No you don't have to have a reservation you can check availability at the gate as well select dates & pay for your parking permit. I suggest if trying to obtain a RV spot during holiday season reservations our a must.
Don't know 😕
Every time I check at the gate they tell me camping 🏕 at the Yucaipa park is booked until early August. Call Call Call before you drive all the way there and are disappointed.
