Most propane grills require around 0.5 pounds of propane per hour. If you plan on cooking on your grill for multiple hours, you will need to bring enough propane to last the entire trip. If you are only using your grill for a quick meal, you might be able to get away with bringing a small canister of propane. However, it is always best to overestimate how much propane you will need, so you don’t run out while cooking dinner. Propane is an important part of any camping trip, so make sure to plan ahead and bring enough fuel for your grill.
