Bring your own food/beverages into the park with a cooler day pass.
Pack a cooler up to 60 qts. with food and drinks from outside the park. This offering is especially helpful, too, if a member of your group has food allergies or restrictions and can only consume certain foods.
Empty water bottles are allowed and can be refilled at no charge at water stations throughout the park. No glass or alcohol is permitted inside your cooler, and your cooler will be subjected to inspection at entry.
No outside food or beverages are allowed into the park without a cooler pass.
