Sugarloaf Public Boat Ramp on Shasta Lake's Upper Sacramento River Arm features 2 launching lanes and becomes the primary access point when lake levels drop below 75 feet (when the Antlers ramp closes).

The ramp is operational down to a 160-foot lake level drawdown and offers day-use access with restrooms available; note that the ramp may close when the parking lot fills or debris creates hazardous launching conditions, particularly in spring months.
