Cascade State Park system includes Sugar Loaf State Park too. If I am not mistaken a $10 Idaho State Parks Passport will allow you to park in any day-fee area around the lake. I buy it each year with the vehicle registration and put the sticker on my windshield. https://parksandrecreation.idaho.gov/idaho-state-parks-passport-0
I sure does and I always get one just for Cascade and launching at the marina at lucky peak. Saves me a bunch of money.
