Everyone has their own mix of essential things to bring. That is a reason to do small trips in the local area to find out what you need. Unlike backpacking through the wilderness, bike touring is usually never far from civilization. You can refill supplies along the way. Places like laundromats, bike shops, restaurants and hot tubs give you an opportunity to refresh yourself and get ready for another day of riding.
Many state parks have programs that encourage bike touring.
Cyclists can often stay in special areas of a state park for reduced rates, even when the regular campground is full. Forest service campgrounds, private resorts and a few motels on stormy nights are good stopping places. Some bike tourists just find hidden places in the woods to camp. Maps and campground guides are easy to find at visitor information booths along the way. Riding carefully and wearing a helmet is an important precaution for any cycling.
