It's a very nice campground with lots of trees and the sites are spaced out nicely in the Trillium loop. I've wouldn't pick site 93 however as the pavement is sloped and the whole site is sloped quite steeple. Also, it shares an electrical box with 95 and my camper cord was about 30 ft short.

We stayed here at the end of October. The campground was pretty empty. There are camp sites along Black Lake, which is the 7th largest lake in Michigan. The lake side campsites are very close together but you are right by the water's edge. There is a playground area with swings, sand pit and jungle bars. There is also a boat launch and small beach.

We visited in mid-October. The campground was fairly empty. One complaint we had was that most of the electrical outlets are shared between 2 or 3 sites. The location of the connection point for our site 75 is on the left side of site 77 and our cable could not reach. (See photo). The other issue is that the campground is very close to the main road and you can hear the traffic. Otsego Lake is a pretty big lake and there is a beach area and even a dog beach section. There is a playground area that also has a small baseball field. There are two water fill stations as you enter the park, which is a good idea (also water and two dump stations on the exit side).

We stayed in the Pines campground (not the Modern campground). This has the same entrance as the Modern campground but is a road to the left that follows the river bank. It is rustic campground and no generators are allowed. (You can walk to the Modern campground to use the showers in about 7-10 minutes). The sites are located under tall Pines. The view of the river was beautiful.

The modern campground is a pretty nice campground. There are trees behind which hide the loop behind you. There are a few trees between the camp sites, but these don't offer any privacy. All the sites have electricity in the Modern campground. The campground is about 17 miles from the lower falls.

The drive-in sites are all paved. Some sites are close to the next site but there is a reasonable amount of vegetation between the sites, so they are somewhat secluded. The main restroom has electricity. There is no internet service with Verizon. Occasional texts came through. Unfortunately, you can hear the traffic on US 37. The reservation site shows the camp sites in completely the wrong locations.
