The Frio River rises in northeast Real County and flows southeast through Uvalde, Medina, Frio, La Salle, and Live Oak Counties. Totaling in length approximately 250 miles, the Frio is spring-fed in its upper section and flows through picturesque canyons. Garner State Park is located on the banks of this upper section. The waterway is a free-flowing river, since there are no major impoundments or reservoirs located along its entire course.

The banks of the waterway are lined with bald cypress, pecans, and oaks, while cedar and live oak-covered hills rise above the river. Picturesque canyons are formed by limestone outcroppings and bluffs. Few sand or gravel bars are found. Several roads cross the river and provide good access.

While sometimes restricted to private property owners, there are several rope swings along the river route near Ladera Vista. There are also many slow, deeper areas near large boulders, perfect for jumping in.
