The next time you encounter a complicated web of route options, remember a site called Rome2Rio.
Rome2Rio shows every last possible travel option in a single streamlined place. It even finds routes Google Maps misses—that’s the main point.
This site is fantastic. As I recall, you can do a whole string of destinations and it finds every possible route. Great for getting around Europe when I was on a tight budget.
My 2 cents: it’s is great when travelling but I end up visiting the website of the bus/train company to actually book the ticket, so it’s mainly useful if you are somewhere and you don’t know the companies offering public transport.
Edit: I’m from Europe and never went outside of it, don’t know anything of how good it works in the rest of the world.
