We strongly recommend river shoes which we have for sale in our store or go to the local discount store, pharmacy, etc. and find a pair - flip flops are not what you need - you need something secure on your foot. If river shoes are not available the next best option is your tennis shoes. You also need sun screen, bug spray, bottled water and snacks. Whatever you bring on the river - you take it out with you. If you wear glasses, we also recommend eye glass holders. If you want to take your cell phone or camera, you will need a dry bag or box. We have these supplies in our store.
