East Seelye Bay Campground

First-come, first-served campsites at $16 per night (day-use/swim-beach access fee not specified in sources found).

The swimming beach is an unstaffed USFS day-use area directly beside the boat ramp on an open reservoir lake (Winnibigoshish is Minnesota's 4th-largest lake). No source mentions lifeguards, roped-off swim zones, or water depth/slope at the beach, so caution around boat traffic and unmonitored open water is warranted for young children.

No significant hike is required. The swimming area is close to parking and access.

An on-site parking area serves the campground, boat ramp, and swimming beach. Camping itself is $16/night, first-come first-served, but no separate day-use/swim-beach parking fee is mentioned in any source found.

The campground includes a public boat ramp on Lake Winnibigoshish, and recreation.gov describes fishing, swimming, and boating as available on the lake. No no-wake, electric-only, or carry-in-only restriction specific to this ramp was found in sources checked.

Quiet hours 10pm-6am with generators prohibited during that time; pets must be leashed (6 ft or shorter) but are not allowed in the beach area; campfires must be attended and fully extinguished; fireworks prohibited; only dead/downed wood may be gathered (no chainsaws); OHVs must be trailered to permitted areas.
