On the south bank of the Arkansas River, just below the Interstate 30 bridge, a small rocky outcropping is embedded in the riverbank — this is the actual "little rock" that gave the city its name. French explorers called it La Petite Roche to distinguish it from the larger rock formation on the north bank (La Grande Roche, now in North Little Rock).
It is not a dramatic sight, but it is a genuine piece of the city's origin, and the riverfront walk here is pleasant. A small marker identifies the spot. The Arkansas River Trail passes directly alongside and connects to Riverfront Park.
