Named for a small house sitting along the shoreline that captains used to line up with a utility pole to locate the site before mooring balls, Little House on the Prairie is a Swiss cheese paradise full of holes. After spending some time on the open reef to the south, divers pick their way through the interconnected tunnels below the boat like intrepid explorers. Black Bar Soldierfish can be found in little nooks in the reef, often wearing highly fashionable isopod headgear — small crustaceans that live on the fish's head and eat the scraps from their messy meals.

Little House has amazing formations of hard corals right by the boat, including Lobed Star Coral and Mountainous Star Coral, making it one of the go-to sites for coral spawning night dives each fall. Close inspection of these corals reveals the extraordinary reality that tiny individual polyps have built these immense structures over centuries. The combination of daytime tunnel exploration and nighttime spawning spectacle makes Little House one of the most versatile and rewarding sites in the Frank Sound zone.
