Just got back from 5 days on Watts Bar Lake, just west of Knoxville. I live in NW Ohio and it was about a 7-hour trip each way. One word....WOW!!!! I've been to Cumberland and this place is much, much, much nicer. No houseboat rentals on the lake so it's not absurdly crowded.....actually on Wednesday and Thursday we probably didn't see 20 other boats. We stayed at a very, very nice house in a cove, right across from a marina with gas and a pretty cool little "local bar" in it, which we made good use of a couple nights. The lake was 91 degrees. Even out in the main lake, you could run for 10 minutes without passing another boat. Check out the house....it's at www.tlcvacations.com scroll down to Lakeside Lodge. If you're looking for a great week or even weekend trip, I'd recommend it.
