(3) Base Camp
The language is relatively easy (aside from the occasional unfamiliar fruit or animal), and the basic story of the poem isn't too hard to get our heads around. But you could spend your whole life trying to unravel all the possible layers of metaphor and allegory. (Trust us, people have done just this.) This tension is one of the reasons this poem is still so popular today – it's great for beginning readers, but it's still got a lot to offer more experienced readers, too.
