We were heading back to our home base and decided to check out this new KOA Holiday and dump our tanks before heading home. The campground (CG) was approximately 10 miles and 20 minutes off I-57 on southern Illinois backcountry roads. Along the way, we encountered a suspiciously low power line that our 13.5'-high rig cleared. Small KOA signs guided us all the way in. We've stayed at many KOAs and particularly enjoyed KOA Holidays for their service and amenities, but this CG was not what we expected. We arrived at a large gravel parking area and found a check-in room at the end of a warehouse, with envelopes on a bulletin board and a phone number to request an escort. Since the RV sites were down a steep hill, we checked our assigned Creek Side site 26 before moving our rig. Sites 23–26 sat in a bowl at the bottom of the CG, with little room to maneuver our 41' fifth wheel and F450. The escort number went to voicemail, but we reached the manager using the CG brochure number. He agreed our rig wouldn't fit and moved us to back-in site 18 on the hill. All RV sites were back-ins. Creek Side sites appeared better suited for smaller RVs, although larger rigs might fit sites 23 and 24. We later discovered the main KOA office near the marina, which handled cabin check-ins, food, and boat rentals. Sites 1–19 were former pull-through motorcoach sites converted to back-ins, with utilities on the opposite side to accommodate other RVs. Our site 18 was exceptionally wide but close to neighboring sites. We positioned our rig toward the right side of the gravel pad (facing the site) to maintain reasonable access to hookups. The electrical pedestal was at the far back, requiring approximately 35' of power cord to accommodate our toy hauler's rear deck. The wide pad provided plenty of parking for a tow vehicle or boat. However, the CG brochure listed a $75 fee for parking boats or trailers at sites, and a marina sign listed a $50 launch fee. We couldn't determine how these fees applied. Water pressure was excellent, so use a regulator. CG Wi-Fi delivered 20.9 Mbps, Verizon had two bars, and T-Mobile had three. Our T-Mobile Home Internet delivered 358 Mbps, allowing us to stream golf and football. With no trees around the RV sites, satellite reception shouldn't be a problem. Some sites had limited lake views, but don't expect panoramic views or direct lake access. The CG had undergone considerable improvements, including attractive cabins, several right on the lake. KOA cabins were mixed with privately owned cabins, while lake access was concentrated near the small marina and swimming area. We expected more direct lake access and walking trails, but neither was available from the RV sites. A standard fenced KOA dog park was available, but longer walks with our pup were limited to a short path around the fishing pond, gravel areas, and CG roads. Considerable work and investment had gone into this CG, but our experience didn't entice us to return.
