Extremely large rustic areas available. Right on the river, can leave from there in a bus for a canoe trip that ends right at the campground. Large group sites available in the modern camping area too.
Just to clarify about the Wi-Fi. Yes, there is Wi-Fi near the office and near the house towards the back of the park. I am a seasonal camper there and if you go to the pavilion or the gazebo near the store, you will get Wi-Fi.
