All in all, "Eldorado" is a pretty easy read. Sure, there are a few historical words that need to be explained, like "bedight" and "Eldorado," but that's to be expected in a poem that's over 150 years old! The sentences aren't super-long or complicated (we're looking at you, John Milton!), and even if sometimes they start out a bit confusing, they end up being much simpler than they seem at first. In general, "Eldorado" shouldn't cause you too much trouble. If it does, just blame it on the dazzling vision of Eldorado that's in your head.
