While I think that's true of a lot of books, with Tolkien, one of the main reasons he is so beloved is the quality of the prose. The downside of this is that a lot of the writing is spent in description, or in retelling old legends, and other pieces of fluff that do not advance the narrative or tell us much about the characters we're following. I do believe that if you were to skip over this because you find it boring, you would be missing out on a large part of why Tolkien is special.

If you're skipping pages in Fellowship, you're not making it through the Frodo and Sam chapters in The Two Towers. I love Tolkien but I completely understand that he is a very difficult read. But if you want to actually enjoy and get through the trilogy you are going to have to read it slowly and take in all the prose, which is where Tolkien shines. My advice to you, if you feel you have to skip through sections, is to put the book down and don't waste your time on something you won't enjoy. Or alternatively read The Hobbit first (if you haven't already; it's not clear in the post if you have) which is far more accessible and a much tighter narrative. Then return to Lord of the Rings.
