Grab lunch, supplies, and water before you set off,  Paia is the last chance to get gas and supplies before you reach Hana. Hana Picnic Co. has all the supplies you will need in one spot, including their famous boxed picnic lunches. The best idea is to  stop along the Road to Hana at one of the many picnic spots and have a picnic with your friends and family, this is the least expensive way to enjoy the trip. They also have great gelato for when you are on the way back.  Make sure to stock up on water too, you’d be surprised how much water is pulled from you in humid climates.
