I find the early and mid-game great fun: there's excitement and challenge as I explore the world, found cities, and challenge the other players. But then the end-game almost always turns into mind-numbing slog.
For example, right now I'm playing 8-player vs. AI. I've reached the point I always seem to reach: it's basically inevitable that I'll win now, but I still have to give repetitive orders to tens of cities for a hundred or more turns to wrap it up. I go in hoping for an interesting victory condition, but I usually fall back on Conquest since that ends the monotony a little quicker.
A friend of mine has the same experience. Are we doing something wrong, or do we just lack the needed patience? Are Civ end-games usually longer and less challenging than the openings?

Tedium comes from feelings that you're making a lot of decisions that don't really impact anything. So...
Minimize how many decisions you have to make:
(Of course, try to get rid of the decisions that don't matter, and keep the ones that do.)
From my experience, quick games on average are just more fun, because even if the game is bad, its over quickly. Then you start a new game and have a chance to learn from mistakes all the sooner!
