There's no fee to camp on Seboeis public lands and you can stay up to 14 days. That said, because it’s free and extended(14-day) stays are permitted, it can be hard to snag a drive-in, lakefront site. I returned on 3 consecutive weekdays and the only drive-in sites were occupied by the same campers. 

There is some slope to the lakefront sites, but there seemed to be relatively level space to pitch a tent. In addition to a couple of drive-in lakefront sites, there is another one where you park on the road and walk down to, also along the waterfront. 

There are two sites in the‘pit,’ and one of those emptied out the first day I visited, but it wasn’t an appealing area. It is very large and flat, however, so if you have a group or a lot of gear, this may be the best option. If you’re in a tent, be sure to bring a groundcloth to protect the tent, a mattress to cushion your sleep. 

The other sites are accessible by boat with parking available near the boat launch, but there’s not extensive parking here, so plan to arrive early to ensure you get a spot on busy weekends. There’s a boat ramp with a small dock. Latrines provide toilet facilities. Cell phone coverage(Verizon) is spotty once you turn off the main road, but you may be able to find a place to send texts; you can definitely text from the main road and get intermittent data.

Activities include boating (can get choppy when it's windy), fishing, hunting, ATV riding.

The campground is open year round, but you’ll need a snowmobile or skis to get in during the winter. The road starts out paved, then switches into a graded gravel road.
