If you are Active, Reserve, Retired military or DoD civilian and are passing through (North) Chicago, this is a great place to spend a night or two. As RV parks go it is pretty basic. 20 back-in concrete pads with electric only. Fire rings at each site. But to be 50 feet from Lake Michigan in a supremely quiet and well-kept park, this is a great bargain. Easy off base access to trains for Chicago for those wanting to see the sights and not fight the traffic. If you don't have a valid DoD sticker for your vehicle you'll have to stop in at the visitor center next to the main gate for a pass. You will be directed to enter through Gate 5, the gate designated for truck traffic at the north end of the base. If you show up after hours, or if Gate 5 is closed, then enter through the main gate. If you have advance reservations, just pull into the RV park and back into your site. Then you can go over to Bldg 13, the Base Marina office, and check in formally. Ditto if you arrive after hours and the Marina is closed (1800 - 6pm). Sewer and fresh water are available at the marina. Since this is a major Navy training base, be ready for lots of marching formations on base, but the RV park is at the bottom of a large bluff, on the lake, and therefore quite removed from other base activities. Sites 1-8 face away from the water; sites 9-20 face and are closest to the water. Since all sites are back-in, it was actually better to be in the sites away from the lake, because then you have a lake view from the back of your rig if that's where the most windows are located. The park is so quiet you can hear a pin drop. Military personnel using it are very courteous and are very non-intrusive. Gas station and mini-mart on base for authorized users; main commissary and exchange are located about 1.5 miles away off base. For $15 and location, location, location, it's great. Or, if you don't want to fight Chicago passing through, it's a great place for a one-night stay. The only reason I rate it a "6" is because it doesn't have all the commercial trappings of other civilian RV parks. But for tranquility and location at a bargain price, this park is hard to beat for authorized users. Definitely big rig friendly, as there were numerous Fifth Wheel and Class A rigs there. We camped here in a Fifth Wheel.
