This is a really neat resort with lots to do. It is well kept and managed. Pool is just the right size and very clean. The namesake lake seems to be underused, but it apparently has lots of fish and they have boats available. If you bring a kayak you may be the only one out there and it is basically 5 minutes from end to end, but there are other areas in this region to paddle if thats your thing. This resort is a true hybrid, and entertains adults as well as kids. Kids get a pool party and crafts on Saturday. For adults, there is a margarita bar with regular 'bags' tourneys, and on some Saturday nights, a live band playing until around 10 PM. A large proportion of the park is seasonal, but the daily area gets the prime spots near the pool, store, and shower-house. Its not the quietest campground, but is a good mix, and gets much quieter after the band shuts down. Ask about the weekend's agenda, or seek a site farther from the pool to get some distance from the band/stage. We were here on a rainy weekend and the band started about an hour late, so it ran until after 10:30, when the agenda said it would end at 9:30. Not a big deal, understandable I guess. Nearby is Timber Lake Playhouse, a summer stock professional theater that is surprisingly good for such a rural area. We saw Joseph and the Amazing Technicolor Dreamcoat. If you are here during the theater season, see what they are showing, they are really quite good. Timber Lake is a one of a kind resort with something for everyone, as long as you don't want to go to sleep too terribly early.
This park is well maintained and in high demand. Please note that there are reservable sites for 3 loops at recreation.gov, and these are often full most weekends. There is one remaining loop, arguably the best one (has boat launch, great sunset views, and one of the only two bathhouses) that is first come first served only. Many locals come out on Thursday and very early Friday to snag a prime site in this loop. Grand Illinois Bike Trail is adjacent for nice rides to Fulton or Savanna. Nearby Thomson has a neat cafe with regular live music, the Heirloom Market/Cafe. Thomson also has a fun estate auction house; look up Tipton Auction Service for the schedule. Halfway to Fulton on the highway is a very nice flea market on weekends. No water/sewer at site, but at the exit is one of the nicest dump stations you'll ever see. This is a river island with a causeway built to reach it, so expect lots of bugs. Bring good bug spray. That's really the only negative, though. Nice place and super bargain camping, especially for seniors.
