years, decades or centuries even. It depends on how sophisticated the Hyperdrives in question are.

Given that Hyperdrives are about the only form of FTL one can hope to use to travel intergalactically, this means that, aside from the use of wormholes, intergalactic travel within a single Human lifetime is a feat that can only be performed by roughly Tier threes and above. Always use the Tier system with a grain of salt though.

Hope this helps!
