Ponderosa State Park's boat ramp in the Peninsula Unit is a deep-water ramp with two courtesy docks, suitable for launching power boats and sailboats, with dedicated parking for boat trailers and towing vehicles.

The North Beach Unit also has a small boat ramp better suited for hand-launching non-motorized craft like canoes and kayaks, with a nearby concessionaire offering equipment rentals.

Both ramps provide access to Payette Lake and the Upper Payette River for boating, paddling, and fishing activities.
