There are 16 daedric quests, 8 divine quests. You could do those? thats what I've been doing. I may do the civil war with this character and then start a new one.
I'm in a similar situation level 48 now, have done the thieves guild quest line, working on the civil war now and yeah lot's of places not yet discovered... Part because I do use fast travel a lot and I have started to use it less, but also because I get sidetracked too easy. A cave to explore, a side quest to do etc etc.
Content in this game is plentiful, exploring also is quite rewarding. Have had several places I entered where I was given a quest inside it and that was by pure exploring, found locations that made me wonder what happened there etc. There is things to see treasures to find if people actually go out and look for it, some are clues you can pick up from npc's, others are more or less found by random.
