The rosy boa's body coloration is pale tan to gray with three deep chocolate brown to reddish brown stripes. It is a small, heavy-bodied snake. Its small head is not distinct from the neck, and it has a blunt tail.

This snake is most active at dusk and at night; in cooler regions it also comes out during the day. The rosy boa will roll itself into a ball with its head in the center to protect itself from predators. It will also release a foul-smelling musk from a gland in its tail.

This species gives live birth to up to 13 young from mid August to early October.
