During the First Day Hikes program that began in Massachusetts, participants can go into off-limit areas without guides, and some hikes feature modes other than walking, such as horseback riding and mountain biking.
In some cases, such as at Spring Mountain Ranch State Park in Nevada, guides may take participants into areas of a park normally off-limits to the general public. First Day Hikes is a program of free, guided hikes offered by the fifty state park systems of the United States each year on New Year's Day.
