Yellow Bay State Park features a concrete boat ramp with deep water access that typically remains ice-free throughout winter, making it reliable for year-round launching. The ramp is steep and well-maintained, accommodating boats even at varying lake levels.

The park offers 5 tent campsites (first-come, first-served), a dock (seasonal, mid-March through November weather permitting), picnic facilities, and vault toilets, with water and flush toilets available mid-May through Labor Day.
