Bloomer Group Boat-in Campground is a primitive boat-access-only campsite on Lake Oroville designed for large groups of 9-75 people with up to 25 watercraft, located along the shoreline north of Lime Saddle.

The site features basic amenities including pit toilets, garbage collection, camp tables, and cooking stoves, but no drinking water—campers must bring their own.

Access is by boat from launch ramps at Spillway, Bidwell Canyon, Lake Oroville Marina, or Loafer Creek, and during low water periods, campsites may be a significant distance from the shoreline.
