The Intex Excursion Pro kayak has a built-in air pump that can be used to inflate the kayak. To use the air pump, first, open the valve on the side of the kayak. Next, place your foot on the valve and push down until the inflation tube is inflated. Finally, hold onto the inflation tube and pull it towards you until the kayak is inflated. Before getting started, be sure to read and follow the safety instructions before inflating your kayak.
