At Elephant Rocks State Park giant boulders of 1.5 billion-year-old granite stand end-to-end like a train of circus elephants. Visitors to Elephant Rocks State Park can easily view the granite boulders from the one-mile paved Braille Trail. Designed especially for people with visual and physical disabilities, the Braille Trail is the first of its kind in Missouri state parks, possibly in the entire state. The path through the site is asphalt and has varying slopes and conditions. In addition, this trail offers interpretive stations with Braille text. Carpet patches followed by a hand-rope mark stations and changes in the pathway. Most of the one-mile long trail is shady and rest areas are provided.

A trail spur brings visitors to a point overlooking an old quarry site. Just outside the park is the oldest recorded commercial granite quarry in the state. This quarry, opened in 1869, furnished facing stone for bridge piers across the Mississippi River, and from 1880 to 1900, millions of paving blocks for the St. Louis levee and downtown streets came from this quarry. Other nearby quarries supplied granite for many major St. Louis buildings.

In addition to the mammoth granite boulders, the trail also passes by an old quarry pond, which now supports a variety of animal life. A short spur off of the trail takes visitors to the top of the granite outcrop, where they can further explore the maze of giant elephant rocks. Thirty picnic sites among the giant red boulders provide ample opportunity for family picnicking and exploration of the elephant rocks. One individual and one group picnic site, located among the trees, have been modified with pavement and extended-end tables.
