Maybe you could try doing what Metroid Zero Mission does and have a texture that fades into a dark color? It looks good because you couldn't really see deep into rock and dirt and such from a character's perspective, so it makes it seem more solid and impassible that way, and the solid color, if picked right, isn't hard to look at for a long time. Repeating patterns could cause eye strain, especially if they're high-contrast.
